The role of the German anti-tank guns increased in importance as the war wore on and the new battlefield realities the Wehrmacht ground troops had to face. The German foot soldiers entered World War II equipped with only one type of anti-tank gun; the 3.7 cm Pak 36, which could defeat only lightly armored enemy tanks in the Polish Campaign, the Battle of France, and the Balkan Campaign from September 1939 to April 1941. However, in late 1941, four months after the beginning of Operation Barbarossa, the battlefield reality changed for the German infantry with the emergence of the Soviet T-34, a fast and mechanically reliable tank with good armor protection, and, by 1943, a new Russian heavy tank would also crop up on the Eastern Front horizon: the IS.

These tanks were immune to this German underpower anti-tank gun, with which the Wehrmacht had gone to war. These raw facts of war forced the Germans to develop much more powerful and effective anti-tank weapons. Meanwhile, they had to resort to AA guns, like the 88mm, which became effective tank killers.
