Tanks in motion: Sherman Tanks on Film, Either Modern Restorations or Period Videos.
Here is an older video of an M4A1 that was restored and had new tracks installed. They really put this tank through the paces and it’s worth it even if the music is a bit dated.
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.

A video of a restored M4A1 driving in circles firing off its main gun, I’m sure modified to fire on propane as a noise maker.
A very long video, POV from the co drivers spot, on a restored, small hatch M4A1.
Here is a video of a restored Firefly Vc, a Sherman M4A4, with the a working A57 multibank motor, getting new tracks. This may not look tricky, but these men are all risking losing fingers or toes, or worse, if someone messes up.

The US Firefly: Yeah I said US Firefly, They Made Some But None Saw Combat, And They Were Unique And Not Like The Brit Ones.
Before the Normandy landings, the British had offered the US up 200 guns a month, if they were interested in the 17 pounder gun. Their rearmament program was well underway and would have enough Firefly tanks ready to go by D-Day. The US was not interested for a variety of reasons. The 76mm M1A1 and M3 90mm gun programs were well underway. Vehicles that used the guns were in the pipeline, even if there wasn’t much demand from the field yet. They did not want to complicate the supply situation with another tank ammo type.
Another reason was the 17 pounder did not really impress the US officers who witnessed test of it. It had both a large muzzle-flash and breach flashback, that hinted to them of a poor design. The efforts to convince the Americans of the errors of their ways went dormant along with the program. It wasn’t until the Ardennes offensive, when the US faced some heavier German armor, and in larger numbers than thought to be possible, that the program came back to life.
Conversions of 75mm armed US Sherman took place starting in March of 45. The US conversions were different in a few ways. The armored box on the rear of the turret was a little bigger to fit US radios, and the M2 machine gun brackets were welded to the end of the radio box. The tanks chosen for the conversions were all M4s and M4A3. It’s possible some large hatch final production Shermans with all the improvements were a part of the 160 to 200 that were converted before the program was suspended.
No one has come up with what happened to the tanks, and it seems like none survived. None were ever issued to US units, it’s one of those little mysteries lost to the archives and or time.
The Firefly: The Best AT Gun Installed On The Sherman, But Maybe Not The Best Overall Version Of The M4 Series.
The Sherman Firefly is often touted as the best version of the Sherman. This is a very shallow view of the tank; a tank is not just about AT performance alone. Let’s talk about the name, the Firefly was just a nickname, some say given by American testers because there was so much flash at the breach of the gun on firing, some claim it was just based on muzzle flash. Much like the Sherman naming mystery, it doesn’t really matter, it’s the commonly used name now, and if you just called them the Sherman IC, Sherman IC Hybrid, and Sherman Vc, no one but a total Sherman geek would know what the hell you were talking about. But everyone with a little Sherman history or WWII history under their belt should have heard of them called a Firefly so that’s what we will do here while explaining the nomenclature and how to identify the various models.
The Firefly came about because the British wanted to get a 17 pounder into a tank, and the homegrown ones planned to have it, were having issues. The 17 pounder, a 76mm anti-tank gun, had to be extensively redesigned to work in the Sherman 75mm turret, the AT gun versions recoil system was too long to work in a 75mm gun turret. They redesigned it, putting the recoil mechanism on both sides of the gun instead of the top. The gun was also rotated so it could be loaded from the left. The firefly version of the 17 pounder gun was specific to the Sherman gun mount and could not be used on an AT gun or vice versa.
They also had to cut a hole into the back of the turret, to mount the radios, in a new armored box, because the gun still had to recoil into the radio bustle at the back of the turret. The armored box also worked as a counterweight for the longer barrel. They also eliminated the co-drivers position and put a cast armored plug over the gun port. The co-drivers space was filled with ammo since the 17 pounder ammo was longer than the 75mm ammo it took more space. They also had to eliminate the gun stabilizer to fit the gun.
The 17 pounder gun had excellent armor penetration, in particular with APDS rounds, standing for armor piercing discarding sabot, but these rounds had very inconsistent accuracy. The problem that caused it was not worked out until after the war. At the combat ranges in the ETO and MTO, the APDS, worked ok, but the closer the better. The gun also lacked a decent HE round until after WWII ended when they came up with a system that used a smaller propellant charge for the HE rounds and a new set of marks on the tank’s sight for the lower velocity rounds.
The Firefly in a generic sense is easy to identify, you look for a 75mm gun turret, with a much longer gun with a ball-shaped muzzle brake. The turret will also have a loaders hatch and an armored box on the rear. From there, you have to look at the details, but it’s easy enough.
Sherman Ic Firefly: The Rarest Firefly
This is the Firefly based on the Sherman I or the M4. The lower case C after the Roman numeral designates the tank is armed with a 17 pounder. An M4 is a welded hull tank powered by an R975, so you look for the grate free engine deck, with the big armored flap covering an air intake. Or, if the tank is welded, and does not have large spaces between the bogie assemblies, then it’s an Ic Firefly.
Sherman IC composite hull firefly: The Second Rarest And Most Comfortable
This version is based on the M4 composite hull; the version had a cast front hull, and a welded rear hull. It looks almost like an M4A1, but the rear and sides of the tank are all flat surfaces, just like a regular M4, the other difference is these tanks had the improved large hatch hull. They would be the most comfortable version of the Firefly for the driver. These tanks were probably the last firefly’s built as well since the composite hull tanks were some of the last 75mm Shermans produced. The British were not given any of the 75mm M4A3 tanks so none were converted. One final advantage to this version from an ease of conversion point of view is the composite hull tanks came with a loaders hatch already built in, so it saved time because they didn’t have to cut and fit one. Some of these tanks also had all around vision cupolas, so it’s possible a few made it onto fireflies.
