A Connecticut veterans’ leader Monday filed a federal class-action lawsuit on behalf of Army veterans nationwide who, like him, were given less than honorable discharges for behaviors later attributed to Post Traumatic Stress Disorder (PTSD). Stephen Kennedy of Fairfield, a lead plaintiff, is a decorated Army veteran and a founder of the state chapter of Iraq and Afghanistan Veterans of America. In the suit, he claims the Army isn’t following a Pentagon policy to make it easier for veterans with PTSD to upgrade their discharge statuses. The suit, filed in U.S. District Court in Bridgeport, is asking the court to order the Army to properly apply the policy. Issued by former Defense Secretary Chuck Hagel, the policy directs military review boards to give “liberal consideration” to veterans whose service-connected PTSD is diagnosed after discharge. A second plaintiff, Alicia J. Carson, a former Connecticut resident who was in the Army and the National Guard and now lives in Alaska, is also named in the lawsuit.
