KetenKrad Walk Around
By ERIK ROBERSON

The SdKfz 2, better known as the Kleines Kettenkraftrad HK 101 or Kettenkrad, tarted 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. -
