The M1A1 Thompson submachine gun, including the M1928A1, was widely used by the US military during World War II. The M1928A1 featured provisions for both box and drum magazines, a Cutts muzzle brake, cooling fins on the barrel, and a delayed blowback action with a charging handle located on top of the receiver.

The M1 and M1A1 variants, however, only had provisions for box magazines and lacked cooling fins on the barrel. They also featured a simplified rear sight and a straight blowback action with a charging handle located on the side of the receiver. These simplified versions were produced by Savage Arms and Auto-Ordnance after the M1928A1.

Over 1.5 million military Thompson submachine guns were produced during World War II, and the M1s were issued with a 30-round box magazine but could accept a 20-round box magazine. The Thompson was used by Allied troops for scouts, non-commissioned officers, patrol leaders, commissioned officers, tank crewmen, and soldiers performing raids on German positions.

The Thompson was widely utilized in British and Canadian commando units, as well as in the US Army paratrooper and Ranger battalions, where it was issued more frequently than in line infantry units. The gun was prized by those who used it and was effective in close combat situations, such as street fighting during the invasion of France.
