I always used to judge Valley as the best mil ATC I had ever encountered. I guess they were helped by the fact that it was so busy, they got a lot of practice! And I guess the fact that most of the flying was syllabus-driven and cyclical would have helped them get into a groove as well.
Some of the current front-line bases, whilst not as busy, have a much more 'random' variety of stuff going on (pre-deployment training, exercises, etc) even when there's just one type based there - which makes it harder for ATC to be as crisp.
Jeez, never thought I'd see so many RAF aircrew leaping to praise and defend our ATCers. You certainly won't hear any of that in the crewrooms or Mess bars!
