As far as the ISR Matrix, it is essentially a control and defense program for LE and professional security with a division between the two. The ISR LE is the focus of the article.
I am just the tackling dummy for the photos. The guy demonstrating is the founder of the program, Luis Gutierrez. I just thought the article came out pretty well and figured you guys would get a kick out of pics of me getting lumped up.
I run a BJJ class separately that is geared more towards civilians wanting to learn SD, get fit and have fun.
