After a decade of testing and research, in 1960 the U.S. Army began fielding the 1/4-ton utility truck with independent suspension that it thought it wanted – the Ford M151 Military Utility Tactical Truck (MUTT). By 1964, the vehicle had been redesigned with a heavy duty rear suspension, and re-designated the M151A1. This vehicle would see wide use in Vietnam – and everywhere else in the world U.S. troops were found.
In 1969, a new generation of the vehicle rolled off the assembly line. The M151A2 featured a semi-trailing arm rear suspension rather than the independent A-frame suspension. Production of the M151-series vehicles for the U.S. military ended in 1982 after having been produced by Ford, Kaiser-Jeep and lastly AM General.
