The primary "technique" that special forces training uses is just simple exhaustion. It's humbling how much being exhausted can make you re-asses your priorities - and even if you don't quit, you know that you wanted to. Being that exhausted and knowing that rest is nowhere near in your future can be psychologically devastating. The things you listed are probably used, but they're not the primary training method.
I have never been in the military, but I've training Brazilian jiu-jitsu and some mixed martial arts for many years now. Practices can be tough.
