Kettenkrad: History, Production, Production Batches, Combat

The SdKfz 2, better known as the Kleines Kettenkraftrad HK 101 or Kettenkrad for short (where Ketten means "chain" or "tracks" and krad is the military abbreviation of the German word Kraftrad, the administrative German term for motorcycle), started its life as a light tractor for airborne troops. The vehicle was designed to be delivered by Junkers Ju 52 aircraft, though not by parachute. The vehicle had the advantage of being the only gun tractor small enough to fit inside the hold of the Ju 52, and was the lightest mass-produced German military vehicle to use the complex Schachtellaufwerk overlapped and interleaved road wheels used on almost all German military half-track vehicles of World War II.
