BCH,
WTF are you on about? If you are not part of the organisation doing the job out of the country in difficult places why should you receive extra pay? This is the question that the x factor does not address.
Tax exemption may well reduce those leaving early, taking option points etc..... oh, silly me the government wants to reduce numbers.
Note to self: Have a word.
ps must fly something big just went bang not very far away.....
