M4A3E2 Assault Tank – postwar nickname "Jumbo" – extra armor (including 1 inch on front, making it able to withstand shells from the German 88 millimeter guns), vertical sided turret, but about 3-4 mph slower at 22 mph. Built by Grand Blanc May-June 1944 with the T23 turret.
The M4A3E2 Sherman "Jumbo" assault tank variant, based upon a standard M4A3(75)W hull, had an additional 38 mm (1.5 in) plate welded to the glacis, giving a total thickness of 102 mm (4.0 in), which resulted in a glacis of 149 mm (5.9 in) line-of-sight thickness, and over 180 mm (7.1 in) effective thickness.

A 1954 survey concluded that there were in all 119, mostly small scale, tank vs. tank actions involving U.S. Army and Marine units during the Korean War, with 97 T-34-85 tanks knocked out and another 18 probables. The M4A3E8 was involved in 50% of the tank actions, the M26 in 32%, and the M46 in 10%. [65]
With the tank's very wide tracks, a design feature borrowed from the Soviet T-34, the Tiger had a lower ground pressure than many smaller tanks, such as the M4 Sherman. The first production series Tiger Fgst Nr 250001 with Motor Nr 46052 was only run-in for 25 km (16 mi) by Henschel before being sent to Kummersdorf for testing.
By August 1943, the M4 tank armed with the 76 mm gun in the modified T23 turret was finally ready for production. A proposal was made by the Armored Force for a test run of 1,000 tanks for combat trials and, if that was successful, then devoting all M4 tank manufacturing capacity to those armed with the 76 mm gun.

The T32 heavy tank was a heavy tank project started by the United States Army to create an appropriate successor to the M4A3E2 Sherman "Jumbo".The US Ordnance board managed the production of four prototypes, the main goal being to have the new tank share many common parts with the M26 Pershing.
Like all German tanks, the Tiger II had a petrol engine; in this case the same 700 PS (690 hp, 515 kW) V-12 Maybach HL 230 P30 which powered the much lighter Panther and Tiger I tanks. The Tiger II was under-powered, like many other heavy tanks of World War II [citation needed], and consumed a lot of fuel, which was in short supply for the ...
One main problem for the Sherman design, in its various forms, was the heavier guns on the German tanks coming onto the battlefield in the latter half of the war, especially the Tiger and Panther tanks. The German Tiger I tank was armed with a powerful 88 mm gun (originally developed from the 88mm Flak Gun) that made it a very dangerous ...
