The M4A3E2 assault tank, affectionately called the Jumbo, was a heavy/assault tank based of the M4 Sherman’s hull and VVSS suspension system and late war turret, changes essentially boil down to a new upper hull and in terms of relative armour thickness a substantially thicker UFP and transmission cover along with a new mantlet for the turret. Some jumbos were modified in the field to have the 76mm gun. Overall relatively few jumbos were actually produced due to crews and regiments not needing anymore than they already had.

Controls

This is the last Saunders tank I swear (unless I make a Sherman VC then that will be the last one)
