Hey bud,
You're correct, Gaziemir does not have any fighter squadrons, it's really a base for the Air Training HQ, in which also the 203. SAR wing is flying CN-235 out of...
Just took some artistic license there and placed a few fighters in too.. That airfield is probably one of the best populated ones on my map.. Lot's of hours went into that design. So whenever you get there take a walk with external cam. :)
I also got Etimesgut, Akinci and Kayseri from your list.. Left out Ankara Esenboga since it's mainly a commercial airport..
For gaming purposes, it's too bad we can't declare an airfield just for helicopters.. Would've been pretty easy to implement, but of course SF isn't for helos or commercial planes in the first place..
Though, I do use the NEUTRAL tag for a few things.. Like the English Akrotiri base on Cyprus, and many of the commercial shipping traffic on the Aegean.. The targets here don't fire back nor any enemy aircraft takes of from the airfields..
