1x7 - Guns: The Evolution of Firearms

Two decades after World War II, American forces entered into the Vietnam Conflict and required a new weapon to face a new enemy on a new battlefield. The heavy hitting (and flat-out heavy) M14 was developed and deployed but short-lived as a main battle rifle as its limitations were exposed in the conflict. It was replaced by the lightweight M16, a smaller-caliber .223 rifle described as a "Mattel toy" upon its initial deployment. It, too, was limited in battle, at first, lacking a chrome-lined barrel and chamber and cleaning instructions and equipment for operators. But with the introduction of the A1 model, the weapon began to prove its worth. Examined later in episode seven is the development of the A2 version and on through to today's M4 carbine. Also highlighted are the M60 machine gun, the M249 machine gun, the M79 "thumper" grenade launcher, and the M203 weapons-mounted grenade launcher. Of course, the piece also explores the origins and the proliferation of the AK-47.
