I don’t see how a company that can do all this (or train people to do all this) can be called a mere security company.

It is interesting to speculate what this vast increase in the number of people who are skilled in close quarters combat means for the future. Heck, there are plenty of places that will teach civilians a lot of these skills even if they have no connection to the government.

Close quarters combat is the true martial art of our age (in the original meaning of the term) and it is worth remembering that most martial arts were perfected in times of utter chaos that followed the breakdown of authority.
