The Panzer IV (also known as the PzKpfW. IV) was a German medium tank used extensively for the blitzkrieg tactics of the early part of World War II. They were designed as infantry support vehicles, and as such carried a relatively light 7.5 cm KwK 40 and several MG34s. Their appearance is prominent in the WWII-era of the Medal of Honor franchise. It is impenetrable by normal weapons, although the MG42 can dispose of the Panzer IV quite easily. It is considered an antithesis to the M4 Sherman medium tanks, although its armament and weapon loadout are actually more advanced and powerful than that of the Shermans.
The Panzer IV debuts in Medal of Honor: Underground, as the most common German tank in the game. It appears in Mission 1, Mission 2, Mission 5, and Mission 6. It can only be destroyed by rockets and grenades.
In Medal of Honor: Frontline the Panzer IV is the most common German tank in the game. It is immune to small arms fire but can dealt gradual damage from grenades and rockets. It is worth noting that fire from an MG42 can dispose of Panzer IVs within a matter of seconds but can be used to the players advantage.
The Panzer IV is fought frequently in Medal of Honor: Allied Assault and its expansion packs. Unlike in the previous installments, the Panzer IV can only be damaged using rockets or satchel charges/sticky bombs.In Breakthrough on the first level it's also drivable.
In Medal of Honor: European Assault the Panzer IV is fought in Stalingrad.
In Medal of Honor: Vanguard it is fought in Operation Neptune. It would be replaced by the Tiger tank in later missions.
