The 155 mm Howitzer Motor Carriage M41 (also known as the M41 Gorilla) was an American self-propelled artillery vehicle built on a lengthened M24 Chaffee tank chassis that was introduced at the end of the Second World War. Out of a planned run of 250, only 85 were produced before cancellation of the order at the end of 1945.^[1] The M41 went on to serve extensively in the Korean War, its success influencing the design of later U.S. self-propelled artillery. The type was retired after the conclusion of that conflict but went on to serve in the French Army from 1956 to 1972.^[2]
