I was told but have never verified

that those with a wrestling background have the highest pass rate compared to other sports for special operations schools in the military (SFAS, Ranger school, BUD/S, MARSOC A&S, etc.). Swimmers are supposedly second, even excepting BUD/S. I 100% believe it just from observation.

The best soldier I ever came across was a college wrestler. He was smart and disciplined and beyond crazy. He could donkey kong climb (dual rope) a 35 foot wall like it was nothing, among many other things. Spent most of his career in special operations of various sorts.
