NotesThe M37 was designed as a replacement for the M7. It was mounted on the chassis of the M24 light tank which gave it better mobility than its predecessor the M7 and mounted the improved M4 105mm howitzer. It had an open superstructure similar to the M7 and carried a .50 cal HMG in a raised gun turret. It was first issued in 1945 and came too late to see action in World War Two. Production numbers never equalled that of the M7 but it saw service in Korea War. It was finally replaced in front line service by the M52 HMC, but remained in use with the US National Guard.
