Originally devised by Colonel John Taliaferro Thompson as the perfect weapon for trench raiders in World War I, the Thompson Submachine Gun failed to attract the interest of the US Army until the mid 1930s. Though the early Model of 1921 had received favorable results in testing by the US Army and Marine Corps, these tests failed to result in the substantial orders that Thompson, and Auto Ordnance Corporation had been hoping for. The United States Navy was the first branch of the American military to purchase the weapon, but requested that the rate of fire be reduced from approximately 800 rounds per minute to 600, along with Cutts compensators and a horizontal handguard. This resulted in the Model of 1928. Little further interest materialized until the United States Cavalry began searching for an appropriate weapon to equip armored vehicle crews. In March of 1932, the US Army adopted the weapon as "non-essential limited procurement," a situation that did not change until September of 1938, with the situation in Europe rapidly deteriorating. Finally, the weapon was adopted as "Standard" and given the designation Submachine Gun, Caliber .45, Model of 1928A1.

Thompson submachine guns of this pattern were provided to the United Kingdom and USSR via the "Lend-Lease" program, and saw service with the United States Marine Corps in particular during the brutal fighting in the Pacific. Though officially withdrawn from service in 1945, Thompson submachine guns would continue to appear in conflict zones throughout the world, including the ongoing War in Ukraine.
