When you starting mission in air, IFF power switch is in OFF, but IFF works. Bug
IFF hostile/friendly bug happens every time when you switch weapons (Magic, Gun, 530) in CCM lock, not only 530. You need unlock target, switch weapon, select CCM, lock and profit!
I almost shootdown friendly F15 in Blue Flag, thanks to Simple Radio and GCI i aborted missile(530) 2 seconds before impact.:music_whistling:
