Seem to remember the fit as !!!! blokes were never available for any detachments / war zones. Due to the fact they were always representing station / RAF in sports competitions, or too busy training for aforementioned competitions.
Hmm decisions do we send SGT 'A' to a sandy place for 6 months or do we keep him in the UK so he can play for Scotland in the 6 Nations.
Forget it send the fat !!!!
