A soldier who served two combat tours in Iraq has been arrested for leaving the Army without permission to seek help for post-traumatic stress disorder. Sgt. Brad Gaskins says he left his base in August 2006 because he wasn’t receiving effective treatment from the military. Gaskins had been diagnosed with PTSD and severe depression. Gaskins said, “They just don’t have the resources to handle it, but that’s not my fault.” A CBS News study this week found that more than 6,000 U.S. veterans took their own lives in 2005 — an average of 17 a day.
