This book is not just fun reading for determined riflemen, but vital self-defense info. for all security ranks and jobs. The Pentagon lost on the ground 40 years ago, and its squad tactics haven't changed much. Herein lie more advanced techniques for every category of short-range combat. They will permit better small-unit maneuvers (and fewer losses) for every intensity of combat. As Western ordnance turned more lethal, Eastern armies came to rely on tiny semi-autonomous elements. Most provide every rifleman with guerrilla training. Until the Pentagon follows suit, its own infantry enlistees will have less field skill, initiative, and decision-making experience than their Communist counterparts. In any close encounter, they will die unnecessarily and their commanders suffer too many casualties.

After Last Hundred Yards, probably H.J. Poole's best.  A must read for infantry.  The publisher additionally recommends this book to all non-infantry, law enforcement, and security personnel.
