U.S. Marine Sgt. Marcus Martin, a 32-year-old squad leader with Guard Force Platoon, 3rd Battalion, 3rd Marine Regiment and native of Charlottesville, Va., practices Pashto with Afghan boys while providing security outside the district center on Nov. 28. Guard Force isn't a traditional infantry platoon. It's a melting pot of Marines from various occupational specialties that functions as the main security element for the battalion headquarters at Forward Operating Base Delhi. (Cpl.
