The German anti-tank weapons used in WWII were divided into several classes. The main class, which we will deal with in the following volume, comprises guns built specifically for anti-tank missions and is in turn divided into three groups: guns of conventional German design, guns built with conical bore systems and anti-tank weapons captured from the enemy. The orthodox German cannon in the first group are designed to pierce enemy armour at maximum distances using relatively heavy projectiles at high velocity. The cone-core cannon group, on the other hand, were designed to have greater mobility than conventional cannon, while still being able to achieve the same armour penetration. Finally, the third group of anti-tank weapons comprises all those weapons that the German army used during its conquests in the early years of the war. The Germans used them mainly as reserve weapons!
