High-Mobility Truck, D, 3-1/2 t (Steyr 680 M3F)
At the end of the 1970ies it became more and more apparent that the Steyr Type 680 trucks that had been in service since the mid-1960ies had to be replaced. These started in 1985 and resulted in the Steyr 12M18 being introduced in 1986. In 1979 however, six vehicles were assembled in a configuration that was never part of any official type catalogue: 6x6 chassis with double-cab and second steering wheel for driver training purposes.
