Nope. Facility aa only fires at the bombers directly attacking it. Unit aa guns only fire if their territory is being attacked.
Side note, it would be cool if aa could chose to defend air or ground combat. Like german 88s being used as anti tank guns and 20mm being used against infantry and lite vehicles. Oh well. Back to the game.
Right but AnA will never have a version where each unit has its own attack against certain units. I do think about AA guns should have the ability to shoot at infantry on defense. Each nation in WWII AA guns could be aimed at the ground and I am sure you can find evidence of everyone doing it at some point.
AnA will never try to have a unit that can do better or worse against different units. IE fighters rolling a 3 against other fighters but a 1 against a battleship and G40’s rules for fighters on strategic bombing doesn’t count.
Submarines (and Destroyer somehow vs Sub) and AAA got special targeting. And these units saw various changes.
I saw no outright evidence against more room about special targeting. Do you ?
