2 Best Courses You've Ever Taken in the Army - GO

What's up everyone. Coming up on the end of my contract and due to high ACFT, high performance in my contract, and a bit of negotiating, I have the choice of any 2 schools in the army for my reenlistment. The only exclusion is Airborne because I'm not in an airborne unit and the state (I'm ARNG) can't send anyone to airborne who isn't in an airborne unit, which for us, is the MICO.

I'm trying to decide what I'd like to pick up. I'm interested in mountain warfare (been rock climbing since I was 8, plus the Ram's Head device would be sweet) and arctic classes, but I'm open to anything. What are the best courses you all have taken?

Edit: Some context. I'm E-5 46S assigned as an M-Day soldier in the Army National Guard. Not specifying state because public affairs is a super small world. I'm a firefighter/paramedic civilian side for whatever it's worth for context's sake. I'm also a dirty slut for uniform candy, so bonus points for that but I'll do anything cool ig.

I'll just take a small fry and some chick fil a sauce if you've got some
