The Thompson is an American submachine gun, invented by John T. Thompson in 1919, too later for service in World War I as it was originally intended. As there were no restrictions on sale of automatic weapons at the time, Thompson put the weapon on the civilian market, where became infamous during the Prohibition era. It was a common sight in the media of the time, being used by both law enforcement officers and criminals. Indeed, the widespread use of the Thompson in crimes was one of the reasons for the first firearms laws, the National Firearms Act. The weapon later went on to be used in hands of U.S. and allied troops in the Second World War. The Thompson was also known informally as: the "Tommy Gun", "Trench Broom", "Trench Sweeper", "Chicago Typewriter", "Chicago Piano", "Chicago Style", "Chicago Organ Grinder", and "The Chopper".
