The PaK 40 remained relevant until the end of the war, being able to pierce the armour of almost any Allied tank. Its standard ammunition was the Panzergranate 39 (PzGr. 39) Armoured Piercing, Capped, Ballistic Cap (APCBC) which fired at a velocity of 790 m/s, and was capable of penetrating the armour of the Soviet KV-1 tank at 500 meters. It also had the Panzergranate 40 (PzGr. 40) Armor Piercing, Composite Rigid (APCR) shell which had a tungsten core with a muzzle velocity of 990 m/s but these became more scarce as the sources of tungsten dried up. The gun would be crewed by 5 men, but if the situation required, the entire gun could be operated by just a single soldier. The rate of fire by a trained crew was 14 rounds per minute but on average the rate of fire was a respectable 11 rpm. Each gun would form one part of a platoon (3 guns) which in turn would form one part of a battery (3 platoons). These would be motorized, towed by Sd.Kfz.7, 8 or 11’s, and supported by a signals and HQ platoons
