One feature, a one-axis gyrostabilizer, was not precise enough to allow firing when moving but did help keep the gun aimed in roughly the right direction for when the tank stopped to fire. The M4 retained much of the previous mechanical design, but moved the main 75 mm gun into a fully traversing central turret. The M4 Sherman evolved from the M3 Medium Tank, which – for speed of development – had its main armament in a side sponson mount. The tank was named by the British after the American Civil War General William Tecumseh Sherman. Tens of thousands were distributed through the Lend-Lease program to the British Commonwealth and Soviet Union. It was also the basis of several other armored fighting vehicles including self-propelled artillery, tank destroyers, and armored recovery vehicles. The M4 Sherman proved to be reliable, relatively cheap to produce, and available in great numbers. 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.
