National Guard's 1st Platoon, 273rd Military Police, performs preventive maintenance checks on several HUMVEES on Wednesday, Jan. 18, before he and his fellow soldiers drove them to the D.C. Armory in preparation for the 58th Presidential Inauguration. His unit will assist the D.C. Police in keeping order. "It's a truly great honor to be part of history," he said.
