@marshmallowofwar thanks to both you and @AndrewAAGamer for clarifying. Thought I had a sneaky way to slow him down, but will have to give it some more thought!
I realize that Eire is useless. The irony is the fact that the easiest, and perhaps the most realistic (as in won’t attack a true neutral) way for France to capture a territory is for it to capture something that doesn’t matter, underscoring the dismal state of France in general.
The rules for scrambling specifically state that you may only scramble if combat is occurs in the sea zone surrounding the island with the air base. This combat may be either a straight naval battle if defending naval units exist in the sea zone or just an amphibious attack launched from the sea zone if there are no existing defending naval units.
