I did see a show on OLN called SAS, are you good enough. It has some real ex SAS put some non military people through a selection course teaching them various skills. They would eleminate people at regular intervols and at the end the staff picked a winner. It was well done and the staff were no **** SAS. The kicker was no one was allowed to have military experance. It was intresting to see some "pro athleats" go to crap because they didn't have the gee whiz gear. Military issue only. Some did quite well. Men and women were allowed in.
Another similar program with Eric Haney aired in the US as well. The diffrence was they concetrated on mental skills more than physical.
