The [b]Panzerkampfwagen IV[/b] (Pz.Kpfw. IV), commonly known as the [b]Panzer IV[/b], was a medium [[tank]] developed in [[Nazi]] Germany in the late 1930s and used extensively during [[World War II]]. Its ordnance inventory designation was Sd.Kfz. 161.

Designed as an infantry-support tank, the Panzer IV was not originally intended to engage enemy armor—that function was performed by the lighter [[Panzer III]]. However, with the flaws of pre-war doctrine becoming apparent and in the face of [[Soviet]] [[T-34]] tanks, the Panzer IV soon assumed the tank-fighting role of its increasingly obsolete cousin. The most widely manufactured and deployed German tank of the Second World War, the Panzer IV was used as the base for many other fighting vehicles, including the [[Sturmgeschutz IV]] assault gun, [[Jagdpanzer IV]] tank destroyer, the Wirbelwind self-propelled anti-aircraft weapon, and the Brummbär self-propelled gun.
