The Panzer IV was developed during the opening months of World War Two to equip German armoured divisions with a tank having a 7.5 cm cannon.

Given the shortcomings of the previous Panzer III, equipped with a 5 cm gun (often in difficulty against the Soviet T34 with its 5 cm gun and highly effective armour), it also featured enhanced protection.

The Mark IV was used extensively by the German Army on all fronts during the Second World War: numerous variants were produced to counter the constant improvements made to enemy tanks.
