His Unit Was Attacked
During a regular patrol in Iraq, his unit was affected by an explosive device. The truck was destroyed and the unit members were all wounded. Luckily, they all were able to get back to the base, despite the fact it was more than 2 miles away from the place of attack. They received Purple Hearts.
He had PTSD and a concussion which were severe conditions. A much worse thing was his car accident back in the United States. It left Raley paralyzed and in a wheelchair.
