#49 The Tank Divisions: US Armored Divisions

The Armored Divisions: The US Armored Divisions, What They Were and A Brief History Of Each One.

There were two types of US Armored Division during WWII.  The Light type and the Heavy type, I will detail out the differences between the two below. Armored Divisions were not meant to be assault troops, that was left to the Regular Infantry Divisions, the Armored Divisions were meant to rush through an breakthrough and romp and stomp as far into the enemy’s guts as they could, hopefully taking key objectives and cutting off large amounts of enemy troops.

A light US Armored Division was made up of three Tank Battalions, three Armored Infantry Battalions, and three Armored Field Artillery Battalions. These were broken up into three Combat Commands, A, B, and R. Each of these had a Tank Battalion, an Armored Infantry Battalion, and an Armored Field Artillery Battalion and each one was commanded by a Colonel.  Commands A and B were the primary combat force of the Division and R was the reserve. The Battalions could be swapped around between A, B, and R(sometimes called C) depending on strength and fatigue levels.

The Light Armored Division would also have a large number of service battalions and smaller units attached to make the Division as self-sustaining as possible:

One Armored Engineer Battalion

One Armored Medical Battalion

One Armored Reconnaissance Battalion

One Armored Ordnance battalion

One Armored Signal Company

A CIC Detachment

A Division Supply Train (made up of trucks)

A Division Artillery Battalion

A MP Platoon

A Tank Destroyer Battalion Could be assigned

An Armored AA Battalion Could be assigned

 

These units could be broken down into smaller, usually company sized sub units and assigned to the Combat Commands depending on the needs of the missions. The Armored Division was intended to be a self-contained unit with all the assets needed to support and move itself around a theater.  A light Armored Division had an authorized strength of just about 11,000 men, the Heavy Division had 14,500.

The main difference with a Heavy Armored Division was they had eight Medium Tank Battalions, instead of just three. They also had more light tanks, with two full light tank battalions, instead of three companies.  Only a two Armored Divisions retained the heavy designation and organization through the whole war, the 2nd and 3rd.  I have not been able to find a TO&E for a Heavy Armored Division that included an Authorized strength, but it would have to be several thousand men more than a normal AD.  I’m not 100% sure on this, but I’m pretty sure the Heavy Armored Division was done away with in a 1942 revision of what an Armored Division was, but a pair retained the Heavy TO&E for reasons I’m not sure of yet, but I will find out.

. . .

The Armored Divisions were meant to exploit a major breakthrough won by the regular Infantry Divisions.  In many cases they were not used this way, and often got thrown into the lines as the enemy was faltering, using a single Combat Command to help secure the breakthrough while the rest of the Division rushed through the breach.  No Armored Divisions saw use in the Pacific, but the Sherman sure did.  The Sherman was really the heart of the US Armored Division, and its mobility and reliability really served it well there, it allowed US Armored Divisions to make very long runs once broken through, and it would limits on fuel supplies, not the tanks mechanical reliability that slowed it down.

The oldest US Armor Division. It saw a lot of action in WWII, born on July 15 1940 at Fort Knox.

The 1st AD spent its early years figuring out what an Armored Division was going to be, and when they figured that out, they trained in the US until mid-summer of 1942 before shipped off to Northern Ireland, after a short stay they were off to England.  They were not there long, before they were shipped off to northern Africa for participation in Operation Torch.  The 1st AD would be the first US Armored Division to see combat.

They would participate in the capture or Oran, and the infamous Kassirine Pass, and then would fight to the end of the war in Italy.  The primary tank early on would have been the M3 Lee and M3 light.
