 It's been called shell shock, war neurosis, and battle fatigue. Today, we call it post-traumatic stress disorder, and it affects one out of every five warriors returning from battle in Iraq and Afghanistan. The Wounded Warrior Project offers comfort and support for warriors with PTSD and all other scars of war, whether those scars are visible or hidden. Find out how to help, because for warriors, the greatest casualty is being forgotten. Please visit WoundedWarriorProject.org.
