A photo posted on Facebook went viral on social media, and likely especially resonated on the East Coast, where most dwelling in the path of the storm were strongly urged to stay home and indoors.
"Soldiers of the 3rd Inf Reg. continue to stand guard at the Tomb of the Unknown Soldier, despite the worsening weather conditions surrounding Hurricane Sandy," the First Army Division East posted earlier in the day on Facebook, along with the photo.
"The Old Guard has guarded the tomb every minute of every day since April 6, 1948," the regiment posted. "Today will be no exception."
The 3rd U.S. Infantry Regiment, or "The Old Guard," provides ceremonial escorts for the president, for military funerals, and maintains a 24-hour vigil at the Tomb of the Unknowns at Arlington National Cemetery.
The original photo has elsewhere been credited to photographer K.L. Markert, who took it on Sept. 18, 2012.
Arlington National Cemetery is closed to visitors on Monday, along with federal offices and major transportation services in the Washington, D.C., area. Hurricane Sandy has been credited with wind speeds reaching up to 75 miles an hour along the coast.
