Towards the end of the 1950s, several versions of the Saurer 6 truck were introduced to army service. The open cab version saw service with the air defense troops, mainly for towing the 4cm Bofors AA gun. In addition to the ten-man gun crew, the truck also carried ammunition and replacement barrels.
The vehicle was equipped with an inline 8-liter 6-cylinder four-stroke Diesel engine, producing 140 HP. Due to this not overwhelming engine power, these trucks were phased out by 1967 and replaced by the Berliet GBC 8MT.
