You are really a great author with great ideas, well thought out, and I think you are already conceptualizing how to achieve him.To avoid a lot of judgment work, can we just categorize all fixed wing aircraft and helicopters into one class (Air Force class) and use only these units as the judgment criteria for this area, and no other units will provide support for the judgment criteria for this area? However, I currently do not have a good idea how to integrate them into OwnedZones, as OwnedZones is occupied by ground units.The first three rules are very correct,The unit must be in the air, This is a very important judgment condition,What about overwhelming numbers?(Regardless of quantity, as long as it exists simultaneously, it is judged as a neutral zone)Who owns it after the last aircraft left?(Due to being previously owned by the blue side, all aircraft will also belong to the blue side after leaving, and ownership will not change until a red plane appears in this area)
