Background
The 2.8 cm schwere Panzerbüchse 41 (sPzB 41) or "Panzerbüchse 41" was a German anti-tank weapon working on the squeeze bore principle. Officially classified as a heavy anti-tank rifle (German: schwere Panzerbüchse), it would be better described, and is widely referred to, as a light anti-tank gun as its construction was much more typical of an anti-tank gun. It was produced between 1940 and 1943 with a total of 2,797 seeing service.
