Wings and Wheels Publications
The M939 5-ton truck is the direct successor of teh previous M809 series and the original M54. Vehicles of the M54 family were the main workhorse during the Vietnam War, where the idea arose of rebuilding trucks into heavily armed vehicles known as Guntrucks to protect convoys. The designation M939 refers only to the bare chassis with cab, with individual-numbers for the complete vehicles. The M939 series was put in service in 1989 beside teh M809 series vehicles whose service was ending, and was teh main allied truck in the first Gulf War in the 1990s.