Sherman Vc Firefly: The Version Powered By The A57 Motor, and Also the Most Common Firefly, But The Motor Makes It The Coolest.
This version was based on the M4A4. These tanks are the “long hull” Shermans with the wide gaps between the bogie assemblies, and it has the distinctive bulges to the engine deck and lower hull. These hull features, with a firefly turret and gun, is more than enough to identify it as Vc. This Firefly type was powered by the mighty A57 multibank. The Wiki on the Firefly is trash; don’t go crawling around trying to see if the lower hull has rivets when most of the M4A4 production run had welded lower hulls. This may have only been a dubious way to identify an M3A4, you know if you missed it being almost a foot longer with huge gaps between the wheelsets and the bulges on the top and bottom.
This was the most common version of the Firefly since it was the Brits most numerous lend-lease Sherman. They got refurbished training A4s from the US and took as many of these them as they could because the production of 75mm Shermans had been drastically cut back and production of the M4A4 had been suspended.
Demand for the Firefly dropped off late in the war. They had produced enough that just about all the commonwealth nations the British supported received them. The Brits were able to put two Fireflies into most of their tank platoons, just as German armor became so scarce they didn’t really need them. By the end months of the war, the Firefly may have been more of a liability, than useful.
If you compare the Firefly to the upgraded M4A1 76w, you will see it really isn’t the best Sherman by any measure but raw gun penetration. We’ll use the composite hull Ic in the comparison since the same motor powered these tanks, and the composite hull had a very large casting for its front hull, making this as close to a second gen Sherman as the Firefly could get. Yet the composite hull tanks were produced early enough, they did not get wet ammo racks. They did get the armored ammo racks, but they really only offered protection against fragments lighting the ammo off.
This fix did not work nearly as well as the wet ammo racks on the M4A1 76, and other fully second gen Sherman tanks got. The main advantage was having the ammo lower in the tank, below the bottom of the sponsors, and encasing it in water jackets. It was found the most benefit came from the change in location, and the liquid part was discontinued post-war. The wet ammo rack second gen Shermans were amongst the safest WWII tanks to be a crewman on.
Now on to the turrets, the M4A1 76 tank has the improved T23 turret. These turrets came with the all-around vision cupola, a loaders hatch, and the 76 M1A1 gun, with a 30cal co-ax. The turret was designed around the gun, and was nice and roomy, offering relative comfort and ease of movement to the crew, allowing the gun to maintain the 20 round a minute rate of fire the 75mm gun had. It had better armor than the 75mm turret. The fireflies all used a modified 75mm gun turret, and even after redesigning the gun, the 17 pounder took up a lot of space and recoiled into the bustle, where the radio used to be. This made for a cramped turret, and a slower reload time. The T23 turret is better, and it’s a shame the Brits would have had to redesign the 17 pounder gun again to fit one into it.
At first glance, most people when they compare the M1A1 gun and the 17 pounder conclude the 17 pounder is ‘better’ based on its armor pen. This doesn’t take into account the other factors that make a good tank gun. In WWII, tanks faced other threats far more often than tanks. For the forces facing the United States in particular, tanks were never overly common and got rarer as the war went on. What Shermans faced most often, and what killed them most often was AT guns and infantry with AT sticks. The 17 pounders lack of HE round during the war, along with its lack of a bow machine gun, really hindered the Firefly in the infantry support role. The M1A1 didn’t have the best HE performance, but it was still adequate. It had enough AT performance to handle the PIV, Stugs and various TDs it would face. Including the cats, the M1A1 did not have the best balance of AT/HE performance, but it would get the job done, and as the war came to a close HVAP ammo, that really helped the guns AT performance, become increasingly available. The M1A1 also had a very big performance lead in rate of fire; double that of the 17 pounder.
When you take all these factors, it is clear the 76mm T23 turreted second gen M4A1, A2 and 3s were all better tanks than the Firefly, of any model. The reasons for this are the second gen Shermans all had wet ammo racks, and along with all the other minor improvements that came with the second gen Shermans. The 17 pounder gun would eventually get a good HE round, but not during the war, so the dual purpose us M1A1 gun is clearly a better choice for a general use medium tank.
I won’t go so far as to say the British should not have produced them. Since the Brits faced the majority of the German heavy armor in Normandy, a pure AT tank was more useful for them, and that’s why they built them. I’ve read in more than one place that the Germans always tried to kill off the fireflies first, and the firefly units used a cool paint scheme on the gun barrel to make it seem shorter to help hide the fireflies, but I’ve never seen it confirmed from the German side. These tanks were potent enough, killing the famous Nazi tank “Ace” Michael, the Nazi punk, Whitman, when he foolishly trundled by himself into their guns.
I find it amusing the most mechanically complicated Sherman was turned into the best pure AT Sherman by the Brits and was still more reliable than any Nazi tank. It may be a tad overrated, but it did exactly what it was designed to do, without compromising the reliability of its base platform. That makes it a smashing success and it gave the Brits a capability their American cousins lacked until much later in the war. It did so well, the Brits offered to convert some, and there was an abortive program that petered out because army ordinance thought the M1 gun would be good enough. During bulge hoopla, the program was revived, but this was short-lived, and none of the American Firefly tanks were issued to troops.
