Air Superiority
When conducting combat, and only one side has fighters, the fighters may dive bomb on a role of 5 during the opening fire stage of combat. After wards, the fighters conduct combat normally.
this would be an excellent use for a 2nd fighter sculpt, being a fighter bomber. We've used this as a bonus for the US when the 2 sculpts when we don't want to use one just for CV duty or the 101s from BOTB for fighters and stukas for fighter-bombing for Germany...
or new sculpts from FMG or AA42...
Dog Fights
When conducting combat, and two sides have aircraft, the aircraft conduct a dogfight in the opening fire stage of combat. Apply normal fighter interception rules. After wards, the planes conduct combat normally with the ground units.
i like this really has grown on me since getting in GC, i personally also like when applying this to other games, like AAP or AAE to allow fighters from adjacent zones to come in for defense duty after an attack is declared....
