To be honest while I have played this game a LONG time, I've just now getting back into running a country. I'm not current in the war game C3 or otherwise.
So really the only thing I can say is fighters with a mix of drones still take out the helicopters, and offensive AA batteries still slaughter the interceptors.
After that it still pretty much seems bomber, or arty and tank work.
I suppose I could test it next time but it's never really mattered to me how many interceptor wings they have other than the ammo I would use, once the helicopters are gone you can drop them like a bad habit.
Just more points for military destroyed.
