The Thompson is a .45 caliber American submachine gun, invented by John Talifero Thompson in 1919. It was initially marketed to the law enforcement officers as "Thompson's anti-bandit gun", but eventually became widely associated with the mafia. The weapon earned various nicknames such as the "Tommy Gun," the "Trench Broom," the "Trench Sweeper," the "Chicago Piano," the "Chicago Typewriter," and the "Chopper." The Thompson was adopted by the US Army during the World War II, and remained in service until the Vietnam War.
