The WM3 is an American .45-caliber submachine gun adopted for U.S. Army service on 12 December 1942. It was chambered for the same .45 ACP round fired by the Thompson submachine gun, but was cheaper to produce and lighter. The M3 was commonly referred to as the "Grease Gun" or simply "the Greaser," owing to its visual similarity to the mechanic's tool.
