The Sd.Kfz. 251 (Sonderkraftfahrzeug 251) half-track was a WW2 German armored fighting vehicle designed by the Hanomag company, based on its earlier, unarmored Sd.Kfz. 11 vehicle.
The Sd.Kfz. 251 was designed to transport the panzergrenadiers (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 various manufacturers, and were commonly referred to simply as "Hanomags" by both German and Allied soldiers.
