Soldiers from the 3rd U.S. Infantry regiment placed flags at every grave in Arlington National Cemetery on Thursday.
The annual flag-in ceremony has been a tradition since the end of World War II. It marks the start of the Memorial Day weekend observances in Washington.
Each soldier places a boot in front of the headstone to make sure each flag is in the proper position.
Even when every little stars and stripes is in place, the 3rd Infantry’s work is not done. The “Old Guard” soldiers will watch over the graves through the weekend to make sure the flags stay put through Memorial Day.
The flags will be removed on June 1.
