#69 Shermans you can see running: The Planes of Fame of fame Air Museum

Shermans Tanks In real Life: The Planes of Fame of fame Air Museum

Owning and flying WWII airplanes has been a thing much longer than restoring running tanks, and to this day, WWII aircraft tend to get more attention from Americans than armor or ships. That’s changed a lot over the years, and armor is more popular than ever with collectors, museums and the general public.  There are several Tank museums or businesses around the country with running Shermans. The one we are going to talk about today is the Planes of Fame Air Museum, it is legendary in the Warbird world, because it has so many interesting and rare aircraft. It also has a long, history, and saved some amazing planes along the way, and one tank.

The Planes of Fame air museum has been around so long, it surely had a hand it kicking off the interest in Warbirds that has been popular in the United States since WWII. My Dad, a Baby Boomer, loved warbirds, and his love transferred right over to me, and I ran with it buying more books on airplanes, and tanks than he ever did, and I still have them al.  When I was a kid, we went to the Reno Air Races, and I probably saw Steve Hinton, the President of Planes of Fame flying a racer.  There is something about the roar of a warbird flying by that really gives you a sense of what seeing planes like that filling the sky in the mid-40s must have been like. They have a special sound, and hopefully this is a sound we will hear for decades to come.

Planes of fame got started in the 50s when Ed Maloney started collecting airplanes on a minuscule budget, his museums moved around, but really took root at Chino Airport, where Planes of Fame is to this day. Mr. Maloney had fallen in love with airplanes in high school, and just missed WWII. Shortly after the war he began collecting anything with wings on a shoestring budget for his future airplane museum. He was saddened and disgusted to see the warbirds that helped win WWII unceremoniously melted down for Scrap or for a lucky few to rot away on a remote part of an airport. I know the feeling, it makes me deeply sad to see the piles of P-38s bulldozed off a cliff in the Philippines, because flying them home was a waste of time and money…

By the 60s Ed Maloney had achieved his goal of building a museum and around the same time found a Sherman tank on range on Edwards Air Force base while he was scrounging for B-17 parts. He managed to buy the tank for $1!  That’s not even the best part of the story! The Sherman, a very early production M4A1 75 tank, still ran! It had been sitting on Edwards for at least a decade untouched, and they got it running. The tanks interior was not gutted, though some things like the hull ammo boxes had been removed a lot of the important parts were still there. They collected more parts over the years, and serious restoration started in the 80s and continues even now.

Ed died in 2016, and it was a huge loss for the aviation community. Sometimes, when a man with a love for, and a collection of things like airplanes or tanks, when the man passes on, his labor of love dies with him, I know of a least two cases.  The Littlefield collection only lasted a few years before his widow grew tired of it and donated it to a great museum on the east coast, but to build a place to keep it they sold most of it off, and now can’t build the new facility because of zoning problems.  That wasn’t a worry of Ed Maloney, because PoF is a family affair. Steve Hinton, who took thinks over when Ed passed, has been around the place since he was a kid, and his best friend was Ed’s son. I’m also pretty sure Steve married Ed’s daughter! Planes of Fame lives on, stronger than ever, and with another generation working and flying the planes, I think they have a bright future.

This image is from Warbird Depot, a great site for the airplane lover! This is the Planes of fame F4U-1 Corsair, one of the earliest flying Corsairs!

Now you might be wondering how a bunch  of airplane people can keep a tank working, but trust me, they have guys there who can keep an F4U-1 Corsair, with a magnificent Pratt and Whitney R-2800 running, they can figure out a simple Sherman. The nice thing about a Tank is it handles the weather a lot better than an Airplane, though being stored outside unprotected still isn’t good for them. The Sherman in particular has some very sturdy components, and more often than not, if the powertrain remained sealed up, even after decades on the firing range, if it didn’t get penetrated, they rarely needed much work to be operational again. The engines are a bit less robust, but in a nice warm dry environment, they could last a surprising amount of time as well.

Currently the Planes of Fame M4A1 is about 50% complete, and they restore a little more every year, as money and parts allow. I’m sure in some cases things have to be fabricated. It has a little Joe back auxiliary generator inside, has a working stock electric traverse system, but the stabilizer needs a little more work. The electric firing system works, and though the main gun is de-milled, it can still fire 75mm blanks. A blank firing co-ax M1919 machine gun can be fired with the foot switch, just like the main gun. The intercom is complete and works at all stations, as does all the interior lighting. A place like PoF probably has little trouble keeping the R-975 radial running either.

This summer the turret comes off, new ammo boxes go in and they will complete the interiors restoration. The M4A1 is already a part of their shows, but it is also available to rent, TV, Movies, Weddings, you name it, I could see an M4A1 being a cool addition!  I hope to get down there sometimes in the next year or two and check the place out.

The real Zero planes of fame has, with the real motor that belongs in it, and it was used in the movie Pearl Harbor, making a not so great movie a must see. Image from the wonderful www.Warbirddepot.com

If you are in the area and have even the smallest interest in aviation, you owe yourself a trip to Planes of Fame Air Museum in Chino California. The Sherman tank is of course going to see all on its own, but they also have a real Japanese Zero, with its correct engine and it flies! Even crazier? It was used in the Ben Aflack movie Pearl Harbor! Steve did all the flying, but they wouldn’t let him shoot Ben down for real!

Sherman Tank Site, News Post 9: DATA, DATA everywhere!

News Post 9: New Years News

I decided I needed more hard numbers, the kind of data that makes non tank nerds eyes roll up in their heads, stuff like how many spare periscopes were issued with an early war M4A1! One of the best way to do this is through tank Data sheets, as found in the back of many books on tanks. I used Hunnicutt’s Sherman book for some, but others I’ve made using the Hunnicutt ones as a template and then using data from the Technical Manual for the tank.

We had four, now have spec sheets for 15 different models of Sherman, and 3 Lees! You can find them all on this page. Shermom Model specification sheets. 

90mm GMC M36B1 Spec Sheet PDF

That’s not all though, I decided the gun Data sheets in Hunnicut were really interesting, so I started replicating those, but with an improved format, and slightly more data.  These gun Data Sheets can be found here, Main Guns: THings that go  BOOM!  All the guns the Sherman tank used are covered, and more are coming.

m1-M1A1-M1A2 guns 76.2 Sherman tanks

In the works are Data Sheets for each Sherman tank motor, and several experimental models. These Data sheets will have much more detailed info on the motor, and will include interesting images from the manuals for the motors.

Also in the works as dedicated pages for these data sheets, the beta test of the gun version is up and can be found here.  Next up will be ones for each tank model and then motor.

Also note the latest post on the Ram tank, The Ram: The Shermans awkward Canadian Cousin. This post covers the Canadian and British attempt to come up with a better Sherman before the Sherman design and prototype was done. I’ve been sent some very interesting documents, some are included in the post.

Thanks for reading and stay tuned for more Sherman information!

 

#64 Sherman Fire Control: How the Gun Was Aimed, not Putting Out Fires!

m4a1-haa27

Sherman Fire Control: How the Sherman aimed its Main Gun.

The Sherman tank went through a series of fire control changes each an improvement over the last.  The first tanks lacked telescopic sight mounted on the gun mount. The only site was incorporated into the gunner’s periscope, and it wasn’t magnified. Since the periscopes were all interchangeable, updating the older tanks was easy at least were the periscope was concerned.

The final fire control setup the Sherman gunner had at his disposal was pretty impressive by the standards of the time. He was in a hydroelectrically driven turret that rotated fast; he had very nice periscope setup with 1x and 6x scopes hooked into the gun with strong linkage.  He also had a telescopic sight to work with and the gun was stabilized.  This was a vast improvement over the unmagnified reticle on the first production models.

The Lee used a unique setup; the 75mm gun was aimed with an M1 periscope, with an M21A1 periscope built into it. The 37mm was aimed with an M2 periscope with an M19A1 periscope built in. Both the 37 and 75 mounts were stabilized. The prototype M6 Sherman used its own unique sight built into the sight rotor on the top of the turret, this was only used on a small number of production Shermans tanks.

Let’s look at the various periscopes and telescopes the Sherman used through its long life.  Let’s start with a look at the various versions of the periscope sights the production Sherman and the TDs based on the chassis below.

 

The M3 Periscope Sight

Since I just have a little info on this from TM 9-731B on the early M4A2, don’t have much to put here. Maybe this periscope is the one I’ve read about getting foggy on the inside in cold or humid locales. It was quickly replaced with the M4 detailed below.  This was one of the non-magnified periscopes.

m3-periscope-sight-for-use-on-early-shermans

The M4 Periscope sight

The Periscope M4; it had an M38 telescope with ballistic reticle inside, but no magnification. The M4 was not well liked, and the mount it fit in, was made from sheet metal and was a little flimsy.  The linkage that attacked it to the gun wasn’t very robust, and could be knocked out of alignment annoyingly easily.  On early Shermans this was a big complaint, since they did not have a direct telescope yet. You couldn’t really take advantage of the M3 75mm guns range with this sight setup either since it had no magnification. The later better periscopes like the M4, M4A1 and M8 series would all fit in the old mount though.

 659_003

The M4A1 Periscope Sight

Next came an improved version of the M4, the M4A1, and they came with an M38A2 telescope, this one was magnified, but not much at 1.44x, and a 9 degree field of view. Later versions of this periscope had illuminated reticles. The mount was not improved though nor was the linkage.  The M4A1 periscope was changed when the 105mm and 76mm armed Shermans came online, when used with these guns, they had the M47A2 for the 76 tanks, and M77C for the 105 tanks. Hunnicutt doesn’t specify if these were also 1.44X. This periscope was found on M4A1, A2, and A3 76 tanks during WWII.

 m4a1-peridcope-76mm-guns

The M8/M8A1 Periscope Sight

The M4A1 periscopes were replaced by the M8 and M8A1 periscopes. They were a lager tougher improvement on the M4 series, and had the M39A2 telescopic reticle for use with the 76mm gun, since it had the same reticle as the M47A2 used in the M4A1 periscope.  The M39A2 had 1.8x magnification, and a 6 degree FOV.  Even though at this point this was no longer the primary sight, the Army kept improving it. But the mount and linkage still remained an issue.

 s-l225

The M10 Periscope Sight

The Army came up with another new periscope sight system called the M10. They started issuing it late in the war around the same time wet tanks start appearing. This was a much improved periscope; it incorporated two telescopes with reticles, one 1.x, with a field of view of 42 degrees, ten minutes for engaging close targets. The second periscope had a 6x telescope with an 11 degree 20 minute field of view. This periscope could be used with the 76, 75, and 105mm guns when the right reticle was fitted. There was also an M16 periscope, pretty much the same as the m10, but with a reticle adjusting system.

