The mittlere Schützenpanzerwagen (7,5 cm) (Sd. Kfz. 251/9) was developed as supporting vehicle of the motorised infantry. Two prototypes were tested on the east front beginning in June 1942. In July 1942, an order for 150 vehicles was placed. Serial production started in October or November 1942.

The Sd. Kfz. 251/9 was armed with a 7.5cm KwK L/24. This weapon was available in larger quantities after the Panzerkampfwagen IV and Sturmgeschütz III were rearmed with more effective weapons.
