NotesBased on the chassis of the M3 and built by Autocar. The M3 GMC was an early attempt at providing mobile units with direct fire, the gun itself was of French design and the vehicle was employed in the Tank Destroyer role along with the lighter M6 37mm GMC, the M3 GMC was gradually phased out due to the introduction of the more potent M10, the US Marines still found a use for them and they were kept in service until 1945 when they replaced them with M7s. The M3 GMC saw action in Philippines, North Africa and Sicily and with the Marine Corps in Saipan, Peleliu and Okinawa.
