I've liked this idea for a long time, the small airfields could be set up without ords and be fighter only,,, grass or concrete shouldn't matter,, originally, I thought of the bases around tank town being this way,, you could rearm a bomb laden plane there, but you have to bring it from a bigger base ,farther away, with ords first!
I've never really understood why we have the three different sizes of airbases, yet everything is available at all of them,, all of the towns are the same size around them so no extra difficulty in capturing those bases.
