Advertising for this marvelous work states, "a ground-breaking examination of what it takes to perform, cope and survive in the toxicity of deadly combat as a soldier in a foreign land and a police officer in the mean streets of urban America." It really is all that, and more... Outstanding isn't a strong enough word to describe it. If you are a soldier, a police officer, a martial artist, the holder of a concealed weapons permit, or just live in a bad neighborhood you really ought to read this book. Both authors really know what they're talking about, clearly able to articulate hard won wisdom in this well-written and comprehensive tome. Their thought-provoking, insightful work definitively examines every aspect of the psychology and physiology of deadly conflict.
