The American Bazooka was first used in North Africa and on Tarawa in November 1942. The first version (M1A1) had two grips and a wooden support. By 1943 the new version was released which no longer had the front grip but had an improved electrical firing system. The final version was longer (1.55m) and improved the range from 200-250 yards to 300 yards. The M6 HEAT rocket could easily penetrate 76mm of armour at 30° or 110mm at 90°.
