The Sd.Kfz. 251 half-track was a World War II German armored personnel carrier designed by the Hanomag company, based on its earlier, unarmored Sd.Kfz. 11 vehicle. The Sd.Kfz. 251 was designed to transport the Panzergrenadier into battle. Sd.Kfz. 251s were the most widely produced German half-tracks of the war, with at least 15,252 vehicles and variants produced by seven manufacturers. The utility of this vehicle led the German Army to develop the similar looking but shorter and lighter Sd.Kfz. 250 as a supplement.

A half-track is a civilian or military vehicle with regular wheels at the front for steering and continuous tracks at the back to propel the vehicle and carry most of the load. The purpose of this combination is to produce a vehicle with the cross-country capabilities of a tank and the handling of a wheeled vehicle.
