Jock,
Dont discount the value of the old boy network. Reputation does count for a lot, and when you apply for a job, if there is any ex-mil connection someone is going to talk to a friend of a friend who will have been on a Squadron with you.
Anyone who has flown green machines (or, if you must, grey ones!) knows the rigours of training and selection, and knows that they get a fairly predictable product if they hire you. You just need to find all your ex-mil mates now and get the beers in!
