I am glad @HCM used the ALERRT video, as that is where I first heard the term "threshold evaluation". The SIMs testing mentioned in the class is then reinforced with a few dozen SIMs runs by the student. One of my classmates, and my partner for the final exams, was a very recently retired SARC and team leader in MARSOC. He showed me one minor addition that they had been using in Afghanistan, but other than that the ALERRT stuff was really, really well thought of, and in use by a couple of JSOC elements, for reasons @SouthNarc mentioned.
My most recent ALERRT course was taught by a retired JSOC SGM and a couple of recent PMC guys who all liked the program. A lot.
I never got to train with Phil S, but in 1995ish one of my co-workers did. Raved about it for years. He and Louis Awerbuck seemed to share a lot of ideas concerning thought processes during shooting drills.
OP, I hope you find what you are looking for. I also hope you realize the caliber of people trying to help.
I don't expect this thread to last long.
