Speaking as someone who left recently and as someone who discharged a number of people early in his career, the RAF don't care what you do once you hand in your 1250 and sign the paperwork. They get twitchy if you mention going to work in Iraq/AFG whilst on leave/terminal leave. However ignorance is bliss. The tax man is only interested in you paying tax. Just don't tell the RAF what you are going to do, they can't make you tell them. Take resettlement, leave and terminal leave in that order if you want to stick to the rules. Good luck, it's a tough jobs market out there at the moment