M10C was specific to 75mm Shermans.

M10D was used on 76mm tanks, and 105 tanks.
m10f-periscope-for90mm-apps m10f-periscope-for90mm-appsback 

recticles-for-m10f-periscopes

The Periscope mount

for these periscopes were improved greatly when the 76mm gun and 105 tanks arrived, and the mount was made from a beefy casting, and all the linkage was made much stronger will ball bearing in all the pivot points. These would have shown up on M4A1 75w, M4A3 75w, M4A3 105, M4 105, and M4A3 76w, M4A2 76w and M4A1 76w tanks.

You can see the old style periscope mount in this shot.

This improved mount was also incorporated into most of the post war rebuild and overhauls. It is very easy to spot, by the heavy cast iron hood over the periscope hole.

In this shot you can see the improved heavy duty gunners periscope mount, spikes optional.

The Telescopic sights.

The Shermans fire control system was improved further by the incorporation of a direct telescope mount to the M38A1 gun mount. This prompted the creation of the full length gun mantlet to protect the scope. When these were retrofitted into older tanks, sometimes they would weld on armor over the scope, leaving a half armored mantlet.

The later 76mm armed tanks had the M62 mount, and it had a telescopic sight mount from the start.

The direct scopes went through their own evolution, and this information is put together from the various TMs on the tanks and Hunnicutt’s Sherman, and is not complete. I will update this section as I get more info on the topic.

The M55 Telescope: The first! For the 75mm and 105

This telescope had 3x magnifications with 12 degree 19 minute FOV. This sight was also used on the early production 105 tanks and most 75mm Shermans.

m55

The M51: Also the First, but for the 76 M1A1

The same scope as above, with the same specs, but with the reticle for the 76mm guns, and that’s all. There were complaints about the optical quality on these scopes, since the clarity wasn’t optimal.

M70 Telescopic Sight

The M50 sights were replaced with the M70 Series sights, the same size and magnification. What set them apart was there superior optical quality. The Army went on to develop many different versions of this sight. It was a 3X scope with a 12 degree 19 minute FOV.

M70F Telescopic Sight

This was version used on M4A3 75W Shermans.

m70fusedon75mmmtanks m70frecticle75mmsherman

M70G Telescopic Sight

This sight was used on M10 GMC tank destroyers.

M70P Telescopic Sight

This sight was used on some M36 CMCs tank destroyers.

M71D Telescopic Sight

This was a 5x with a 13 degree FOV version of the scope. It had the reticle for the 76mm guns and was used on those tanks. This was the sight commonly found on M4A1 and M4A2 76 tanks.

M71G Telescopic Sight

This version of the M71 was issued with the Jumbo tanks.

M72D Telescopic Sight

This was used on the 105mm armed Shermans.

M76F/D Telescopic Sight

These telescopes were used on the M36 GMC tank destroyers.

m76f-90mm-sight m76f-90mm-sight-2

M76G Telescopic Sight

This scope only had a 3x magnification, with a 21 degree, 30 minutes FOV, and was used in 105 tank applications later in the war.

M83 Veritable Power Telescopic Sight.

This scope had two settings, 4x 7 degrees, 40 minutes and 8x 4 degrees, 15 minutes, and M83D version of this sight worked with the 76mm guns when in an M62 mount. I have not seen this one mentioned anywhere but Hunnicutt’s Sherman book. That doesn’t mean it didn’t get issued as a replacent later in the war, since I’m going off TM’s and spec sheets and those are a small snapshot into a tanks actual combat gear.

. . .

 

Indirect Fire Control Gear

You would think that would be it for fire control equipment, but it’s not, because all Shermans came equipped with the equipment for their tanks to work as impromptu artillery batteries all Sherman based TDs had this gear as well. The US Army had this extra gear installed all the way up to the M60 tanks. During the war, some tank and TD battalions were very good at being artillery; other units didn’t train for it, and were not good.  This was a good way of keeping tanks useful in Italy, and they filled this role a lot there. I do not think this was something many other nations did with their tanks.

Azimuth Indicator M19

The Azimuth Indicator was mounted near the gunner, right behind the traverse control. This device was used to dial in what direction the gun needed to be pointed in to carry out the fire mission.

azimuth-indicator

Gunners Quadrant M1

The Gunners quadrant is a portable precision instrument used for measuring the elevation or depression angles of guns and howitzers. It can also be used for checking the adjusting of elevation devices on sighting equipment furnished with a gun or howitzer. This was taken right from the Characteristics in tech manual 9-1527.

Elevation Quadrant M9

The Elevation Quadrant M9 was used to lay the tanks main gun in elevation for indirect fire. There are detailed instructions for setting it up in TM 9-748.

m9-elevation-quad

A Sherman unit trained in how to act as an artillery battery would probably be told they were on call when not in direct combat but close enough for the 75s to reach. They would have men manning radios in the tanks while other tasks were being done, like maintenance, personal things and eating. When they got the call, the designated battery commander for each platoon would listen to the directions on the arty net or get in direct contact with the spotter. In many cases they would wired into the directly, so they wouldn’t need to worry about radio reception. They would relay the aiming information out the tanks on the radio or phone net and then they would start firing.

755tb_italy_44
M4 being used as artillery

Once they started firing the hole crew would help feed the gun, and if they were doing it as a common thing they might even have large amounts of ammo unboxed outside the tank, where the driver and co-driver could feed them to the commander who then fed  them to the loader.  The M3 75mm gun worked well in this role, since the barrel had a life in excess of 4000 rounds.

#63 Security On the March: How a WWII Sherman Tank unit prepared for an attack on march.

Security on the March:  With the Sherman Tank

seconmarch

Tank and AFV News posted a link to a fascinating YouTube video covering march security of mechanized units, the film is from early 43. This Army training film is almost a half an hour long, and it’s really interesting, and has some rare shots of men working inside a Sherman.  The film takes place somewhere in the US, probably on a Hollywood backlot, the Desert Training Center was pretty close so getting the tanks to Hollywood wouldn’t be hard. At times the film is clearly using special effects, and that lends more credence to it being done in Hollywood. The film covers security on the march, and does it by covering a tank platoon, and what it should be doing. It covers night movement, camouflage when stopped and gives tips on being stealthier in your tank; it also covers how to use the columns firepower if attacked from the air.

m4a1-haulingrear-from-army-training-filmm4a1-haulingrear-from-army-training-film4

The tanks used were all early M4A1s, but not super early since they are not DV tanks, but still have shorty gun mantlet and no telescopic sites, they do have heavy duty suspension as well. The tanks also have full turret baskets, with the 12 unprotected ready rounds, and no armor over the sponson ammo racks or the turret cheek add-on armor. Its possible training tanks did not have these features removed like tanks slated to see combat, or the film was made very early in the war.

m4a1-haulingrear-from-army-training-film12
This image shows the big picture of a moving column a troops. This film only covered the role of the main body.

It is an Official War Department Training film, number T.F. 21 2035, and I want to make sure and thank Jeff Quitney for putting it up on YouTube! I had never seen it before so it was a real treat.  He has a lot of other good content up on YouTube as well so check it out.

m4a1-haulingrear-from-army-training-filmm4a1-haulingrear-from-army-training-film6

Now let’s talk about the contents of the Training Film.

Right off the video starts off with a M4A1 driving by on a dirt road, it’s going at a good clip, and you can just make out another M4A1 trailing behind it at a few angles. The next shot shows a tank crew in front of their M4A1 going over a map with commander, and it just keeps getting better. I took well over 100 screen caps watching this film.

m4a1-haulingrear-from-army-training-film8m4a1-haulingrear-from-army-training-film7

The training film makes it clear there are the five things that need to be kept in mind at all times to make a road march safe.

  1. Advanced prep
  2. Alertness
  3. Concealment
  4. Dispersion
  5. Firepower

 

The enemy’s goal in an ambush would be to get to the main body of the column, and the film talks about how they should move, and covers things down to where each vehicle is to point its gun, to be prepared for an attack that might come either from the air, or ground. The film focuses on the actions of a single, five tank, platoon in the main body of the column, and then covers each of the five steps previously mentioned, and how that platoon would do them.

 

  1. Advanced Preparation: Because good prep makes for smooth operations.

  • Be ready for gas, liquid vesicant detector paint, this pain, turns green to red when vesicant gas droplets touch it. A large square of this stuff was painted on the front of the tank. Then the decontaminator stored in the tank could be used to spray down the tank. The crew was also issued gas masks, and this was the time to make sure they were in working order.

m4a1-haulingrear-from-army-training-film13 m4a1-haulingrear-from-army-training-film14 m4a1-haulingrear-from-army-training-film16 m4a1-haulingrear-from-army-training-film15

  • Check the tanks readiness out. The Commander needs to check the tanks fuel level personally. The Crew, checks the engine out, checks the tracks, and checks out the ammo load. Do not leave with an empty ammo rack if ammo is available. Main gun rounds should be clean and undented.

m4a1-haulingrear-from-army-training-film17 m4a1-haulingrear-from-army-training-film18 m4a1-haa5png m4a1-haa3png m4a1-haa1 m4a1-haa2

  • Platoon leader review whole route on the map with all tank commanders. Cover all points of interest along the route, likely ambush spots, landmarks, areas of good cover for rest points etc. Each tank commander will then pass all this info along to all his crew members, ensuring they can all fill in for each other. If one tank has to fall out for any reason, its crew knows the whole route and plan.

m4a1-haa10 m4a1-haa11 m4a1-haa12 m4a1-haa13 

 

  1. Alertness: Because surprise is the enemy’s best weapon, always be on guard for attack, air or ground.

  • Every man in each tank turret is an air observer, the Tank Commander should always be looking around the tank, scanning the ground and air, and looking back. The Co-Driver should be watching the flanks, because the Driver is watching the road. The gunner and loader should be using their periscopes, all scanning for an attack.

m4a1-haa18 m4a1-haa19 m4a1-haa20 m4a1-haa21

  • The crewmember in the turret hatch needs to be alert, so when the commander is tired and needs to take a break, the gunner or loader will swap places with him. The Commanders position, no matter who is manning it has to be ready to receive signals from the platoon or company commander and pass them on, be they flag, or hand or radio. He also has to be able to see a messenger that needs his attention. The Loader should help the commander tend the radio, and the crew should listen to the radio to keep informed.

