Rigdon was not a hunter when, at the age of 20, he enlisted in the Navy in 2003. He’d barely ever fired a gun. Football was Rigdon’s thing, and he was a good enough linebacker to play NAIA college ball, at Southern Nazarene University in Oklahoma City. Yet after the September 11 attacks, which he watched on TV in his dorm room, and the subsequent buildup toward the war in Iraq, football struck him as inconsequential. He enlisted, got married, and became the father to a baby girl. She was 18 months old when Rigdon first deployed to Iraq, in 2007, and his wife, Whitney, was pregnant with their second child.
