88 is there to be used as on-map direct-fire support weapon, mainly Anti-Tank. It is not there to shoot at enemy aircraft. The reason it is called FlaK 18 or FlaK 36 is to differentiate it from the pure same-caliber tank killers, like 88mm PaK 44. However the purpose of these guns in-game is exactly the same, mainly to blast matildas, t-34s, Kvs, etc.
