Though it's been 20 years (good god!!), the Mountain Warfare School at CP Ethan Allen in VT was pretty damn good. Two phases, summer and winter with each phase lasting two weeks. After completion of both phases, one is awarded the Ram's Head device, only authorized for wear in Vermont.

The Army's mountain/ winter warfare school in in Alaska and is 6-weeks long. Don't know much about it since I've neer been there but I'm told it's pretty good.

Last I knew, the only unit in the 86th IBCT that was an actual mountain unit was 3-172d INF...had lead climbers, assault climbers, etc. Not sure if that's the case now.

It'd be great if every one of our light infantry brigades had at least one company dedicated as a mountain unit. It's great that we send so many of our joe's to jump school but mountain training has a more practical application.
