Jeffrey Sargent enlisted in the U.S. Army shortly after graduating from high school in 1999. He ended up serving 12 years, including two tours of duty during Operation Iraqi Freedom. During that time, he received a Bronze Star, but also lost several members of his unit, including his platoon leader.
He was a decade into his military career, when during a promotion ceremony to Sgt. First Class, he suffered his first panic attack. It was the initial sign of post-traumatic stress disorder.
