the Panzer IV series was primarily designed to act as a fire support vehicle for other slightly weaker armed Panzers. For this role, they were armed with the 7.5 cm K.w.K. L/24 short-barrel gun. Their targets were usually fortified enemy positions or machine gun nests. These were usually marked by other tanks using smoke grenades. Once the target was identified, the 7.5 cm high-explosive rounds were more than enough to successfully neutralize these threats. However, it is often forgotten.
