The M4 Sherman retained much of the mechanical design of the M3, but it addressed several shortcomings and incorporated improvements in mobility, firepower, and ergonomics. One of the most significant changes was the relocation of the main armament—initially a 75 mm gun—into a fully traversing turret located at the center of the vehicle.
Originally designed in 1941, M4 variants were still used by Israel during the 1967 and 1973 wars with its Arab neighbors.

The primary legacy of the T23 would thus be its production cast turret, which was designed from the outset to be interchangeable with the turret ring of the M4 Sherman. The T23 turret was used on all production versions of the 76 mm M4 Sherman as the original M4 75 mm turret was found to be too small to easily mount the 76 mm M1A1 gun.
DD or duplex drive tanks, nicknamed "Donald Duck tanks", [1] were a type of amphibious swimming tank developed by the British during the Second World War.The phrase is mostly used for the Duplex Drive variant of the M4 Sherman medium tank, that was used by the Western Allies during and after the Normandy Landings in June 1944.
The M4 high-speed tractor used M4 Sherman tracks, roadwheels, and drive sprocket. However, the suspension was of the HVSS type, first introduced on a light tank T6 project in 1938. One variant was designed to tow the 90 mm anti-aircraft gun , and another was for the 155 mm gun or 8-inch howitzer . [ 1 ]
Battle experience showed that the service life of the original vertical volute spring suspension (VVSS) of the late model M4 was shortening due to the tank's increasing combat weight with larger guns and heavier armor. Beginning in mid-1944, M4A3 models of the Sherman adopted a newly developed Horizontal Volute Spring Suspension (HVSS). [5]
