John Perkins has been training and teaching martial arts and self-defense for over 50 years. He has taught hand-to-hand tactics to Marine combat units, Marine scout sniper units, and military counterdrug forces. He also has instructed law enforcement personnel from the FBI, New York City Police Department, New York State Police, and the New York City Transit Police. A former bodyguard to Malcolm Forbes and Israeli Defense Minister Moshe Dayan, Perkins is a forensic crime scene expert and a master handgun instructor and marksman. He has extensive experience in the martial arts of hapkido, taekwondo, kyukushinkai, kempo karate, judo, jujitsu, goju, and tai chi chuan. He has trained in Native American fighting principles since the age of five. Perkins has battled in unlicensed pit fights, a savage forerunner to today’s Ultimate Competitions. He is the founder of guided chaos, an adaptive, internal-energy art whose principles are detailed in this book. Perkins’ system is recognized by the International Combat Martial Arts Federation, through which he holds a fifth-degree black belt in combat martial arts. Perkins lives in Nyack, New York.

An all-conference wrestler in high school who later learned boxing in the Marine Corps, Ridenhour is also a sixth-degree master in guided chaos. He is a veteran of Operation Iraqi Freedom and the Gulf War, where he commanded a 50-man infantry unit and served as an instructor in unarmed combat for his Marine unit and for the battalion’s scout sniper platoon. He has also worked with various law enforcement agencies, U.S. Customs, U.S. Border Patrol, and the Drug Enforcement Agency during counterdrug missions. He is a member of the International Combat Martial Arts Federation. Ridenhour lives in Hartsdale, New York.
