Hey man, as you probably know SUT is going to be changing and there will not be as much patrolling as there used to be. So, a lot of advice you get may be based on the "old" SUT. I got the book written by Paul De LaFavor, who was actually one of the oak grove cadre at SUT, and looked through the ranger handbook. There are some little differences in the ranger handbook and SF tacsop if you've gotten your hands on one of them. Some little things are different though, for example the bravo team leader runs squad ambushes now.
But what helped me succeed was by doing man. I got out into the woods with my buddies before leaving just to have some practice running ambushes and walking through the woods. When class came I was a sponge, volunteered as much as I could, and focused on being a good teammate. When in leadership roles I was loud and aggressive and made sure my guys were good and we were all on the same page.
PM me, I still help buddies out by going out into the woods behind Ritz Epps and walking them through some stuff. Good practice for them and I can always use more reps, would love to have you out there too.
