Bazooka

Bazooka is the common nickname for a man-portable rocket launcher widely fielded by the US Army during World War II. Also referred to as the "Stovepipe", the innovative Bazooka was amongst the first-generation of rocket propelled anti-tank weapons used in infantry combat. Featuring a solid rocket motor for propulsion, it allowed for high explosive (HE) and high-explosive anti-tank (HEAT) warheads to be delivered against armored vehicles, machine gun nests, and fortified bunkers at ranges beyond that of a standard thrown grenade or mine. The universally-applied nickname arose from the M9 variant's vague resemblance to the tubular musical instrument of the same name invented and popularized in the 1930s by US comedian Bob Burns.

German Iteration
During the war, German armed forces captured several in early North African encounters and, recognizing the inherent advantages of the design, soon reverse engineered their own version, increasing the warhead diameter to 8.8 cm (amongst other minor changes) and widely issuing it as the Raketenpanzerbüchse "Panzerschreck" ("Tank terror").

Today
Due to the novelty and easy recognition of the name, the term "bazooka" continues to be used informally as a genericized term to refer to any shoulder-launched missile weapon.
