The Military Helped Him Succeed as an Actor
Even though Adam was never an athlete or joined any kind of organization that had a sense of fraternity, he easily adapted to Marine Corps culture. The Marines gave him structure and unity he never experienced before. He trained hard but looked forward to getting deployed with his friends. But he had an unfortunate accident that ended up changing his plans.

Adam got into a mountain biking accident before deploying and injured his sternum. He tried to lessen the pain and his debilitated state by training even harder than before. Which was like only really done to show that he was okay. (Is that a guy thing?) Anyway, after two years of service with no actual time in the field, the young marine was medically discharged.
