ARLINGTON, VA - MAY 24: Members of the 3rd U.S. Infantry Regiment place American flags at the graves of U.S. soldiers buried in Section 60 at Arlington National Cemetery in preparation for Memorial Day May 24, 2012 in Arlington, Virginia. 'Flags-In' has become an annual ceremony since the 3rd U.S. Infantry Regiment (The Old Guard) was designated to be an Army's official ceremonial unit in 1948. Every available soldier in the 3rd U.S. Infantry Regiment participates in these events. (Photo by Win McNamee/Getty Images)
