@Cobert:
It’s like when people try to incorporate the rules from Europe involving bomber escorts into Revised or AA50 - with each turn representing a period of several months and each territory representing miles upon miles of land or entire countries, I think it’s insane that they want a rule that makes a unit shaped like a fighter accompany a unit shaped like a bomber to actually mean that there are fighter escorts with the bomber.
Well I can see your point ref scale of the action and so I’d support the geographic boundary with no house rule for CAP or any FTRs defending adjacent space etc.
But otherwise, I’m leaning towards the optional escort / interceptor rule as it reflects the operational decision on whether you use your fighter resources defensively or base them forward to project air cover.
