Exclusive interview with Vietnam War veteran and Purple Heart recipient, Robert L. Rice, the author of AWOL in Saigon, Vietnam: The True Story of a Soldier. Rice was wounded in combat and nearly died but was encouraged by an angel he saw on the battlefield. Going Awol several times, doing time in the stockade, getting a Dear John letter, Rice's tour of duty was like a laundry list of nearly everything bad that could happen to a man in a war zone.
