Initially, the chassis of captured light tanks were used after turrets were removed, providing a cost-effective solution to the German shortage of mobile anti-tank weapons in infantry divisions. Despite the shortcomings of light armour and high silhouette, they were successfully used in their intended role, which was basically a self-propelled anti-tank gun. Neither anti-tank guns nor Panzerjägers had any real armor to speak of, and while the Panzerjäger had a higher silhouette and was more visible than an anti-tank gun, it was also much more mobile, and was able to relocate or retreat far more rapidly than conventional anti-tank gun crews.
