So say I bomb your enemy land unit and you intercept. That interceptor will use A2A. The target land unit will use its AA
But if I bomb the interceptors airfield it will fight A2A then use its AA before you bomb.
That is how it works. The Air counter is basically a setup airfield with defenses. The defenses only work if that air fiend is targeted
That would seem to make Air Superiority Interceptors rather weak at intercepting depending on how the game actually calculates the combat. For example, a 1942 level Interceptor has an AC rating of 9 but a AA rating of only 3. If a similar enemy interceptor does an interception would that mean the attacker would use a factor of 9 against the defending interceptor's 3?
And, if I am following your airfield explanation correctly, if the attacker's Interceptors instead targeted the actual hex the enemy interceptor was placed in (airfield marker), it would have to fight twice. Once against the unit's AA and again against its AC?
