M10 Tank Destroyer

[Robert]

The M10 tank destroyer was a United States tank destroyer of World War II based on the chassis of the M4 Sherman tank fitted with the 3-inch (76.2 mm) Gun M7. Formally 3-inch Gun Motor Carriage, M10, it was numerically the most important U.S. tank destroyer of World War II and combined a nearly all-sloped armor adaptation of the Sherman hull and drivetrain, with a reasonably potent anti-tank weapon emplaced within an open-topped, 360º rotation turret mount for its main armament, establishing the American style of World War II "tank destroyer"-designation, fully tracked ordnance platform. This was quite unlike the previous M3 GMC, whose gun was capable of only limited traverse, as essentially an adaptation of a self-propelled artillery platform. Despite the introduction of more-powerful types as replacements, it remained in service until the end of the war, and its chassis was later reused with a new turret to create the M36 Jackson, which used a 90mm gun instead of the 76.2mm gun.
