The chances of service members developing PTSD after military-related traumas is, according to a U.S. study, at least 30 percent. The effects of PTSD can be devastating, ranging, for example, from distressing flashbacks, nightmares, sleep disorders, physical symptoms, irritability, aggressions, memory and concentration problems. These symptoms often cause severe impairment in all areas of life and may lead to despair and hopelessness. PTSD is neither a localized nor a temporary problem. Here, Leah Wizelman relates the true stories of service members from different service branches and ranks from the United States, Canada, Australia, and Germany, who were participants in various wars (Vietnam, Gulf war, Iraq, Afghanistan, Grenada) and peace missions (Kosovo, Bosnia, Croatia, Cambodia, Somalia, Cyprus, Haiti).
