Grand Slam honor guardsmen carry the U.S. League of Families prisoner of war and missing in action flag before raising it over a memorial at the 379th Air Expeditionary Wing in Southwest Asia, Sept. 20, 2013. The league’s flag has been flown over the White House on National POW/MIA Recognition Day since 1982 as a symbol of commitment to those who are still prisoners of war and missing in action.
