There are currently more than 200,000 active-duty U.S. Marines and another 40,000 in the reserves. These Marines depend on the skills and techniques taught in this concise manual—and now you can, too! This fully illustrated guide features the LINE (linear in-fighting neural-override engagement) system, which is designed to be learned and memorized through repetition. Once the techniques are fully acquired, they should be applied instinctively. The U.S. Marine Close Combat Fighting Handbook explains the methods to quickly neutralize any attacker in close quarters and teaches you how to use any part of the human body as a weapon. It covers breaking a fall, defending against headlocks and chokes, protecting against punches and kicks, surviving encounters with armed attackers, and more.
