Jim Wagner was Black Belt's 2006 Self-Defense Instructor of the Year for good reason. Through his articles in the magazine and his posts on BlackBeltMag.com, he shared — and continues to share — the fighting lessons he learned in the military and law enforcement. In this book on combatives, Wagner focuses on those military and police martial arts techniques and training methods. He covers threat zones, conflict stances and arm strikes, as well as stopping power, arm blocks using the angle principle, leg strikes and counters, and ways to properly execute the head butt. Legal issues dealing with the use of force are also discussed.
