Flakpanzer is a German term for "anti-aircraft tanks" ("flak" is derived from Flugabwehrkanone, literally "aircraft defence cannon"; "panzer" is derived from Panzerkampfwagen, literally "armored fighting vehicle"). These vehicles are modified tanks whose armament was intended to engage aircraft, rather than targets on the ground.
Several vehicles with this name were used by the German Army during World War II. After the war, others were used by both the West German Bundeswehr and the East German National People's Army.
