This is perhaps one of the more stunning pictures we've come across today:
According to the First Army Division East, which posted the picture today on its Facebook page, the three soldiers of the 3rd Infantry Regiment stood guard at the Tomb of the Unknown Soldier as the first heavy bands of rain from Hurricane Sandy moved across the Washington, D.C. area.
"The tomb," they write, "has been guarded continuously since 1948."
The U.S. Army has more information on the tomb.
Update at 12:50 p.m. ET. More Photos And Background:
Back in 2011, during Irene, the Old Guard stood watch over the tomb. As Mark reminded us at that time, "there is a shelter the soldiers could use, but they have consistently declined to do so."
Also, the 3rd Infantry Regiment has posted a few more pictures on its Facebook page.
