First... Thank you to every veteran for your service to our nation.

Despite the threat of Coronavirus, The 3rd U.S. Infantry Regiment ('The Old Guard') continues to stand guard over the Tomb of the Unknown Soldier as it has since 1937.

During our current extended stay at home period, U.S. Senator Tom Cotton's book "Sacred Duty" is an excellent non-political outline of the varied service of this amazing unit.

Tomb of the Unknown Soldier remains guarded 24/7 despite coronavirus threat

 
The Army’s 3rd U.S. Infantry Regiment continues to stand guard over the Tomb of the Unknown Soldier, even though Arlington National Cemetery is closed because of the coronavirus lockdown.

“For us, it doesn’t matter if it’s a hurricane, or if it’s the coronavirus.” Cpt. Harold Earls told CBS affiliate WUSA9. “We are always here, we are always guarding.”

Sentinel Earls is part of a tradition that began July 1,1937, and has seen more than 30,000 straight nights of patrol. The gravesite he and fellow servicemen and women guard holds the remains of unidentified soldiers from America’s foreign wars. The first burial was approved by congress in March 1921 and represents unaccounted for U.S. soldiers who lost their lives in WW1.
