M4 Sherman Tank 3D model

The M4 Sherman, officially Medium Tank, M4, was the most widely used medium tank by the United States and Western Allies in World War II. The M4 Sherman proved to be reliable, relatively cheap to produce, and available in great numbers. Thousands were distributed through the Lend-Lease program to the British Commonwealth and Soviet Union. The tank was named by the British for the American Civil War general William Tecumseh Sherman.

The M4 Sherman evolved from the M3 Medium Tank,[N 1] which had its main armament in a side sponson mount. The M4 retained much of the previous mechanical design, but moved the main 75 mm gun into a fully traversing central turret. One feature, a one-axis gyrostabilizer, was not precise enough to allow firing when moving but did help keep the reticle on target, so that when the tank did stop to fire, the gun would be aimed in roughly the right direction.[6] The designers stressed mechanical reliability, ease of production and maintenance, durability, standardization of parts and ammunition in a limited number of variants, and moderate size and weight. These factors, combined with the Sherman's then-superior armor and armament, outclassed German light and medium tanks fielded in 1939–42. The M4 went on to be produced in large numbers, being the most produced tank in American history:[7] The Soviets' T-34 medium tank (total of some 64,549 wartime-produced examples, split roughly 55%-45% between 76 mm and 85 mm gunned examples) was the only tank design produced in larger numbers[8] during World War II. The Sherman spearheaded many offensives by the Western Allies after 1942.
