M3 Lee

The M3 Lee, officially Medium Tank, M3, was an American medium tank used during World War II. The turret was produced in two different forms, one for US needs and one modified to British requirements to place the radio next to the commander. In British Commonwealth service, the tank was called by two names: tanks employing US-pattern turrets were called "Lee", named after Confederate general Robert E. Lee, while those with British-pattern turrets were known as "Grant", named after Union general Ulysses S. Grant. Design commenced in July 1940, and the first M3s were operational in late 1941. The US Army needed a medium tank armed with a 75 mm gun and coupled with the United Kingdom's immediate demand for 3,650 medium tanks, the Lee began production by late 1940. The design was a compromise meant to produce a tank as soon as possible and serve only until replaced by the following M4 Sherman tank. The M3 was reliable, had considerable firepower, good armor, and high mobility but had serious drawbacks in its general design and shape, including a high silhouette, an archaic sponson mounting of the main gun preventing the tank from taking a hull-down position, and riveted construction. It was considered by Hans von Luck (a German army officer who wrote the post-war memoir Panzer Commander), to be superior in May 1942 to the Panzer IV and able to operate out of range of German 5 cm anti-tank guns. However, by mid-1943, with the introduction of upgunned Panzer IIIs and Panzer IVs, the tank had been withdrawn from combat in most theaters and replaced by the more capable M4 Sherman tank as soon as it became available in larger numbers. Despite its being replaced elsewhere, the British continued to use M3s in combat against the Japanese in southeast...
