The bazooka was an American, anti-tank, 2.36-in (60mm) rocket launcher. It was first used in combat in November 1942, in North Africa, during Operation Torch, in World War II. In service until 1957, it was also employed in the Korean War. The bazooka was an infantry weapon designed to knock out armored vehicles but was also effectively used against pillboxes and machine gun nests, being able to tear out gaping holes in thick brick walls. This man-portable, lethal weapon consisted of a 1.4-m-long steel tube, fitted with a wooden shoulder rest, two hand grips and a trigger group. Served by a two-man team, it electrically fired rocket-propelled, shaped-charge grenades to a maximum distance of 594 m, being able to pierce up to 119mm-thick armor. The shaped-charge grenade was loaded from the rear and was connected to the battery-powered trigger by a wire. Three bazooka models were produced; the M1, M1A1, and the M9, with the last one being able to be broken down in two pieces. Launcher weight: 6.01 kg (13.25 lb); shell weight: 1.54 kg. Muzzle velocity: 82.3 m/s.