 

m4a1-haa31 m4a1-haa32 m4a1-haa33 m4a1-haa35

  1. Concealment: Keeping a 32 ton tank as hidden as possible!

  • Dust is bad. You can’t hide tanks in a dust cloud, so don’t drive on soft dusty shoulders if you’re on a road. Even if that shoulder is shady, and will make the tank more pleasant inside, the dust can be seen for miles. Sometimes it can’t be avoided, but try to do so as much as possible. Line formation is best for use in places dust cannot be avoided. Driving at a slower speed can help minimize dust as well.
  • Shielding Terrain is to be taken advantage of anytime it won’t produce large amounts of dust.
  • Shade is ok is it does not make extra dust, and can help hide you from air observation.
  • Your goggles can reflect light for miles; if you’re not wearing your goggles store them in the tank. If they are needed to protect your eyes, they should be covering them. This applies to any shiny object.
  • Do no silhouette your tank on a hill or high ground. Drive around the base of the hill. If you have to drive on a hill stay below the crest.

m4a1-haa63 m4a1-haa61 m4a1-haa50 m4a1-haa62 m4a1-haa45 m4a1-haa44

 

  1. Dispersion: Bunching up is bad, if you are to close one artillery round, or bomb can damage multiple vehicles.

  • Bunching up like a bunch of cows with their tails in the breeze is bad. This makes you a big target.

m4a1-haa65

  • Proper daylight spacing is at least 75 yards between tanks. If visibility and terrain allow, you can have more than 75 yards, but never less.  In hilly terrain it is easy to bunch up, keep your eyes on the tank in front of you if it starts slowing down; you will have to as well.

m4a1-haa66 m4a1-haa54

  • Falling Out. If your vehicle has to fall out for some reason, engine troubles, or some other issue, make sure you pull far enough off the path to not cause a bottleneck on the path, and slow the rest of the column. Make sure and signal the column and platoon so they know what is going on. Don’t try and catch up, wait for a halt, then retake your position. Fall in with the rear guard until the halt.

m4a1-haa70 m4a1-haa71

 

  1. Firepower: A Sherman tank packs a lot of punch, keep it ready, it’s your ace in the hole

  • The main gun should be trained out and ready, but not loaded. The lead tank and the next in line keep their main guns aimed straight ahead. The third tank in line keeps its gun trained out to the right. The fourth tank keeps its gun trained out to the left. The fifth tank will have its main gun traversed to the rear.

m4a1-haa74

  • M2 .50 anti-aircraft guns should be kept half loaded, so they can be quickly brought to bear on any attacking aircraft. To keep the column covered, alternating tank commanders look forward and to the rear during air attack.

m4a1-haa75 m4a1-haa76 m4a1-haa77 m4a1-haa78

  • Do not halt, during an air attack. Your tank is much harder to hit when moving. Even if you have good concealment, do not stop. When a plane is sighted signal the rest of the column, close all hatches but the commanders, alternate the .50 AA guns and engage the aircraft.

m4a1-haa88 m4a1-haa89 m4a1-haa90

  • Report the results of any air attack up the chain of command. TCs report to Platoon Leaders, Platoon Leaders to Company Commanders, etc.

m4a1-haa91

 

Halt security: Units on the move have to stop, for human reasons or mechanical ones, and you can’t just do it willy-nilly, there’s a plan for that too.

There are two kinds of stops a unit on the march will make. The short ten minute halt, to check the tanks out, for the crews to stretch their legs, no major maintenance will be taken on these short halts. The second kind is the Long halt. On the long halt, the tanks can be repaired if anything major popped up and refueled, and the crews could get some chow.

Security rules and things to note on the short halt:

  • Check the ground where the tank will be parked, make sure the tank won’t get stuck, or sink in. Back into the spot so you will not have to back out if the tank needs to move out in a hurry.

m4a1-haa94 m4a1-haa95 m4a1-haa96 m4a1-haa97

  • First Echelon Tank Maintenance should be done on the short halt, check the tracks, tighten the end connectors, check the motor out, lube as needed.

m4a1-haa113 m4a1-haa114

  • Review the course, check out the route the column is taking on the map, and review it with your crew and the rest of the platoon.

m4a1-haa99

  • Be Alert, post guards, at least two from each crew. One man must always be on the platoon leader’s radio. Do not let the enemy sneak up on your position.

m4a1-haa100 m4a1-haa101

  • Disperse on the halt, in the same pattern as on the move; each tank is still responsible for covering the area they were covering with their main gun. Use any cover available on the halt to conceal the tanks as best possible from air or ground observation. Spacing cannot be less than 75 yards.
  • Each tank will have the commanders .50 manned.

  • When pulling out, each tank will keeps its spacing, and will not stop on the road to form up. 

m4a1-haa108 m4a1-haa109

Security Rules and things to note on the long halt:

  • All the rules for a short halt apply
  • You can pull further from the road on a longer halt. A guard has to be posted near the road to receive any signals though.
  • Dig Prone Shelters, you might not be able to get back into the tank in a surprise air raid or artillery attack.

m4a1-haa112

  • Eat while you work, you never know how long the halt will be.
  • Take more time to conceal the tanks, cut or break off tree branches and use them to break up the tanks lines. Rake the tanks tracks leaving the road away.

m4a1-haa119 m4a1-haa115 m4a1-haa116 m4a1-haa117 m4a1-haa123 m4a1-haa124

  • Use shade and any local cover to hide the tank, move the tank as the shadows used to hide them move with the sun.

m4a1-haa120 m4a1-haa121

  • If no cover can be found, use the camo net.

m4a1-haa122

  • Some camo is better than nothing.

Special Rules for night marches:

  • If under air attack, Stop, for both concealment, and to prevent bunching up.
  • If under air Attack, Do not fire, unless you are sure you are spotted.
  • If under air Attack, Turn off your marker lights, the video doesn’t say this, and they used models in the film, but I think it’s a safe assumption.
  • No light, not even a smoke, and smoking is bad anyway, mmmkay.

 m4a1-haa125

 

Now for some thoughts on the film, it is really very interesting for several reasons, and the quality is very good. The main reason it’s interesting is the look at prewar combat, or pre air superiority march doctrine. The attention paid to defense from air attack would not be pushed nearly as much even by the Italian campaign and would be almost an afterthought by Normandy. Later films probably pushed very carefully searching for well concealed AT guns and infantry that the lead and flank scouts may have missed.

It is also interesting how gas attacks and preparation for them is first thing they cover. I’m sure shortly after most unit got in combat they ended up losing or discarding most gas related gear, and I can’t ever recall seeing a man carrying a gas mask case or a square of the gas detecting paint on any vehicles in combat photos.

The night shot of tanks moving is clearly done with models. The machine guns used during the mock air raid also appear to be prop guns. If you watch carefully, most of the film, the .50 M2s have the normal short cooling sleeve with round holes, during the shooting scene, these have slotted sleeves, and the barrels do not seem to recoil at all.  The explosions look like typical Hollywood fare as well. It should come as no surprise Hollywood was willing to help the war effort; this is just one example of many. All the big studies did propaganda movies and even Bugs bunny and Disney got into the act.

I have been looking the tanks over, they are all M4A1 75 tanks, they are all small hatch hulls, but none are DV, they all have heavy duty suspension bogies. Two have three piece cast differential housings, the rest have the first version of the cast one piece diff housing. The turrets all look the same for the most part, with the short mantlet, so M34 gun mounts with no telescopic sights. Some of the gun mounts have slanted lift rings, others don’t seem too. At least one turret has the port for the spotlight on the roof. One tank has the siren mounted in the front plate with the odd single brush guard, the rest seem to have them mounted on the fenders.  Two or three of the tanks appear to have T54 steel chevron tracks, while two or three seem to have T47 steel bar cleat tracks. I’m bad at spotting the little clues that give away who made what, but I think two of the tanks were made at PCF in Washington; I think the two tanks with three piece diffs are from PSC in Illinois.

#52 Soviet Shermans: The Soviet Union Used and Liked the Sherman

71IIXN+-6bL._SX355_

Soviet Shermans: The USSR Was a Big Sherman User, and They Liked it

soviet-sherman

The Soviet Union received three American Medium tank types in large numbers. They received the Lee, and M4A2 75 and 76 tanks. Only the UK would use more M4A2 tanks, though they received only five armed with the 76mm gun, they got far more of the 75mm armed M4A2s.  The Soviets also received a pair of M4A4 tanks for evaluation, but rejected them because of the motor.  My impression from the things I’ve read says, they liked the all of them, well not the A4, but liked the Shermans more than the Lee.

Now let’s cover each tank model.

M3 Lee: The Basic Lee

Podbitie_Sovet-tanki-M3-General-Lee_1942
Knocked out Soviet M3 Lee tanks

The Lee was not considered a very good design by the Soviet Union, you can read their evaluation here, on Archive Awareness, but it was not all negative. They liked the transmission, differential and final drives, and in particular the steering and brake mechanism.  They felt the R975 air cooled motor was not a great fit for tanks, for all the reasons they are not fit for tanks, mainly the size limitations they put on the tank, and as gasoline AC engines, they don’t have good low end torque, make driving harder.  They disliked the 75mm guns position, and lack of sites on the machine guns.

