The 5cm Panzerabwerkanone was a German anti-tank gun developed in 1938 by Rheinmetall-Borsig AG to succeed the 37mm PAK 36. The weapon first saw use in April 1941 during Operation Barbarossa. The Luftwaffe also used it as an anti-aircraft gun.
The PAK 38 was highly effective against Soviet tanks, capable of penetrating an 86mm armour plate sloped at 30 degrees at a range of 500 metres. If shot from 1,000 metres, it could penetrate 55mm armour. A high explosive round was also produced for the PAK 38, effective at 2,898 meters.
The gun remained in service with the Wehrmacht until the end of WWII. In addition, Bulgaria used it until early in the Cold War.
