Kleines Kettenkraftrad (small tracked motorcycle)
The Kleines Kettenkraftrad HK 101 often called the Kettenkrad was tracked motorcycle developed by the Germans during World War II. It was small enough to be transported in the JU52, the work horse airplane and the German Fallschirmjagers or paratroopers.
Given the nomenclature SdKfz2, the vehcile was intially to be used with the paratroopers as a light tractor. After the high casualty rates suffered by the paratroopers in the Crete invasion the paratroopers became elite light infantry and no longer were used in airborne operations and the need of an airborne tractor vanished.
However the Kettenkrad proved to be reliable and rugged and wnet on to serve no only with German airborne forces but with the Army and SS units as well.
While most of the vehicles saw service on the Eastern Front they were also widely employed in North Africa and to soem extenet on the Western Front.
