The fuel system for five ton trucks allows any five ton cargo truck to be used as a fuel carrier. In former times, only specialized tanker trucks could carry fuel, and enemy forces would target them particulaly. Destroy the enemies fuel and you immobilize all his vehicles. Each system included fuel tanks and a pumping station, so tanks, trucks, and other vehicles can drive right up to the back of the cargo truck and refuel.
