Most Cost Effective Way of taking out C3 Air Force (Kebir Blue)

I have read the forums and heard time over time that the 1kFP/1kAD Combo. The AD will take all the hits, (and I found out that they don't actually attack air units).

What about using 1k NFP? or 1k OAAMB with 1k MRMBs?

And for clearing defense garrisons, (after air of course) using 1k MRMB with 1k ATMB? or the 1k HA with 1k HT? or just using precision bombers?

Use Fighter-Bomber Combos Unless you are within 1500km of the c3 you want to take out. Make a wing with 1000 Fighters of 250 Quality. Use 710 Bombers of 100Q. Ammo 100 Quality. You should have enough bombers in that Air Wing to destroy all the interceptors of a level 3 c3 and have enough bombers left over to clear all defenses too.

If within 1500km, use high Quality drones 150-200 and 250 Quality Fighters with 100 Quality Ammo, this will make your Fighter-Drone wing fighting Quality good and will reduce your losses.

Bombers are expensive, but very useful.

When clearing defensesIf you can afford the extra wing only) For ease I would use only bombers. There are other added benefits to this than meets the eye. I'll let you figure it out. Make a bombing wing with 710 Bombers 100 Quality. Again use 1000 Attack drones 250 Quality to avg the unit fightin
