Kill or get killed (US Navy combat manual)(1976, 1991)

This is the best and longest-selling book on close combat in history. Reprinted and in current use by the U.S. Marine Corps as an official training manual, it details methods of self-defense, offensive close combat, combat shooting and crowd-control techniques in riot situations. Colonel Rex Applegate is widely regarded as the father of modern close combat and combat shooting, and this book is considered the standard by which all other books on the subject are judged.
