White began the M2 in 1940 and Autocar was added to the programme; about 13,500 M2s and derivatives were built, two men and nine tonnes, drawn as an artillery tractor and used for reconnaissance and machine-gun squads too. The M2A1 put the improved M49 ring mount over the right front seat.
The M3 was the same idea made longer: a rear door, five more seats, a driver and twelve men, two M1919s and an M2 Browning, 17,650 lb and 18,425 in the M3A1. It was tested at Aberdeen in the summer of 1941 and accepted soon after; about 15,000 standard M3s were built and more than 53,000 vehicles on the design in all, by White, Autocar and Diamond T, with International Harvester's near-identical M5 for Lend-Lease.
