Tim Cox of Osceola was a machine gunner with the 833rd in Iraq. In 2007, the armored vehicle he was atop of was blown up by a massive roadside bomb. It nearly killed him. He has spent years recovering from his physical injuries and now battles the darkness that comes with post traumatic stress disorder.
