ARLINGTON, Va. -
Every year, a special group of soldiers marks Memorial Day on hallowed ground.
Members of the 3rd U.S. Infantry Regiment, known as the "Old Guard," place American flags on every gravesite for service members at Arlington National Cemetery in Virginia. The tradition, which is known as "Flags In" has been carried out for more than 60 years.
In all, more than 228,000 of the small flags are placed near each headstone by the measure of the soldier's boot length.
Flags are also placed at the graves at the Soldiers and Airmen's Home National Cemetery. Read full story here
