The German 88mm anti-tank artillery gun earned one of the biggest fames during World War II, not only because it was a powerful piece of weapon that could be used against ships, ground vehicles and airplanes, more importantly because it was exactly the same gun design being deployed to the mighty German Tiger tanks series. In post war interviews with Allied troops, they claimed that the FLAK gun was an unfair weapon being deployed in ground battle. In German, the 88mm anti-tank artillery gun was commonly called ?The FLAK gun?, the word FLAK is abbreviation of German word ?Fliegerabwehrkanone? in English, meaning ?aircraft-defence gun?.
