Although I can perhaps hazard a guess at the type of attributes a non-ex mil person who wishes to fit in might possess, but could you perhaps give me your opinion on what you think a non-mil instructor could do to help himself to make the right moves/noises in such an environment?
Thats not an easy question to answer. When I joined the RAF I went through a number of selection panels and tests and the years of service after that were what shaped me. There is no single thing or even number of things that you could quantity that would make you fit. You either do or you don't' in my experience.
