I loved this course. I am prior military and had a confident demeanor about self-defense; this course made me that much more confident and much more prepared. In the military they teach you by the number's (barney style) which in my opinion had some benefits-I learned defense tactics I didn't already have. However, it is unlikely these "moves" would work in an ambush. Learning spear makes it that much easier because you move naturally. I think everyone, regardless of background can benefit from this course.
