	The M3, an American .45-caliber submachine gun, was adopted by the U.S. Army on December 12, 1942, as a cheaper and lighter alternative to the [[M1A1 Thompson]] submachine gun, although it sacrificed some accuracy. Nicknamed the "Grease Gun" for its resemblance to a mechanic's tool, it began frontline service in mid-1944 and saw use in the Korean War as the M3A1 variant. Intended to be replaced by the [[M14]] rifle in 1959, which proved unsuitable due to its powerful recoil in full auto, the M3A1 was ultimately succeeded by the [[M16]] in 1964. Despite being retired from frontline service after 1959, the M3A1 continued to be issued as backup weapons, notably for armored vehicle crews, until the mid to late 1990s.

	In 1941, the U.S. Army Ordnance Board, impressed by the German [[MP 40]] and British [[Sten]] submachine guns, initiated a study to develop a similar weapon in October 1942. The requirements called for a .45 ACP all-metal weapon with full and semi-automatic fire capabilities, fast production, and a low cyclic rate of fire. George Hyde of General Motors' Inland Division designed the weapon, resulting in the T20 prototype, which passed initial trials with high accuracy and reliability despite some magazine issues.
