As well as pilots should learn BASICS of ATC. 95% of them has no knowledge of what's going on in operations room.
I spend more time in a plane's cockpit a year than most pilots in operations room during their career.
For over 10 years of my work in ATC I've seen maybe 5 pilots upstairs. 3 of them were interested in view from the tower, 1 had some complaints, 1 was part time ATCO, part time airline pilot.
4 of them were asking no questions about the airspace and rules of the job, guess which ones?
As for the USAF plane: do you really believe that ALL controllers should know ALL aircraft performance up to one knot?
What's wrong with 255kt BTW? I am reducing to much smaller numbers every day