Soviet M3 Lee, If you look closely you can see grousers installed on the tracks

One thing I found very interesting, is in the summer, they could pack up to 10 SMG infantry into the Lee, along with the regular 7 man crew, making it into a makeshift APC. The thing would be packed full of people though.  The report says all weapons could be fired on the tank while those 10 men were stuffed in, so I guess the US Army or Brits didn’t try this because they liked comfort or something.

The Lee did not fare well against the upgraded Panzer IV with long 75, and they lost a lot of them, but they never stopped using them, they just did what the British did and sent them off to secondary theaters, were tanks were useful, and no enemy tanks were around.  Against poorly equipped, in AT weapon, Infantry, the M3 Lee was a monster of a tank. The 75mm had a great HE round, it was packed with machine guns, and had a 37mm that could sling canister.  The Soviets received 1386 M3 Lee tanks.

M4A2 75 dry: Early Small Hatch 75mm Shermans with Drivers Hoods

PGJKg7U

The Soviets received 1990 M3 75mm gun armed M4A2 Shermans. I don’t have a list of who made the early M4A2 tanks they got. They were competing with the Marine Corps and the French and Brits on priority for these tanks, and most went to the Brits.  I’ve looked through a lot of pictures of Soviet M4 tanks, or “Emcha” as they seemed to call them, the small hatch 75 tanks seem rarer than the large hatch 75 and 76 tanks.

This Post on Archive Awareness indicates, they received several hundred very early M4A2 tanks. One of the big indicators of this is the section where they talk about the suspension having the Lee style top mounted return roller, which could be jammed with mud, but then they received later models, where this return roller was moved to bracket mounted to the side of the suspension unit.

Another interesting part of that document is the problems they had with injectors, and lubrication problems with the pistons.  The Army reported similar problems with early model M4A2s, with the Air cleaners, cooling system and clutches, but nothing about the injectors.  This post on AA also indicates injector issues, but was overall positive on the M4A2.  Maybe the Soviets used low quality diesel and the injectors didn’t like it. At any rate, these issues would have been worked out by the time they started getting improved models.

M4A2 large hatch Dry: Late Model 75mm, 47 degree Large Hatch Hulls, but with Dry Ammo Racks

soviet-Shermans
M4A2 75 dry large hatch tanks in action

By late 1943 a new version of the M4A2 was going into production, and it had the improved 47 degree, single piece front armor plate, with large driver and co drivers hatches. These would be the first tanks to get this improvement.  By the time this model went into production, priority for diesel powered Shermans was going to the Soviets, since that was the only model they wanted, and the Brits would take the M4A4.

An final production M4A2 75 dry tank

These improved large hatch hulls still used the dry ammunition rack setup of the early small hatch hulls, but they had the applique armor applied at the factory, and the 75mm turrets had an improved casting thickening the area that had required welded on additional armor on the older turrets. The Turrets had a oval loaders hatch and a pistol port as well, though the commander still got the older split hatch cupola with the 50 caliber mount built into it.

These tanks seemed to have been photographed much more than the small hatch 75 tanks, but I do not have a lot of photos of either. By the time these tanks were being produced, all the major reliability issues would have been worked out.

M4A2 76W: The Soviets were the Second Biggest User of 76mm Shermans

Production of the 75mm armed Sherman was reduced, as Sherman production was streamlined down from the 10 factories that were producing it, to the three that would  finish it off, Fisher, Chrysler, and Pressed Steel Car.  The Soviet Union received 2073 M4A2 tanks with the 76mm M1A1 gun.  This was just about Fishers whole production run on the 76mm armed M4A2.

These tanks would have started out with wet racks, all around vision cupolas, a split loaders hatch and an M1A1 76mm gun without a barrel threaded for a muzzle brake.  A few may have even had T23 turrets without the ventilator on the rear. These would quickly be replaced with M1A1C guns with threaded barrels with a protective cap over the threads, and the split loaders hatch would be replaced with the smaller oval hatch.  These tanks would eventually be produced in the “Ultimate” configuration, with the M1A2 gun, and HVSS suspension.

These thanks saw extensive combat use with the Soviet Union, use with Guards units. My understanding is the Russians liked the M4A2 76w tanks just fine, and used them in elite units, but this has no reflection on their feelings about the tank compared to their own T-34-85 tanks.  T-34s were used in Guards units as well, and some units had both, as we can see from this AA post.  By that point in the war the Sherman and T-34 were pretty close in abilities.

M4A4: They Received Two, and that was Enough to Convince them, They Wanted No More

m4a4side

The Soviets sent a group of officials and engineers to check out the Chrysler Defense Arsenal,  to review the world famous tank factories abilities, and the tank they were currently making, the M4A4. This visit took place between December of 42 to February of 43, for more details, see this post on AA.

After being given a chance to drive the M4A4 on the proving grounds and being given lectures and demonstrations of its A57 gas motor, the Soviets decided that the M4A4 was better than the M3 Lee, but inferior to the M4A2 with GM Diesel they were already receiving through lend lease. They decided the factory was impressive, but really not producing a very good tank.

Even though the Soviets showed little interest in the M4A4 tanks, two were sent to them for evaluation anyway. You can read their impressions here, but as before when they tested it in the US, they felt the motor was to complicated to be reliable.

. . .

Here are some quotes from the ‘I remember’ interview of Dmitriy Loza, Hero of the Soviet Union, pertaining to the Emchas.

 

Dmitriy Fedorovich, on which American tanks did you fight?

On Shermans. We called them “Emchas”, from M4 [in Russian, em chetyrye]. Initially they had the short main gun, and later they began to arrive with the long gun and muzzle brake. On the front slope armor there was a travel lock for securing the barrel during road marches. The main gun was quite long. Overall, this was a good vehicle but, as with any tank, it had its pluses and minuses. When someone says to me that this was a bad tank, I respond, “Excuse me!” One cannot say that this was a bad tank. Bad as compared to what?

 

Dmitriy Fedorovich, did you have just American tanks in your unit?

Our 6th Guards Tank Army (yes, we had six of them) fought in Ukraine, Romania, Hungary, Czechoslovakia, and Austria. We ended the war for us in Czechoslovakia. Then they rushed us to the Far East and we fought against Japan. I briefly remind you that the army consisted of two corps: 5th Guards Tank Stalingrad Corps on our own T-34s and 5th Mechanized Corps, in which I fought. For the first time this corps had British Matildas, Valentines, and Churchills.

 

They delivered the Churchill later.

Yes, a bit later. After 1943 we largely declined British tanks because they had significant deficiencies. In particular, they had 12-14 h.p. per ton of weight at a time when good tanks had 18-20 h.p. per ton. Of these three British tanks, the best was the Valentine produced in Canada. Its armor was streamlined but more importantly, it featured a long-barreled 57mm main gun. My unit switched over to American Shermans at the end of 1943. After the Kishinev Operation our corps became the 9th Guards Mechanized Corps. I missed to tell you that every corps consisted of four brigades. Our mechanized corps had three mechanized brigades and one tank brigade, in which I fought. A tank corps had three tank brigades and one mechanized brigade. Yes, we had Shermans in our brigade at the end of 1943.

 

But the British tanks were not withdrawn from service, so they fought until they were gone. Wasn’t there a period when your corps had a mixture of tanks, both American and British? Were there any problems associated with the presence of such a broad variety of vehicles from different countries? For example, with supply and maintenance?

Well, there were always problems. In general, the Matilda was an unbelievably worthless tank! I will tell you about one of the Matilda’s deficiencies that caused us a great deal of trouble. Some fool in the General Staff planned an operation and sent our corps to the area of Yelnya, Smolensk, and Roslavl. The terrain there was forested swamp. The Matilda had skirts along the sides. The tank was developed primarily for operations in the desert. These skirts worked well in the desert-the sand passed through the rectangular slots in them. But in the forested swamps of Russia the mud packed into the space between the tracks and these side skirts. The Matilda transmission had a servomechanism for ease of shifting. In our conditions this component was weak, constantly overheated, and then failed. This was fine for the British. By 1943 they had developed a replacement unit that could be installed simply by unscrewing four mounting bolts, pulling out the old unit, and installing the new unit. It did not always work this way for us. In my battalion we had Senior Sergeant (Starshina) Nesterov, a former kolkhoz tractor driver (Kolkhoz is sort of farm – Valeri), in the position of battalion mechanic. In general each of our tank companies had a mechanic and Nesterov was it for the battalion. At our corps level we had a representative (whose name I have forgotten) of the British firm that produced these tanks. At one time I had it written down, but when my tank was hit everything I had in it burned up -photographs, documents, and notebook. We were forbidden to keep notes at the front, but I did it on the sly. Anyway, this British representative constantly interfered with our efforts to repair separate components of the tank. He said, “This has a factory seal. You should not tinker with it!” We were supposed to take out a component and install a new one. Nesterov made a simple repair to all these transmissions. One time the British representative came up to Nesterov and asked him, “At which university did you study?” And Nesterov replied, “At the kolkhoz!”

The Sherman was light years better in this regard. Did you know that one of the designers of the Sherman was a Russian engineer named Timoshenko? He was some shirt tail relative of Marshal S. K. Timoshenko.

The Sherman had its weaknesses, the greatest of which was its high center of gravity. The tank frequently tipped over on its side, like a Matryoshka doll (a wooden stacking doll). But I am alive today thanks to this deficiency. We were fighting in Hungary in December 1944. I was leading the battalion and on a turn my driver-mechanic clipped a curb. My tank went over on its side. We were thrown around, of course, but we survived the experience. Meanwhile the other four of my tanks went ahead and drove into an ambush. They were all destroyed.

 

Dmitriy Fedorovich, the Sherman had a rubber-coated metal track. Some contemporary authors point to this as a deficiency, since in combat the rubber might be set on fire. With the track thus stripped bare, the tank is disabled. What can you say in this regard?

