I dont know if the course still runs? I did mine in 2000, and it was a good laugh, it was ran at ATR Litchfield, they try to let you experience how a recruit feels ( because you have not been there before!! ).
You are assesed on the subjects you are qualified to teach and you do a BPFA and CFT, I take it by your thread you are posted to an ATR?
Did 2 ATR's mate, Basingbourne and Arborfield, loved it! would love to do it again. Go for it matey, the best tours of my career so far!!
