Not a whole lot to add but a word of caution when it comes to protective equipment. I had the opportunity to work with some Navy Spec War types visiting Stennis in the early 90's. Their equipment of choice at the time was Redman. The guy I played with was an instructor with a background in Kyokushinkai, SCARS, and SAFTA. This was before Dieter's CQD so there was a heavy emphasis on striking. As you can guess, the session was brutal and everyone was bruised and bleeding at the end. The point the instructor emphasized to all of us was that protective equipment changes the paradigm of combative defense. We have all seen the RBSD videos showing a "real" knife attack where the bad guy turns into a bull with a sewing machine in his hand while the defender tries to stop the bleeding while backing up. With no protection involved, the defender follows the rules and tries to stop the attack usually by trying to grab. Incorporating protective equipment, the defender now throws ineffectual (usually) strikes again while backing up quickly. The bad guy NEVER responds to the throat shot or the claw hand to face/eyes. I've had the privilege of working with several military H2H instructors but the SEAL's really seemed to emphasize targeting more than the Marines and especially more than the Army. In order to work around the induced "un-reality" of protective equipment, we did a lot of slo-mo drilling to target with enough "dig" into said target to elicit a reaction. Another combative aspect drilled into us was mindset and that was a very insightful lesson in itself.
