M-19 MGMC 40mm twin gun

M.19 air defense vehicle consisted in the assembly of two 40mm Bofors AA guns on a M.24 Chaffee light tank chassis. It was put into service in 1944 and sent to Europe for the last stakes of WWII, where it served more as an assault gun than an AA vehicle. The M.19 participated in the Korean War, where it was lethal against the Chinese infantry mass attacks. Cadillac and Massey-Ferguson of Canada produced more than 900 units that were in service until the 60s, when it was replaced by the M.42 Duster, which consisted in the assembly of the retired turrets from the M.19 on a new M.41 light tank chassis. In addition to the United States, only Japan operated a few vehicles of this type, when they received a small quantity from the U.S. Army for the new created Japanese Army in 1954.
