International Harvester Company M5 and M5A1 half-track

The M5 was created out of a need to produce more M3 half-tracks. White, Autocar, and Diamond T could not keep pace with the demand for half-track personnel carriers. The International Harvester Company (IHC) was requested to also make the half-track, but because differing manufacturing equipment some changes had to be made to the design. These became the M5 and M5A1 half-tracks.
