In this Oct. 14, 2009 photo, Richard Martin, a wounded Iraq War veteran, works in his office at Northrop Grumman in Clearfield, Utah. Martin suffers from TBI (Traumatic Brain Injury) from several blasts during his deployment and uses headphones in his work to help his concentration as well as block out unexpected noises. Martin also sticks post-it notes to his walls, and utilizes a blackberry to help remember tasks related to his work. Army officials say many new veterans suffering from PTSD and brain injuries struggle to find and keep a civilian job. (AP Photo/Steve C. Wilson)
