Not sure if this is being aired in Canada yet, but I've been catching "Surviving The Cut" over here on Discovery. Basically its a series that follows about 7 or so of the U.S. military's top training courses. So far, they followed:
-Para Rescue Jumper
-Marine Force Recon
-Marine Scout Sniper
-SF Combat Diver
and there a few more as well I think. Great series, gives one a better sense of what its like just getting to the start line.
