Whilst I agree that the QFI ticket or TP qual are far more attractive outside the Service, I don't think that was the OP's question. QWI is the one whilst one is "in", others may well be better in the "next life". Unless, of course you fancy a spell with defence industry working on weapons and systems.
Can someone tell me what use my C Exam, ISS and WEC are supposed to be to me now?
