that is what happend in the war - the fighters covered the navy or assisted in the amphib. the defender only gets to choose one defensive action and the navy is in his adjacent sea zone, he decides whether to attack the navy or wait to attack the first round of ground units. One way to help this --
Normally air units can not be destroyed by ground troops and will be used to possibly destroy as many units as possible, knowing they can't be destroyed; however I have toyed with the idea of - if you attack with it or defend with it, it has the possibilitiy of being destroyed. Example - the attacker has 3 inf and 3 aircraft, the defender has 2 inf and 2 aircraft - the air to air both whif and move to the battle board - the attacker or defender rolls more hits than the number of infantry, the excess hits are applied to the air -makes players think about using the air ken
