ARLINGTON, Va. - President Joe Biden, first lady Jill Biden, Vice President Kamala Harris and second gentleman Doug Emhoff came together for a somber ceremony at the Virginia cemetery’s Tomb of the Unknown Soldier, which is dedicated to deceased service members whose remains have not been identified.
Perched atop a hill overlooking the nation’s capital, the Tomb of the Unknown Soldier at Arlington National Cemetery is a monument honoring the brave U.S. service members throughout history whose remains have not been identified.
The iconic memorial has been continuously guarded 24 hours a day since 1937 and depicts three carved Greek figures representing peace, victory and valor on its marble stone. Inscribed on the back of the tomb are the words: "Here rests in honored glory an American soldier known but to God."
The monument, which welcomes thousands of visitors each year, is the final resting place for Unknowns of World War I, World War II and the Korean War.
Tomb guards, who are members of the 3rd U.S. Infantry known as the "Old Guard," maintain a constant vigil day and night at the monument to ensure the Unknowns will forever rest with dignity and honor.
"There are families out there that will never have closure," said Sentinel Spc. Preston Millison, 3rd U.S. Infantry Regiment (The Old Guard), who has conducted more than 600 walks guarding the tomb. "That soldier has gave absolutely everything, and there is nothing more for him to give."
The monument’s history dates back to 1921, when Congress approved the burial of an unidentified American soldier from World War I in the plaza of Arlington National Cemetery's new Memorial Amphitheater. The WWI "Unknown" arrived in Washington, D.C. in November of that year and lay in state at the Capitol Rotunda — with thousands of visitors lining up to pay their respects, according to Arlington National Cemetery's website.
The casket was then transported to the Memorial Amphitheater, where President Warren G. Harding placed the Medal of Honor and Distinguished Service Cross on the casket, and foreign dignitaries added more medals.
It was eventually lowered into the crypt. A bugler played "Taps," followed by the battery firing a 21-gun salute, and "the Unknown Soldier was home," the cemetery’s website reads.
Many people visited Arlington National Cemetery in the following years to pay their respects at the Tomb of the Unknown Soldier, which soon came to symbolize the sacrifices of all U.S. service members.
And while many respectful mourners flocked to the tomb, so did tourists who left trash strewn around the site, as well as photographers who set up shop at the tomb and charged people to take their picture, according to Arlington National Cemetery.

This led Congress to establish a military guard to protect the tomb. And since July 2, 1937, those interred at the Tomb of the Unknown Soldier, also known as Tomb of the Unknowns, have never been alone. Sentinels of the 3rd U.S. Infantry later assumed these duties in 1948 — maintaining a constant watch regardless of weather conditions.
Millison, who holds badge number 633 and conducted his last walk in 2016, said the monument helps visitors walk away with "a new meaning of what it means to have sacrifice and dedication to something greater than one’s self."
"When you come here and you watch the tomb guards and you see the surrounding cemetery, the sea of white headstones, it really brings home a higher understanding of what your role is in this country and how fortunate you are to be in this country," said Millison.
Working 26-hour shifts that begin around 4 a.m., Millison described it as "one of the most serious jobs you can have."
Between hourly changing of the guard ceremonies, the tomb sentinels follow a meticulous routine when watching over the graves, including marching 21 steps down a black mat, turning and facing east for 21 seconds, then turning and facing north for 21 seconds, and then retracing the 21 steps. The number of steps symbolize the 21-gun salute.
The tomb guards are perfectionists, polishing their shoes and conducting other duties like clockwork.
"It’s just like a band of brothers," Millison said. "Everybody’s got each other’s back, no matter what."
Today, the sarcophagus built above the tomb of the soldier who served in WWI sits in front of the three marble slabs that identify the crypts of the soldiers from WWII and Korea, as well as all missing U.S. service members from the Vietnam War.
The sentinels not only guard the Unknown Soldiers, but also everything around the nation’s most hallowed ground.
"We’re here to guard and safeguard everything here, including the family members, the veterans," Millison explained. "Everybody here is under our protection. And every soldier that is buried here, and every family member that is buried here will always be guarded by us, no matter what."
Arlington National Cemetery is the final resting place of more than 400,000 men and women, including U.S. presidents, flag raisers pictured on Iwo Jima, and Civil War generals.
"You really see the sacrifices that have been made for this country," Millison said. "You can go anywhere in this cemetery and there are people interred here from all the wars from America’s history."
Millison said the job makes every tomb sentinel "hit their wall," but those who are able to keep going have what it takes to stand guard.
"I hit my wall three times," Millison said. "But each time I just tried to pick up the pieces and keep going because in the end it’s worth it."
