ARLINGTON, VA - MAY 26: U.S. Army Col. David Astin salutes the headstone of a fellow solder he fought with in Afghanistan in Section 60 at Arlington National Cemetery during Flags-In May 26, 2011 in Arlington, Virginia. "Flags-In" has become an annual ceremony since the 3rd U.S. Infantry Regiment (The Old Guard) was offered 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) less
