The Sd.Kfz. 251 (Sonderkraftfahrzeug 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 (German mechanized infantry) 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.
Sd.Kfz. 251/9 - Schutzenpanzerwagen (7.5 cm KwK37). Equipped with a 75 mm L/24 low velocity gun, using the same pedestal gun mount employed on the StuG III. Nicknamed "Stummel" ("stump"). In 1944, a revised modular gun mount was introduced to facilitate production that also incorporated a coaxial MG42.
