The Am General M915 was a series of military-spec semi-trucks that were first introduced for 1978. The M915, and its successors, the M915A1 and M915A2 were used by the US military, as well as other nations in order to haul cargo around the world. Production of the M915 and M915A1 was done by AM General until 1989, but after, Freightliner took over production with the M915A2.
