Special Operations Advanced Mountaineer School

Wow.  Never knew this was a thing.  Bet they keep class size low, and I'm betting that its crazy technical.  Selection to attend must be pretty rigorous too.  Can't have a person easily rattled doing goofy stuff on the side of a mountain!

I've never heard of anyone even attending this school.  Is it new or is it one of those secrets that only a select few get to know about.
