"This new book is what our young warriors need. At one of David's last briefings a Senior NCO approached me and said, "Sir, the army spent 18 years and thousands of dollars teaching me to kill. This is the first time I have been taught how to deal with it." This book will allow those not fortunate enough to hear David do their own preparation for the ultimate test." Lt. Col. Hal McNair Professor at the Joint Spec Ops University
