Panzer I
The first Panzer I vehicles to be built, 15 of this variant were completed by various firms (Daimler-Benz, Henschel, Krupp, MAN, and Rheinmetall) in a program intended to develop industrial capacity and provide initial training vehicles to the Wehrmacht. The Ausf A ohne Aufbau was a Panzer I hull without any superstructure or turret. The interior was completely open. The vehicle was crewed by a student driver and instructor, with room for three student observers behind them. The suspension and hull were identical to the Ausf A, but total weight was reduced to 3.5 tons and height to 1.15 m. Performance was similar.
