One of my ex-UAS students who had been Wokka-ing his way through every single one of Bliar's various wars of recent years was told that he was "too operationally focused" to be picked up for promotion.....

I was once congratulated by the then AOC personally (at an AT/AAR symposium) for my ACR. Nice chap. Didn't help though - I needed another 2 consecutive SRs before getting promotion to SA Sqn Ldr....
