Lance Cpl. Nicolas McDonald sits in a humvee similar to the one stuck by an improvised explosive device while traveling outside the city of Fallujah in March 2006. The heavy equipment mechanic with Maintenance Company, Combat Logistics Battalion 5, 1st Marine Logistics Group, suffered a concussion and a perforated ear drum due to the force of the blast. The 20-year-old Yucaipa Calif. native has extended his tour to stay in Iraq an additional six months.
