Too true. Having said that, not all ad's for the RAF have to be punchy low level stuff. I quite liked the one with the guy getting over the wall ("only you can push yourself as far as you can go") or something like that.
Was actually alright, and a world better than the crap one of the supermarket checkout guy...
That aside, the sure way to recruit is simply to put lots of good footage of all the guys doing the biz to a decent soundtrack! Would work on me!
