The Panzer IV Ausf. G evolved into the Ausf. H with the addition of a slightly improved L/46 75mm high velocity anti-tank gun. The Ausf. H would become the standard German battle tank until the final Ausf. J was developed, but this only had minor changes, such as the improvement of the gearbox and the turret's roof armour. If any tank can claim to be the standard battle tank of the German Army then it is the Panzer IV.
