Comparing: M4A3E2 Sherman Jumbo vs. AC 4 Experimental

This variant of the Sherman featured much heavier armor. The M4A3E2 was initially intended as an infantry support tank. However, some were re-equipped with the M1A1 gun and served as tank hunters.

The tank was developed in 1943. An order was placed for 400 vehicles. The prototype was created on the basis of the AC 1 tank with an enlarged superstructure, which allowed mounting a modified turret from the AC 3 tank with a 17-pounder gun. In July 1943, the work on the project was stopped at the final stage, as the program for creating the Australian cruiser tank was discontinued.
