Retired Senior Master Sgt. Bob Greene, American Legion Post 6 commander, gives some quick instructions to a group of volunteers on where to place U.S. flags at Memorial Cemetery in Grand Forks, N.D., on May 22, 2015. More than 200 base airmen and family volunteers observed this year’s Memorial Day by placing small flags over 32 acres of cemetery plots that serve as the final resting place for more than 1,000 U.S. servicemembers. The U.S. flags placed at Memorial Park Cemetery (by South Columbia Road) were provided by the Legionnaires. (U.S. Air Force photo/Staff Sgt. Luis Loza Gutierrez)
