In this essential new book, self-protection expert and former military intelligence officer Tim Larkin changes the way we think about violence in order to save our lives. By deconstructing our assumptions about violence - its morality, its function in modern society, how it actually works - Larkin unlocks the shackles of our own taboos and arms us with what we need to know to prevent, prepare for, and survive the unthinkable event of life-or-death violence.

On Combat looks at what happens to the human body under the stresses of deadly battle and the impact on the nervous system, heart, breathing, visual and auditory perception, memory - then discusses new research findings as to what measure warriors can take to prevent such debilitations so they can stay in the fight, survive, and win. A brief, but insightful look at history shows the evolution of combat, the development of the physical and psychological leverage that enables humans to kill other humans, followed by an objective examination of domestic violence in America.

The revised and updated edition of Lt. Col. Dave Grossman's modern classic about the psychology of combat, hailed by the Washington Post as "an illuminating account of how soldiers learn to kill and how they live with the experiences of having killed". In World War II, only 15 to 20 percent of combat infantry were willing to fire their rifles. In Korea, about 50 percent. In Vietnam, the figure rose to more than 90 percent. The good news is that most soldiers are loath to kill.

These days, no one in America feels immune to violence. But now, in this extraordinary, groundbreaking book, the nation's leading expert on predicting violent behavior unlocks the puzzle of human violence and shows that, like every creature on earth, we have within us the ability to predict the harm others might do us and get out of its way. Contrary to popular myth, human violence almost always has a discernible motive and is preceded by clear warning signs.

True toughness involves far more than what most of us believe and has far greater influence on our success and fulfillment than we imagine. Toughness is defined by four interdependent elements: Character - who are you and are you secure in your identity? Capability - what are you able to do? Capacity - what are you able to withstand? And commitment - what are you willing to do? Being truly tough is a genuine command over ourselves and an ever-increasing mastery of the mental, emotional, and physical elements that define us and determine the course of our lives.
