Knowing at first sight the exact type of enemy unit, the exact number of men/crewmen, strength of armor, ammo loadout etc. ?
I know that this was a regret for some, but apparently any intermediary solution between 'full instant recog' and 'no recog' would be excessively painstaking to code, if not simply undoable.
OTOH, adding short unrewarding suffixes like "CBU", "ATM", "GBU", "Rkt" etc. about the main carried weapon type, could help you player to choose your aircraft types when buying, without giving away too much info to the other side.
Anyway, as Weeble said, when you are getting an enemy airstrike across your lines, you would start getting this kind of info only too late!
