Since then, the weapon system went on to make its mark in the Prohibition era (fighting for both gangsters and police forces alike), found tremendous combat successes in World War 2 and saw use in the Arab-Israeli War of 1948, the Korean War, the 1st Indochina War, the Vietnam War, the Chinese Civil War and the Bosnian War to name a few conflicts. It was the creation of one General John Taliaferro Thompson (December 31st, 1860 - June 21st, 1940) who started work on early forms as early as 1917. The Thompson series of submachine guns (not quite a pistol yet not a full-fledged machine gun) began life in 1919 following World War 1.
