People seem to think that AWACS and GCI in the real world work like in DCS: an all seing eye that gives you an F10 view of the battlefield.
In '99 NATO agressiom against FR Yugoslavia, USAF pilots found the (British) AWACS next to useless, as it was giving them erroneous reports and, in their words, was making the entire situation more difficult.
Same story on Serbian side with GCI, that was giving reports like: "Blue is comming from the west." No further instructions, no number and type of threat, no height and no speed. Just a one-liner that left the pilots use their imagination and wonder what to do with this information.
