How about this as a cunning alternative?
Go to theatre, do your job (whatever that may be and whatever risks that involves), return home : no medal.
Do something above and beyond the call: medal
Why on earth should medals be given for simply doing your duty? Why on earth should time in theatre be considered worthy of a medal?
If you really need a piece of ribbon to differentiate between you and some blunty from basingstoke then you really need help.
As for suggesting that crews who sit 8000 miles from the conflict getting medals - good grief! I would be ashamed to even be considered for one if in that position let alone wear one!
