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.