On the one hand this rubber-coated track was a big plus. In the first place, this track had a service life approximately twice that of steel track. I might be mistaken, but I believe that the service life of the T-34 track was 2500 kilometers. The service life of the Sherman track was in excess of 5000 kilometers. Secondly, The Sherman drove like a car on hard surfaces, and our T-34 made so much noise that only the devil knows how many kilometers away it could be heard. What was the bad side of the Sherman track? In my book, Commanding the Red Army’s Sherman Tanks, there is a chapter entitled “Barefooted”. There I wrote about an incident that occurred in August 1944 in Romania, during the Jassy-Kishinev Operation. The heat was fearsome, somewhere around 30° C. We had driven approximately 100 km along a highway in a single day. The rubber linings on our support rollers got so hot that the rubber separated and peeled off in long pieces. Our corps paused not far from Bucharest. The rubber was flying around, the rollers had begun to jam up, the noise was terrible, and in the end we had been stopped. This was immediately reported to Moscow. Was this some kind of joke, an entire corps had halted? To our surprise, they brought new support rollers to us quickly and we spent three days installing them. I still don’t know where they found so many support rollers in such a short time. There was yet another minus of rubber track. Even on a slightly icy surface the tank slid around like a fat cow. When this happened we had to tie barbed wire around the track or make grousers out of chains or bolts, anything to give us traction. But this was with the first shipment of tanks. Having seen this, the American representative reported to his company and the next shipment of tanks was accompanied by additional track blocks with grousers and spikes. If I recall, there were up to seven blocks for each track, for a total of fourteen per tank. We carried them in our parts bin. In general the American representative worked efficiently. Any deficiency that he observed and reported was quickly and effectively corrected.

One more shortcoming of the Sherman was the construction of the driver’s hatch. The hatch on the first shipment of Shermans was located in the roof of the hull and simply opened upward. Frequently the driver-mechanic opened it and raised his head in order to see better. There were several occasions when during the rotation of the turret the main gun struck this hatch and knocked it into the driver’s head. We had this happen once or twice in my own unit. Later the Americans corrected this deficiency. Now the hatch rose up and simply moved to the side, like on modern tanks.

Still one great plus of the Sherman was in the charging of its batteries. On our T-34 it was necessary to run the engine, all 500 horsepower of it, in order to charge batteries. In the crew compartment of the Sherman was an auxiliary gasoline engine, small like a motorcycle’s one. Start it up and it charged the batteries. This was a big deal to us!

For a long time after the war I sought an answer to one question. If a T-34 started burning, we tried to get as far away from it as possible, even though this was forbidden. The on-board ammunition exploded. For a brief period of time, perhaps six weeks, I fought on a T-34 around Smolensk. The commander of one of our companies was hit in his tank. The crew jumped out of the tank but were unable to run away from it because the Germans were pinning them down with machine gun fire. They lay there in the wheat field as the tank burned and blew up. By evening, when the battle had waned, we went to them. I found the company commander lying on the ground with a large piece of armor sticking out of his head. When a Sherman burned, the main gun ammunition did not explode. Why was this?

Such a case occurred once in Ukraine. Our tank was hit. We jumped out of it but the Germans were dropping mortar rounds around us. We lay under the tank as it burned. We laid there a long time with nowhere to go. The Germans were covering the empty field around the tank with machine gun and mortar fires. We lay there. The uniform on my back was beginning heating up from the burning tank. We thought we were finished! We would hear a big bang and it would all be over! A brother’s grave! We heard many loud thumps coming from the turret. This was the armor-piercing rounds being blown out of their cases. Next the fire would reach the high explosive rounds and all hell would break loose! But nothing happened. Why not? Because our high explosive rounds detonated and the American rounds did not? In the end it was because the American ammunition had more refined explosives. Ours was some kind of component that increased the force of the explosion one and one-half times, at the same time increasing the risk of detonation of the ammunition.

It is considered noteworthy that the Sherman was very well appointed on the inside. Was this true?

It was true. These are not just words! They were beautiful! For us then this was something. As they say now, “Euro-repair”! This was some kind of European picture! In the first place, it was painted beautifully. Secondly, the seats were comfortable, covered with some kind of remarkable special artificial leather. If a tank was knocked out or damaged, then if it was left unguarded literally for just several minutes the infantry would strip out all this upholstery. It made excellent boots! Simply beautiful!

 

In your book “Commanding the Red Army’s Sherman Tanks” you wrote that the 233rd Tank Brigade’s M4A2 Shermans were armed not with the short-barreled 75mm but the long-barreled 76mm main gun in January 1944. Wasn’t this a bit early? Didn’t these tanks appear later? Explain one more time which main guns were mounted on the Shermans of the 233rd Tank Brigade.

Hmm, I don’t know. We had very few Shermans with the short-barreled main gun. On the whole, ours had long-barrels. Not just our brigade fought on Shermans. Perhaps these were in other brigades. Somewhere in the corps I saw such tanks, but we had the tanks with the long barrels.

Dmitriy Fedorovich, there were personal weapons in each Sherman that arrived in the USSR, Thompson submachine guns (also known as the Tommy gun). I read that rear area personnel stole these weapons and that few tanks arrived in units still equipped with them. What kind of weapons did you have, American or Soviet?

Each Sherman came with two Thompson submachine guns, in caliber 11.43mm (.45 cal), a healthy cartridge indeed! But the submachine gun was worthless. We had several bad experiences with it. A few of our men who got into an argument were wearing padded jackets. It turned out that they fired at each other and the bullet buried itself in the padded jacket. So much for the worthless submachine gun. Take a German submachine gun with folding stock (MP-40 SMG by Erma -Valeri). We loved it for its compactness. The Thompson was big. You couldn’t turn around in the tank holding it.

The Sherman had an antiaircraft machine gun Browning M2 .50 caliber. Did you use it often?

 I don’t know why, but one shipment of tanks arrived with machine guns, and another without them. We used this machine gun against both aircraft and ground targets. We used it less frequently against air targets because the Germans were not fools. They bombed either from altitude or from a steep dive. The machine gun was good to 400-600 meters in the vertical. The Germans would drop their bombs from say, 800 meters or higher. He dropped his bomb and departed quickly. Try to shoot the bastard down! So yes, we used it, but it was not very effective. We even used our main gun against aircraft. We placed the tank on the upslope of a hill and fired. But our general impression of the machine gun was good. These machine guns were of great use to us in the war with Japan, against kamikazes. We fired them so much that they got red hot and began to cook off. To this day I have a piece of shrapnel in my head from an antiaircraft machine gun.

Did German aircraft inflict significant losses on your equipment? In particular, what can you say about the Henschel Hs-129?

Not every time, but it did happen. I don’t remember the Henschel; perhaps there was such an airplane. Sometimes we were able to avoid bombs. You could see them coming at you, you know. We opened our hatches, stuck out our heads, and instructed our drivers over the intercom: “The bomb will fall in front of us”. But in general there were cases when tanks were hit and set on fire. Losses from these attacks did not exceed 3-5 tanks in the battalion. It was more common for a single tank to be damaged or destroyed. We faced much greater danger from panzerfaust gunners in built-up areas. In Hungary I recall that I was so tired that I told my deputy to lead the battalion while I slept. I went to sleep right there in the fighting compartment of my Sherman. Around Beltsy they had dropped ammunition to us by parachute. We took one parachute for ourselves. I used this parachute for my pillow. The parachute was made from silk and didn’t let the lice in. And I was sound asleep! Suddenly I woke up. Why? I awoke from the silence. Why the silence? It turns out that attacking aircraft had set two tanks on fire. During the march many things were piled up on the tanks: crates, tarpaulin. The battalion had halted, shut off engines, and it had become silent. And I woke up.

Did you lock your hatches during combat in built-up areas?

We absolutely locked our hatches from the inside. In my own experience, when we burst into Vienna, they were throwing grenades at us from the upper floors of buildings. I ordered all the tanks to be parked under the archways of buildings and bridges. From time to time I had to pull my tank out into the open to extend a whip antenna and send and receive communications from my higher commander. On one occasion, a radio operator and driver-mechanic were doing something inside their tank and left the hatch open. Someone dropped a grenade through the hatch from above. It struck the back of the radio operator and detonated. Both were killed. Thus we most certainly locked our hatches when we were in built-up areas.

The primary defeating mechanism of HEAT (hollow-charge) ammunition, of which the panzerfaust was one type, is the high pressure in the tank, which disables the crew. If the hatches were kept slightly open, would this not provide some degree of protection? A special order was issued before our forces entered Germany.

This is true, but just the same we kept our hatches locked. It might have been different in other units. The panzerfaust gunners most often fired at the engine compartment. If they were able to set the tank on fire, like it or not the crew had to get out. And then the Germans shot at the crew with a machine gun.

What were the chances of survival if your tank was hit?

My tank was hit on 19 April 1945 in Austria. A Tiger put a round straight through us. The projectile passed through the entire fighting compartment and then the engine compartment. There were three officers in the tank: I as the battalion commander, the company commander Sasha Ionov (whose own tank had already been hit), and the tank commander. Three officers, a driver-mechanic, and a radio operator. When the Tiger hit us, the driver-mechanic was killed outright. My entire left leg was wounded; to my right, Sasha Ionov suffered a traumatic amputation of his right leg. The tank commander was wounded, and below me sat the gunner, Lesha Romashkin. Both of his legs were blown off. A short time before this battle, we were sitting around at a meal and Lesha said to me, “If I lose my legs I will shoot myself. Who will need me?” He was an orphan and had no known relatives. In a strange twist of fate, this is what happened to him. We pulled Sasha out of the tank and then Lesha, and were beginning to assist in the evacuation of the others. At this moment Lesha shot himself.

In general, one or two men were always wounded or killed. It depended where the shell struck.

How did you co-operate with the infantry during combat?

By TOE the tank brigade had three tank battalions of 21 tanks each and a battalion of submachine gunners. A submachine gun battalion had three companies, one for each tank battalion. We had this three-battalion structure only in late 1943 and early 1944. All the rest of the time we had two tank battalions in the brigade. Our submachine gunners were like brothers to us. On the march they sat on our tanks. They kept warm there, dried their things, and slept. We drove along and then stopped somewhere. The tankers could sleep and our submachine gunners protected our tanks and us. Over the course of time many submachine gunners became members of our crews, initially as loaders and later as radio operators. We divided our trophies equally: they with us and we with them. Therefore they had an easier time of it than ordinary infantrymen.

During combat they sat on the tanks until the firing started. As soon as the Germans opened fire on our tanks, they jumped off and ran behind the tanks, frequently protected by its armor from enemy light machine gun fire.

