The “Tommy gun” as it was popularly called, is an automatic weapon developed for American forces during World War I. Between the first and second world wars, technology developed and changed this firearm. Yet, the Tommy gun maintained an important role in arming the Allies for the Second World War. Between the First and Second World Wars this automatic weapon was modified. Allied forces used the Thompson Machine Gun extensively in both the Pacific and European theaters of war in close combat situations throughout World War II.
