"It was a kinetic and violent deployment. The conditions were pretty austere," Todd said. "My roommate was killed on the first day. ... It shook us pretty bad."
He got his second nickname, "Doc," serving as a Navy corpsman, essentially a combat medic, for the 2nd Battalion 8th Marines in Helmand province in 2009.
"Over there, we were just worried about water, survival, ammunition, food and God," Todd said.
His job was to assist with trauma and injuries on the battlefield. In the end, it was Todd who needed help.