If it happened that the tanks were limited in maneuver and speed, did you maneuver your infantry or halt them?

Nothing like that. We did not pay any attention to them. We maneuvered and they maneuvered themselves behind us. There were no problems. It would have been worse for them if we had been knocked out, so let them run behind us.

Was the tank’s speed limited in the attack? By what?

Of course! We must been fire!

How did you fire, from short halts or on the move?

Both ways. If we fired on the move, the speed of the tank did not exceed 12 km/h. But we rarely fired on the move, only in order to incite panic in the enemy ranks. Primarily we fired from short halts. We rushed into a position, stopped for a second, fired, and moved ahead.

What would you like to say about the German Tiger?

It was an extremely heavy vehicle. The Sherman could never defeat a Tiger with a frontal shot. We had to force the Tiger to expose its flank. If we were defending and the Germans were attacking, we had a special tactic. Two Shermans were designated for each Tiger. The first Sherman fired at the track and broke it. For a brief space of time the heavy vehicle still moved forward on one track, which caused it to turn. At this moment the second Sherman shot it in the side, trying to hit the fuel cell. This is how we did it. One German tank was defeated by two of ours, therefore the victory was credited to both crews. There is a story about this entitled “Hunting With Borzois” in my book.

The muzzle brake has one significant shortcoming: a cloud of dust is raised during firing from a weapon thus equipped, giving away one’s position. Some artillerymen attempted to counter this, for example, by wetting down the ground in front of their cannons. What countermeasures did you employ?

You’re correct! We might have packed the ground and covered it with our tarpaulins. I don’t recall any special problems.

Were your tank sights blinded by dust, dirt, or snow?

There were no special difficulties. Snow, of course, could blind us. But not dust. The sight on the Sherman did not protrude. On the contrary, it was recessed into the turret. Therefore it was well protected against the elements.

Dmitriy Fedorovich, our tankers who fought on the British Churchills pointed out the weak heater in the crew compartment as a deficiency. The standard electric heater was inadequate for the conditions of the Russian winter. How was the Sherman equipped in this regard?

 The Sherman had two engines connected by a coupling joint. This was both good and bad. There were cases when one of these motors was disabled in battle. Then the coupling joint could be disengaged from the crew compartment and the tank could crawl away from the fight on one engine. On the other hand, there were powerful fans located above both engines. We used to say, “Open your mouth and the wind came out your ass!” How the hell could we get warm? There were such strong drafts of air! Perhaps there was heat coming from the engines, but I will not tell you that it was warm. When we halted, we immediately covered the engine compartment with our tarpaulin. Then it stayed warm in the tank for several hours; we slept in the tank. Not for nothing did the Americans give us fleece-lined coveralls.

Were there norms of ammunition consumption for the tank?

Yes there were. In the first place, we took one basic load (BK -boekomplekt -a full set of ammo. For example the IS-2’s BK = 28 shells. -Valeri) with us going into battle. We took an additional BK on the outside of our tanks during long raids. When I raced into Vienna, for example, my commander personally ordered us to take two BK: the normal load inside and the second on the armor. In addition, we carried up to two cases of trophy chocolate on each tank and found additional provisions for ourselves. We were “on our own”, so to speak. This meant that if we had to conduct a raid somewhere deep in the rear, we offloaded rations and in their place took ammunition. All of our wheeled supply vehicles were American 2 ?-ton Studebakers. They always brought the ammunition forward to the battalion.

There is one other thing I want to say. How did we preserve our (Soviet) ammunition? Several rounds covered by a thin layer of grease, in wooden crates. One had to sit for hours and clean this grease off the rounds. American ammunition was packed in cardboard tube containers, three rounds banded together. The rounds were shiny clean inside their protective tubes! We took them out and immediately stowed them in the tank.

What kind of rounds did you carry in the tank?

Armor-piercing and high explosive. There was nothing else. The ratio was approximately one-third HE and two-thirds AP.

Did the crew receive a concussion when a round hit the tank, even if it did not penetrate the armor?

Generally, no. It depended on where the round hit. Let’s say that I was sitting in the left side of the turret and a round struck near me. I heard this hit but it did not harm me. If it struck somewhere on the hull, I might not hear it at all. This happened several times. We would come out of an engagement and inspect the tank. In several places the armor would show an impact, like a hot knife that had cut through butter. But I did not hear the round impacts. Sometimes the driver would shout, “They’re shooting from the left!” But there was no overwhelming sound. Of course, if such a powerful gun as the JSU-152 hit you, you heard it! And it would take off your head along with the turret.

I want also to add that the Sherman’s armor was tough. There were cases on our T-34 when a round struck and did not penetrate. But the crew was wounded because pieces of armor flew off the inside wall and struck the crewmen in the hands and eyes. This never happened on the Sherman.

What did you consider the most dangerous opponent? A cannon? A tank? An airplane?

They were all dangerous until the first round was fired. But in general, the antitank cannons were the most dangerous. They were very difficult to distinguish and defeat. The artillerymen dug them in so that their barrels literally were laying on the ground. You could see only several centimeters of their gun shield. The cannon fired. It was a good thing if it had a muzzle brake and dust was kicked up! But if it was winter or raining, what then?

Were there cases when you did not see from your tank where the fire was coming from, but your SMG infantry did see? How did they guide you to the source of the fire?

Sometimes they pounded on the turret and shouted. Sometimes they began to fire in the direction with tracer bullets or fired a signal rocket in that direction. And then, you know, when we went into the attack, the commander often looked around from the turret. None of the periscopes, even in the commander’s cupola, gave us good visibility.

How did you maintain communications with your commander and other tanks?

By radio. The Sherman had two radio sets, HF and UHF [high frequency and ultra high frequency], of very good quality. We used the HF for communications with our higher commander, with brigade, and the UHF for communications within the company and battalion. For conversation inside the tank we used the tank intercom system. It worked great! But as soon as the tank was hit, the tankers first action was to throw off his helmet and throat microphone. If he forgot and began to jump out of the tank, he would get hung up.

#48 Jungle Tanking: The Sherman Saw Combat In Almost All Terrain, Including The Steaming Jungles Of The Pacific.

Jungle Tanking: The Sherman Did Just Fine As A Jungle Killing Machine

Sad_Sack_1st_caption

Conventional wisdom often states, Jungles are no place for tanks, but that wisdom is wrong. It is very difficult to operate a tank in the jungle, that is true, but that doesn’t mean it can’t be done. In many cases it requires the close work of heavy engineers and their bulldozers.  In at least one case engineers had to put in a corduroy log road to get the tanks up to the fight when the Marines used them on Cape Gloucester. When a tank can be brought up though, when used correctly, it was a very useful tool in destroying enemy bunkers and strong points that could not be flanked.

Another Marine M4A1 on Cape Gloucester, this one made by (Pacific Car & Foundry) West Coast Best Coast Baby!

Tanks have to be used in a different way than they would in just about any other terrain when fighting in the jungle, and more so than any other terrain, are dependent on their infantry support to protect them and be their eyes. They also cannot be employed in large numbers, fighting in the jungle is a very up close and personal affair, and from two to six tanks are all that are needed or can really be employed.  In most cases it will only be two or three, because most jungle fighting is limited to certain paths due to terrain restrictions.  If the area was wide enough, a tank was only behind a bulldozer in off road ability, but large trees and rocks will stop any tank.

The Tank could be useful for clearing some of the jungle terrain, through the use of its machine guns, cannon with canister rounds or HE, and even its tracks.  It would take a fairly large tree to stop a tank, the bigger the tank, the larger the tree would have to be, and the tracks are very good at tearing up underbrush.  In some cases tanks were used to pull loaded trucks up roads normally impassible due to mud.  They could be used to haul in supplies to troops and in some special cases used to retrieve wounded troops pinned down by enemy fire, by driving over them and pulling the wounding in through the bottom escape hatch.

Were calling this M4 Composite Hull on Okinawa, named “Aida” with the 763rd TB (thanks to Russ Amott for the info on this photo)

To successfully employ tanks a thorough recon of the area the tanks are going to operate in was needed.  A specific set of objectives, preferably, ones that could be seen from the jumping off point were needed to effectively use tanks, or they just got in the way.  With established objectives, specific infantry squads would be assigned to work directly with individual tank, to baby sit it and keep enemy infantry away.  The platoon leader would be encouraged to either ride on the tank his men were protecting, or stay very close to it so he could talk to the tank commander. The tanks would hold back with their protecting infantry, until the leading grunts made contact, then as needed they would move slowly forward and engage targets pointed out by the grunts.  Moving slow and staying with the men protecting the tank was very important, if they fell behind or got run off by flanking fire, the tank became very vulnerable to close infantry attack.  This is why the platoon leader staying close to the tank was important, so it could be told to start backing up the fire was too heavy.  If an attack failed, the tanks were advised to never attack over the same path, especially if the Japanese had time to bring up AT guns or mines.

Marines supporting an M4A2, in almost jungle, or jungle after lots of shore bombardment.

The pace of these attacks was purposely slow, they needed to make sure they were not bypassing an AT gun or tank killer team hiding in the brush.  Various methods were used, from hand signals to tracers and smoke to designate targets to the tank.  Smoke worked ok, but someone on the phone on the back of the tank telling the TC exactly where to look worked the best.  Once the bullets were flying the tank crews buttoned up and would not open up until asked by the supporting Doughs, or the intense part of the fighting was over.  Sometimes the tanks would need to be given a break in very hot weather, operating at low speed could cause overheating and vapor lock, and was hell on the crews too.  In the tropical heat, the interior of an M4 was not a pleasant place to be.

M4_Guam_01_44

Once the objectives were achieved for the day or the attacks were stopped, the tanks pulled back far enough behind the lines to refuel, repair and, rearm the tanks. They would also take out as many wounded men as they could carry on their way to the rear. In the morning they may haul extra ammo and other supplies forward to the units who held the line.  Tanks, unless under the most dire circumstances were not used in the line at night, or used in night attacks.  Tanks, blind enough during the day, are so blind at night they are a threat to everyone around them, friend or enemy in the jungle.

