The original Panzer 1 A was a small 2 man light tank armed with twin machine guns, primarily for crew training. Two combat versions were developed as the Panzer 1 C and Panzer 1 F. The Panzer 1 C was a light tank with 20mm cannon for use in the reconnaissance role. While the Panzer 1 F was designed as an infantry support tank with twin machine guns and heavy armour. Both features new suspension and more powerful engines.
A total of 40 (+6 prototypes) Panzer I Ausf C's were produced. Two of them were sent to the 1st Panzer Division while the rest were deployed to the Panzer reserves in Northern France and saw action in Normandy
