Much of the NSKK was used to support the Luftwaffe. The Luftwaffe often used big tanker trucks to haul fuel around. The Army did not use tanker trucks much, they used barrels and fuel cans.
This big Mercedes Benz fuel truck with two troops, one from Italeri and the other from HaT.
The Italeri motorcycle with tanker truck. This type of truck would be used to service an airfield. The truck goes to the nearest railhead and fills from a railway tanker car. Then it returns to the airstrip and refuels the airplanes.