These M4 Composite Hulls were  lost on Guam, near Yigo, after they got to far ahead of the Infantry. (Another photo caption save by Russ Amott!)

The Army and Marine learned a lot of lessons about employing tanks in Jungle terrain, they recorded and disseminated these lessons in the very interesting: Combat Lessons, The Rank And File, What They Are Doing and How They Are Doing it. This was a series of nine, 50 to 90 page pamphlets, put out by the  DOD and sent out to all the troops I have 8 of the 9 hosted in the downloads section, and they are all interesting reads,  they do not cover Armor exclusively, or even in every issue, but they are still a very interesting look at how the US Army and Marines worked during WWII.  When the Sherman was employed using the lesson the Army and Marines learned on the job, they proved to be a crushing and very hard to deal with part of the Allied Arsenal in use against them. The Japanese really had few options in dealing with a Sherman once it was in the fight, the rare 47mm AT gun, hard to employ in heavy jungle, magnetic mines and suicide squads, and the occasional oddball tank trap were the only tools in their arsenal that could deal with the Sherman and none of these was as good as the basic Panzerfaust or German Pak 40 75mm AT gun. The Japanese tanks were so bad they are not worth mentioning in this section.

Here’s a short video of an M4A4 driving around.

The M4 105 Dozer, a video dedicated to just it! bonus includes Sherman drifting! They look like they are having so much fun in this video! Well until they bust it! This video is a BLAST!!!!

Shermans and a M31 ARV gutted and made to look like a M3 Lee again.

This was a Normandy Memorial day in 2013 I think. In this video, we see an M4A1 75 start up and then drive off, almost stalling.  Then later we get to see an M4A1 76w driving around.  Interesting how close they let people get to moving tanks.  Parked nextr to it is an M10 tank destroyer.

This is another Normandy D-Day Memorial, 2014. The Video starts off with an mid production small hatch M4A1 75, with a later production M10 behind it and then an M18.  After that an small hatch M4a2, and then the Fury M4A2 76 HVSS tank.

#14 Main Guns: Things That Go Boom, Some Bigger than Others, but None Bad

Main Guns: The Sherman Mounted Six Different Guns, But Not On All Versions, NOW WITH GUN DATA SHEETS!

The Sherman tank and its chassis was host to a variety of guns.  Most had the M3 75mm gun, or the M1A1 76mm gun, but many were also equipped with the British 17 pounder, the M3 90mm, 3 inch AT gun and the M2/M4 105mm howitzer.  I will cover each below.

The M3 75mm gun: When it first saw Combat, it was a Great Tank Gun

The M3 75mm gun was a great tank gun for the time the Sherman was first introduced to combat, and was based on a well-liked WWI French field gun. When it first saw combat it could punch through any German tank it faced, from just about any angle. It’s a myth the Sherman was designed to only support infantry, though it’s primary role was not anti-armor, it was still designed to face other tanks.  The gun worked well in the infantry support role as well, with an effective HE and WP smoke round, and a canister round. This gun had a very high rate of fire in the Sherman (20rpm) and was mated with a basic stabilization system. This system did not allow shooting on the move accurately, but did allow the sights and gun to be put on the target faster when the tank came to a stop to shoot. No world war two tanks could shoot on the move with a real chance to hit even a stationary tank sized target. With a twenty round a minute rate of fire, the Sherman could pump out a lot of HE in support of the infantry, and it was not unheard of for the tanks to be used as artillery. The Sherman tank was equipped with all the gear to act as artillery if needed and was a regular occurrence in the MTO, less so in the ETO.

M4A2 75

Sherman tanks with the 75mm gun carried between 104 and 97 rounds of main gun ammo. Only 10 to 15% of this ammo was AP, that’s how rare other armor was, HE would make up the majority of the rest of the load, with maybe another 10 to 15% being WP smoke, since this was also a somewhat destructive shell, because it caused fires and WP when it landed on a person was hard to put out. There was also a canister shell, but I think it was only used in the PTO.  The rate of fire on the gun is a little misleading, since depending on the Sherman, you would have between 6 and 12 ready rounds, more on the very early Shermans with ready rounds around the base of the turret basket.  Once the ready rounds were fired, and often, the ready rounds are kept in reserve anyway, to deal with unexpected threats.  Wet Shermans had an armored 6 round ready box mounted in the turret, the rest of the ammo was in armored boxes under the floor. Most wet tanks had a half turret basket or none at all. This was a problem common on pretty much all tanks.

m4a3 75 m70f reticle

The M3 75mm gun was so well liked, the British essentially ended up converting many of the QF 6 pounders to fire the same round, fired with basically the same ballistics, with the advantage of not needing to modify the current tanks mount.  The WF 6 pounder was a better AT gun, but, it’s HE round was not very good. The M48 HE round used by the m3 75mm had 1.5 pounds of TNT inside, and since the Sherman could fire them fast, and the shell was fairly handy, it’s easy to see why the gun was good at infantry support.  It really only lacked the ability to pen the frontal armor of the German Tiger and Panther, but those tanks were rare enough, or easy enough to get side shots on, the 75 did the job, and did it the whole war, since the 76mm armed Shermans never totaled more than 53% of the Sherman force in Europe. The M3 75mm gets a lot of flak thrown at it by ignorant people who think it was a low velocity gun that could not penetrate armor. These people must be confusing it with the German KwK 37 L/24 75mm gun that armed the first versions of the Panzer IV.

The M1/M1A1/M1A2 76mm gun: Made by Oldsmobile, It was Not a Great Gun, but Did the Job

The M1 series of 76 mm guns went into production before the US Army had any idea of German heavy tanks, or the Panther. They were just looking ahead, to keep the Sherman as good a combat weapon as possible, and to stay ahead in the arms race.  They had the 3 inch AT gun on hand, and had used it in the M6 and M10, but it was really to bulky to work in a medium tank turret.  The Army decided to design a gun with the same ballistics, but in a much lighter, and less bulky package, in doing so the M1 gun was born.  The gun overhung the front of the Sherman a lot so the Army decided to shorten it over a foot. It still seemed to match the ballistics of the 3 inch AT gun though; guns with the shorter barrel were designated M1A1 guns.  The first three hundred of so guns produced by Oldsmobile lacked muzzle brakes or the threads to install them. Gun’s produced after that had the threads and a protective cap over them so a brake could be installed later. The final variant of the gun was the M1A2, installed in late production 76mm Shermans, this gun always had the muzzle brake, but had a slightly different barrel, with a minor change to the rifling twist.

37936_3070533d
M4A1 76W with unthreaded M1A1 gun

Much of the later large hatch hull tanks were produced with a larger turret to accommodate the M1 family of 76mm guns. This turret came on M4A1s, M4A2s and M4A3 tanks.  The M1A1 on the early tanks, like the M4A1 76 w tanks used in Operation Cobra, came without muzzle brakes. When firing during dusty -conditions the view of the target would be obscured by dust stirred up from the guns blast, the fix for this was for the commander or another crewman to stand away from the tank and talk to the crew over the intercom, via a long wire, and correct the shots onto target. Not a great fix…The final fix was muzzle brakes; it took a little while for supply to catch up with demand but they were showing up on Shermans in Europe by late 44, and by March they seemed to be in stock, and showing up on tanks that had the protective cap before.

Another problem was the gun was not a huge improvement over the M3 75mm as a tank killer, and was not as good as an HE thrower. As mentioned before, several tank divisions didn’t want the improved Shermans at first. The penetration problem would be partially solved with HVAP ammunition, but by the time it was common, German tanks to use it on were not.   Post war, ammunition would be further improved and there would be no shortage of HVAP ammo in Korea, so the US Army would soldier on with the gun, in its final improved form, the M1A2.

The M1 series of guns were also stabilized when installed in the Sherman, but it was the same system used with the 75mm gun, offering limited advantages. The Nazi Germans never fielded a stabilization system of any kind on their tanks. Tanks with the M1, and M1A1 guns carried 71 main gun rounds in wet storage racks in the floor, with an armored 6 round ready rack on the turret floor.

The M3 90mm Gun: The Most Powerful AT Gun the US used During the War.

The US M3 90mm tank gun started out life as an AA gun, a very good AA gun, unlike the very overrated Flak 18/36/37.  As the AA gun was developed, it’s mount gained the ability to be used against ground targets, with up to -10 degrees depression.  The ballistic performance on the gun was good, but what really made the AA gun shine was the AA gun system that incorporated Radar, and proximity fuses, sci-fi tech to the Germans, but pretty typical American technology for the time, it was the best land based AA gun system of the war.  Contrary to some claims, it was pretty rare for US 90mm AA guns to be used in the direct fire role. The US Army was rarely desperate enough to have to resort to such tactics.

M36 with M3 90mm

When the US Army started looking into a bigger AT gun than the 3 inch, the M1/M2 90mm AA gun was a natural choice.  The tank mounted weapon would be designated the M3, and with a barrel threaded for a muzzle brake, the M3A1. When tested against the British 17 pounder gun, the M3 had slightly inferior performance, but was more accurate. The US Army preferred the 90mm over the 17 pounder for various reasons, the biggest being it didn’t have scary flashback out of the breach on firing, making it seem like a somewhat shoddy design. The 90mm M3 would soldier on the in the M26/46 tanks,  but would be replaced by improved 90mm guns on the M47 and M48.

reticle m76f

As a dual purpose tank gun, the M3 90mm was good. It’s rounds were not to big for one man to handle. It had good AT performance, and a more potent HE round than the M3 75mm gun. When installed on the M36 Tank Destroyer, it was able to deal with the rare heavily armored German threat, if the regular Shermans hadn’t already killed it by the time the M36 got there. Since the gun was not overly hot, it didn’t wear barrels out fast, so it could still be used in artillery role.

The 3 Inch AT gun: An Old AA Gun Finds a New Use

The 3inch AT gun started out life as a AA gun. It was still being used as one for the first half of the war.  It was a natural choice as an AT gun since it was being replaced by the M1/2/3 90mm AA gun system. The gun was large, heavy and bulky, and the M10 tank destroyers turret had to be rather large to fit it.  They were also able to fit it in the T1/M6 Heavy tank, but it was clear it needed a redesign to fit in a smaller turret like the regular Sherman. This ultimately lead to the M1A1 gun discussed above.

