*NOTE: in the video I state that the 10th Mountain Division served in Burma. It seems I got my notes mixed up; the 10th served mainly in Italy. The M1A1 was used by other units in Burma, including the Chindits and Merrill's Marauders.

Introduced in 1927, the M1A1 Pack Howitzer was designed for use in mountainous terrain, and could be disassembled into 7 smaller load for transport by mule or horse. During the Second World War, it was widely used as airborne artillery, able to be transported by transport aircraft, dropped by parachute, or landed by assault glider.
