Not even just them, I suspect most Army and Marine infantry are more than capable of handling this kind of training.Not to mention that ignoring the training and service of the rest of the SOCOM community and just honoring the previous experience of the JSOC guys seems pretty demeaning. I guarantee you that just about every SEAL, Ranger, and PJ out there are way more qualified to run the course than some guy who "took two courses".
I mean there are thousands out there with several deployments that I think could handle this class. Hell even some SWAT team members are probably pretty capable.