2nd-french-armored-div-m10-halloville-france-nov-13-44570
M10 with three inch gun

There was also a towed AT gun version of this weapon, it was generally not well liked. It was too big to move around easily by hand, hard to hide, and didn’t have great pen to work well as a fixed gun. At one point in the war, nearly half the Tank Destroyer Battalions were towed, and equipped only with the towed guns and trucks to move them. These TD battalions had little luck, and some really got clobbered in the Battle of the bulge.

Ultimately this guns use was more about taking unused guns on hand and getting a decent AT weapon out the door fast, by using them for this new purpose. They were not perfect, and as towed weapons, even really good, but on a mobile platform like the M10 or even the M6 heavy tank they did the job well enough.

The M2/M4 105mm Howitzer: Artillery in a Sherman Package

30137195
M4A3 105 HVSS tank

The US 105mm M2/M4 howitzer was the biggest gun installed in the Sherman, the versions of the Sherman with this gun were developed to replace the M7 Priest, but never fully did so during WWII.  They were used in the same role, or in limited direct support roles. These tanks did not have a stabilized gun or wet ammo racks, but did have the large hatch hull. All 105 Sherman tanks, either M4 (105)s or M4A3 (105)s were produced exclusively by Chrysler. 105 tanks carried 66 rounds of main gun ammo, in dry ammo racks.

Sherman tanks equipped with the 105 often found themselves pooled with the others from the three companies of a battalion, with the two from the battalion HQ, so the Tank Battalion could have their own mini 105 battery on call. When working with their assigned company, they were often held in the back, and supported the gun tank platoons with indirect or direct fire. Use in direct fire support would be the rarest use for them, but it did take place.

The 17 pounder gun: 76.2mm of British High Velocity Boom Boom

The 17 pounder was developed to replace the 6 pounder, it was clear the 57mm 6 pounder wasn’t going to be able to handle tanks with thicker armor, but it stayed surprisingly relevant late into the war.  The 17 pounder started development in the final months of 1940 and was going into prototype testing in late 1941.  The first few AT guns were made by slapping the gun onto the 25 pounder carriage called the 17/25 pounder, and some were shipped to North Africa, to counter the supposed Tiger threat. The full production QF 17 pounder AT gun was available by the Italian Campaign.

1405_3065484
American Test Firefly with 17 pounder

The main reason the gun was a better AT gun than the US M1A1 gun was the round had a lot more propellant behind the projectile and then the Brits came up with the super velocity discarding sabot round. This new round had very good penetration, but had some serious accuracy problems.  The accuracy problems with the SVDS ammo were not fully solved until after the war.  The gun was intended for tank use, but the British Tanks meant for it had to many developmental problems, and were not going to be ready by Normandy landings, so the Sherman Firefly was born. See its own section for more info on these Shermans.

#2 Basic Sherman History: The Previous Tanks That Led To the Best Tank Of The War

Basic Sherman History: The combat RV, AKA the M3 Lee

To really know why the Sherman was designed the way it was, you have to know about the M3 Lee. The M3 was the predecessor of the M4. It was based on M2 medium, the US Army’s only foray into modern medium tank design at the time, and modifying it was the fastest way a tank could be designed with a 75 mm M3 canon fitted. The US lacked the jigs to make a turret ring big enough for a turret to house a gun that large; the Lee went into production while the turret ring problem was being solved, by mounting the gun in a sponson mount, and beefing up the rest of the tank a bit, and removing a machine gun or two. It had become clear to the US Army that the 75mm canon would be needed based on feedback from the British, and observations of how the war was developing in Europe.

One of the reasons for the reliability of the M4 design was the use of parts that started their design evolution in the M2 medium and were improved through the M3 production run. Over the life of M3 Lee and M4 Sherman the designs were continually improved as well, so a final production, M3, or M4A1, bared little resemblance to an initial production M3 or M4A1, yet many parts would still interchange. This is one of the reasons the Israelis had so much success updating the Sherman to the M50 and M51, these tanks used early small hatch hulls, that never had HVSS suspension installed, but the hulls took the updated suspension with few problems.

When the Lee went into production, though it was far from an ideal design, it still outclassed the German and Italian armor it would face, and its dual purpose 75mm gun would allow it to engage AT guns with much more success than most of the British tanks it replaced. It was reliable, and well-liked by its users, and produced in pretty large numbers. When the British got enough Shermans, the Lees and Grants were sent to the Far East and saw use until the end of the war fighting the Japanese. The Lee excelled at infantry support, since it had a 37mm canon that could fire canister rounds, along with the 75mm gun and a lot of machine guns. Many of these Lee tanks ended up in Australia after the war.

Another universal complaint about the Lee was once all the guns were firing, there was not enough ventilation, and the crew if forced to stay inside for long periods operating the weapons had even been reported to pass out on occasion. The Sherman would all more armored ventilators, but still not enough, until the later versions for the best in crew comfort.

Lee variants:  The Combat RV

M3 Lee being used in training pre WWII.

M3 Lee: The First Combat Ready American Medium

This was the first version of the tank and used a riveted hull with the R975 radial engine powering it, the suspension and tracks were very similar to the M2 medium.  Early production tanks had an M2 75mm instead of the improved M3 gun. These tanks had a counter weight mounted on the shorter barrel. All Lees had a turret with 37mm M5 gun. The early production version had two hull mounted, fixed .30 caliber machine guns, another mounted coaxially with the 37mm gun, and another in a small turret, mounted on top of the 37mm turret for the commander.

They built nearly 5000 of these tanks. The M3 was improved on the production line with things like removal off hull machine guns, and hull side doors. The mini turret mounted M1919A4 was not a popular feature, and was hard to use, but it remained on all Lees, and were only deleted from the Grant version produced exclusively for the British.

If this version had a major flaw, it would be the riveted armor plates could shed rivets on the inside of the tank and these rivets bounced around like a bullet. This was bad for the crew, but, rarely resulted in a knocked out tank. A field fix for this was welding the rivets in place on the interior of the tank.  Most of the M3 Lees produced went to the British. 4924 produced.

I’ve read other sources that said the Lee and Grant tanks did not shed rivets and this was a myth.

 

M3A1
Cast M3A1 Lee, note the curved cast upper hull

M3A1 Lee: A Lee, But with a Cast Hull

This version of the Lee had a cast hull, and R975 radial power. It was really the same as the base Lee in most respects including improvements. 300 built. These cast hull tanks have a very odd and distinctive look. They look almost like a M3 Lee was melted. This hull casting was huge and more complicated than the M4A1 casting. Most of these tanks were used in the United States for training. 300 produced.

 

M3A2 Lee with a welded hull.

M3A2 Lee:  A Lee, Only Welded

This Lee had a welded hull and the R975 powering it. 12 built. This version was more of a ‘proof of concept’ on welding a hull than anything.

 

M3A3 Lee: A Lee With The 6046

Another welded hull but this one powered by the GM 6046 Twin Diesel. 322 built, like the base Lee, with the same improvements. This is the first vehicle the 6046 was used in, and most of the bugs were worked out on this model. 322 built. Some of the problems with the motor were air cleaners that needed cleaning to often, and a complicated oiling system.  Crews preferred it, when running right, to the R975.

 

M3A4 Lee: A Lee With The Fantastic A-57 Motor

This version had a riveted hull and was powered by the A-57 multibank motor. This motor was so large the hull had to be stretched for it to fit; it also required a bulge in the top and bottom of the hull to fit the cooling fan. They also had to beef up the suspension, and the suspension units designed for this would become standard units on the Sherman. This would be the only version of the Lee with the improved bolt on offset return roller VVSS, otherwise this tank was very much like the base M3. 109 built. This motor’s bugs were worked out on this tank and would go on to power a large chunk of Sherman production.

M3A5 Grant: A Diesel Lee, Made For the Brits, with a New Name and Turret

Another welded hull, powered by the GM 6046 Twin diesel with a new bigger turret to house British radios. 591 built. This new turret deleted the small machine gun turret on the roof of the 37mm turret. This version was used only by the British. The famous General Montgomery’s personal M3A5 is on display in England, at the Imperial War Museum in London. 591 produced.

The majority of Lee and all Grants saw service with the British, and many Lees went to the Soviet Union. They were generally well liked by both nations and more reliable than most of its British and German contemporaries.  These tanks were better than the enemy tanks they faced until the Germans up gunned the Panzer IV series. When they were replaced with M4s of various types the M3 were shipped to the Far East for use in Burma and New Guinea, where they would be used until the end of the war. The Japanese had no tank that could take on a Lee, let alone a Sherman. Using soldiers as suicide bombers, and mines still worked though, there was also a pesky 47mm AT gun, but it was rare. The 37mm gun firing canister rounds was a nice to have in thick vegetation.

M3_Lee_Medium_Tank_Prototype_At_Aberdeen_Proving_Ground

They saw limited use in the US Army’s hands some seeing combat in North Africa, because US combat units lost their Shermans to replace British losses, and a few were used in the PTO. The Sherman owes it success to the lessons learned producing the Lee and from its use in combat.  The 75mm gun and automotive systems, even the more complicated ones, would be perfected in the Lee and re-used in M4, and the Sherman only had one motor not tested in the Lee first.  Many of the Lee variants were produced at the same time and the numbering system was more to distinguish between hull and engine types, not to model progression like in aircraft, and other tanks.  This practice was carried over to the M4 series as were all the engines used in the Lee.

20090614m3-lee1

Many people familiar with the way the United States designated aircraft during the war figure it was carried over to tanks and think an M3A1 was an improved M3, and an M3A2 was an improved A1. This is not the case, as many of these versions were produced at the same time, and they all received the same sets of improvements, though some factories took longer to implement things than others though.

The M4A1 went into production as soon as the jigs for the turret ring were produced and ready to be used. Production actually started on the cast hull M4A1 first, with the welded M4A2 following right behind it. Like the Lee, there were many version of the Sherman in production at the same time. There are many photos of Lee’s coming off the production line, with Shermans in the line right behind the last Lee, so there was no real gap in production between the two tanks at most of the factories.
