The introduction also describes the next two models, NO-4 and NO-5, which were wreckers rather than prime movers. The NO-4 trucks were used by the Army Air Forces as aircraft wreckers, whereas the NO-5 was intended for field artillery use. The NO-6 trucks were intended for Allied use through the Lend-Lease program, and the NO-7 was the final model of the wartime prime movers.
