@Frank:
If I do a bombing raid on a city that has an AA gun and I bring fighter escorts. Does the AA gun fire on my escorts or just my bombers?
I believe just the bombers. Pretty sure AA firing occurs after the fighter escort/intercept casualty rolls and only targets the bombers that got through the fighter screen.
if i conduct a SBR on a Naval Port In Gibraltar with 2 german bombers… the 3 fighters on Gibraltar can scramble or only fire the AA gun?
Scrambling is different than strategic bombing escort/interception.
Yes, all three fighters can INTERCEPT the bombers and each plane gets a roll. Any territory that is a valid strategic bombing target (has a factory, airbase or naval base) can use fighters to INTERCEPT bombers on a run against one of those targets, but these fighters cannot participate in any other battles during that round.
