The M-2 Halftrack is similar to the slightly larger and more common M-3 Halftrack, produced at the same time during WW II. To distinguish the M2 from the M3 halftrack, the longer M3 body extends further beyond the tracks while the M2 body stops close to the end of the tracks and has a step at the rear. The M2 had no rear access door, which would be blocked by its machine-gun skate rail. The driver area of the M2 halftrack is separated from the rear compartment by storage bins, accessed by doors on the sides of the vehicle. Note: halftrack is sometimes spelled "halftrac".
The M2A1 halftrack, fielded in 1943, had a ring mount machine gun that replaced the machine-gun skate rail. During the production life of the M2 many small changes were made, in parallel with the M3, including spring-loaded idlers, demountable headlights moved from the fenders to the side of the hood, mine racks, and a winch.
The M-4 Mortar Carrier Halftrack is based on the M2 Halftrack.
