Dont know if but or suggestion, but probably only tolerate bug:
Why on radar can be see transport, as one gray icon with 6 others air icons, transport is only one icon, and the other icons are not air, and are in that one. This is unjust intel, who can easy recognite thta transport is coming, when it easyli can be only scout, (interceptor,asf, strat CZAR or big flying spagethy monster).
Same like on carrier isnt see how many plane is in. Its not reason for the same on transport. Radar cant recognize whith air units it is, dont make transport exemption.
That make transport harder to use. and on some situation nearly impossible
