Sean Parnell is a veteran and a New York Times best-selling author of Outlaw Platoon: Heroes, Renegades, Infidels, and the Brotherhood of War in Afghanistan. Parnell is one of Trump’s favorite candidates, so it makes sense that Trump had him speak at the RNC Convention in 2020.
Sean Parnell served in Afghanistan as an Army Ranger for the U.S. military. In 2006, he was wounded in action and suffered a traumatic head injury. He was medically discharged from the army in 2010 and retired as a “highly decorated Captain and was awarded two Bronze Stars, one for Valor, and the Purple Heart.”
