Mainly for our American freinds, our TA special forces can join direct entry, unlike the regular SF where you have to serve in another unit for a few years first. So in the TA SAS there are quite a few 18 and 19 year old troopers. Thats not to say its not a hard selection, as it is, but they can have a warped perspective on military life, and have missed out on the humdrum tedium of regular military life that can be very character building! The combat survival course that is carried out on selection is classed as an instructor course, so by completing it, you qualify as a a combat survival instructor. I would imagine that was what his publicist has woven from his limited military C.V to make it sound a bit sexier. All this said, they do turn immature 18 year olds away and tell them to go and get a bit of life experience, so they do look at phsycological make-up. Have'nt seen the programme mentioned, by the way, cheers, Mark
