I like the AWACS, in fact it was a wishlist of mine that got implemented. The only changes I would make is no plane type icon from standard radar, only when spotted by a player in icon range. The AWACS is simulating what you would be reporting in real life, sure its in real time, but still the same data. In a game I don't want to be talking in a MIC to HQ to report everything i'm seeing, so a simulation of it is great.
Maybe could add a button that the player has to press to 'spot' the enemy, like marking it with the box, then its reported to everyone else's map.
