Former Marine Lance Cpl. Josh Onan was in Ramadi, Iraq, in 2006 when his Humvee was hit by a roadside bomb.
"I remember laying down in the truck," Onan said. "Waking up, there's dust, there's debris all over me, and there's an Iraqi colonel who's sitting in the truck with us, and he's just screaming, screaming. I don't understand what he's saying."
Onan suffered a head injury and post-traumatic stress disorder. During the next year, he was in and out of trouble with military officials, mainly for small infractions, which he chalks up to the medications he was taking.
