Panzer III

The Panzerkampfwagen III (Pz.Kpfw. III), commonly known as the Panzer III, was a medium tank developed in the 1930s by Germany, and was used extensively in World War II. The official German ordnance designation was Sd.Kfz. 141. It was intended to fight other armoured fighting vehicles and serve alongside and support the similar Panzer IV, which was originally designed for infantry support.

Initially, the Panzer III had the same 3.7 cm gun as the infantry used in an anti-tank role, but later models were given the 5 cm KwK 38 gun. This was the largest gun that could be fitted within the physical limitations of the turret ring, but it turned out to be ineffective against Soviet T-34 and KV-1 tanks. The Panzer IV, which had a larger turret ring, was redesigned to mount the long-barrelled 7.5 cm KwK 40 gun and became the main German tank instead. Produced from 1942 onwards, the last version of the Panzer III (Panzer III N) mounted the short barrelled 7.5 cm KwK 37 L/24 which was used on the first Panzer IVs, meaning the Panzer III and the Panzer IV had effectively swapped roles.
