The book you hold in your hands is a powerful tool in the arsenal of our SoldiersÕ well-being and, in some cases, very survival. Since our nation began putting Soldiers in harmÕs way, our forces have experienced the psychological trauma of war. In some cases, the number of casualties due to psychological injury approached the rates of physical injury. As leaders, we spend countless days training our Soldiers to survive the actual battle. Combat training, battle drills, physical fitness, and medical readiness help ensure their physical survival and ultimate victory in the combat zone. Now, we dedicate ourselves to helping ensure their psychological survival and victory when the battle is over. In memory of the 248 Soldiers of Task Force 3Ð502 who perished when their plane crashed on December 12, 1985, in Gander, Newfoundland, as they were returning home from peacekeeping duty in the Sinai. And in honor of all of those who continue to fight and sometimes die in the cause of world peace and security.
