Air bases (prety much all of then except A5, and A15 I beleave) are all but imposable to capture....Why well because their are town buildings in places other than the town which nead be killed in order to effect a capture, they are in the town and scartered about on the field, the tricky things is knocking themmall down and doing it with the time aloted, also the location of all these structures is not know even to me.....O some air bases have two towns...........
