Would it be possible to have AI drones that serve as "scouts" that fly around a predetermined path?
In the real world you didn't only have radar, you always had planes patrolling. In AH, we do not have this luxury because of a lack of people. But we could have AI drones flying around that could report aircraft in bunches of 3+.
I am not sure where they would be reported, or how. I would just assume a system message like "3 Fighter aircraft approaching XXX," "Bomber formation approaching XXX," "2 Bomber formations approaching XXX," etc.
The drones must be within 10k of the fighters to report them in a system message.
Another thing would be to let them get shot down, as this would allow some level of strategic play to neutralize the radar and scouts.
