Lieutenant Colonel David A Grossman is the author of On Killing: The Psychological Cost of Learning to Kill in War and Society.  He is also the coauthor of The Two-Space War; On Combat, The Psychology and Physiology of Deadly Conflict in War and in Peace; Stop Teaching Our Kids to Kill: A Call to Action Against TV, Movie, and Video Game Violence; and, The War with Earth.

According to the book description of On Killing: The Psychological Cost of Learning to Kill in War and Society, “Drawing on interviews, published personal accounts and academic studies, Grossman investigates the psychology of killing in combat. Stressing that human beings have a powerful, innate resistance to the taking of life, he examines the techniques developed by the military to overcome that aversion. His provocative study focuses in particular on the Vietnam war, revealing how the American soldier was "enabled to kill to a far greater degree than any other soldier in history." Grossman argues that the breakdown of American society, combined with the pervasive violence in the media and interactive video games, is conditioning our children to kill in a manner siimilar to the army's conditioning of soldiers: "We are reaching that stage of desensitization at which the infliction of pain and suffering has become a source of entertainment: vicarious pleasure rather than revulsion. We are learning to kill, and we are learning to like it." Grossman, a professor of military science at Arkansas State University, has written a study of relevance to a society of escalating violence.”

The Authors said of Stop Teaching Our Kids to Kill: A Call to Action Against TV, Movie, and Video Game Violence, “The goal of this book is to make people aware of what the prolific use of violence in television, movies, and video games is doing to our children. Teaching Our Kids to Kill calls to the table the makers of this violence to address the myriad scientific research on the subject--research that couldn't make it clearer how solid and deadly the link is between this kind of graphic imagery and the escalating incidences of youth violence--and understand and change what they are doing and the dangerous effects their products are having on our children.

Using this book, parents, educators, social service workers, youth advocates, and anyone interested in the welfare of our children will have a solid foundation for effective action. We give you the facts--what's behind the statistics, how to interpret the copious, empirical research that exists on the subject, and the many ways to make a difference in your own home, at school, in your community, in the courts, and in the larger world--so that we all can work together to help end this problem and create a safer environment in which to live. If by doing this we can prevent future Paducahs, Jonesboros, and Littletons, it will be well worth it.”

The According to the book description of War with Earth, “New Kashubia was a planet rich in heavy metals, but utterly lacking in carbon, oxygen, and hydrogen. Even dirt had to be imported at great expense. The colonists, moved there from Earth against their will, lived in tunnels drilled through solid gold but still were the poorest people in the universe. Since their only resource was people, they sent draftees out as mercenaries, fighting in tanks in symbiosis with a highly intelligent computer. And Mickolai Derdowski had fought bravely and brilliantly for nearly a decade, losing many friends in the process, and risen to the rank of General-he thought. But then he found out that it was all in virtual reality. The war had been faked, no one had died, and he was still just a tank commander, not a general at all. But New Kashubia had been well paid by the planet that had hired the mercenaries for the war they had faked, severe food rationing back home was no longer necessary, and people could now afford luxuries like homes and clothing. There was just one problem. A real war was looming on the horizon and this one couldn't be settled in cyberspace. A lot of people might get really, permanently killed.”

According to the book description of On Combat, The Psychology and Physiology of Deadly Conflict in War and in Peace, “On Combat looks at what happens to the human body under the stresses of deadly battle the impact on the nervous system, heart, breathing, visual and auditory perception, memory - then discusses new research findings as to what measures 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 authors reveal the nature of the warrior, brave men and women who train their minds and bodies to go to that place from which others flee. After examining the incredible impact of a few true warriors in battle, On Combat presents new and exciting research as to how to train the mind to become inoculated to stress, fear and even pain.

Expanding on Lt. Col. Grossman s popular "Bulletproof mind" presentation, the book explores what really happens to the warrior after the battle, and shows how emotions, such as relief and self-blame, are natural and healthy ways to feel about having survived combat. A fresh and highly informative look at post traumatic stress syndrome (PTSD) details how to prevent it, how to survive it should it happen, how to come out of it stronger, and how to help others who are experiencing it. On Combat looks at the critical importance of the debriefing, when warriors gather after the battle to share what happened, critique, learn from each other and, for some, begin to heal from the horror. The reader will learn a highly effective breathing technique that not only steadies the warrior s mind and body before and during the battle, but can also be used afterwards as a powerful healing device to help separate the emotion from the memory. Concluding chapters discuss the Christian/Judeo view of killing in combat and offers powerful insight that Lt. Col. Grossman has imparted over the years to help thousands of warriors understand and come to terms with their actions in battle. A final chapter encourages warriors to always fight for justice, not vengeance, so that their remaining days will be healthy ones filled with pride for having performed their duty morally and ethically. This information-packed book ploughs new ground in its vision, in its extensive new research and startling findings, and in its powerful, revealing quotes and anecdotes from top people in the warrior community, people who have faced the toxic environment of deadly combat and now share their wisdom to help others. On Combat is easy to read and powerful in scope. It is a true classic that will be read by new and veteran warriors for years to come.”

According to the book description of The Two-Space War, “It is six hundred years in the future and mankind has learned to move between the stars . . . by going into Two-Space, the vast realm where sentient wooden ships travel beneath canvas sails in a universe that is corrosive to technology. As they charged headlong into the galaxy, humans discovered others who were already there: The elven Sylvans who live in the vast forests of low-gravity worlds, the dwarven Dwarrowdelf who thrive deep in the mines of high-gravity worlds, and other, far more alien races. The ancient Sylvan race is enchanted by the human culture, embracing Tolkien as prophecy and taking "classic" human science fiction as a guide. Against this stellar backdrop, Lt. Thomas Melville's ship is mortally wounded in a cowardly surprise attack. With his captain killed, Melville must capture a feral, sentient enemy ship, then must fight his way across the galaxy to warn of the vast invading armada. In an odyssey of turmoil and battle he forges his ship and crew into a mighty weapon of war and earns the love of an alien princess. Now, if he can only survive the attacks of two very angry alien empires, and avoid being court martialed by his own nation of Westerness for getting them involved in a vast intergalactic war, he might live to enjoy the fruits of his labor.
