"The Unknown Soldier" is a memorial dedicated to honoring the soldiers who have died in battle without their identities being known. It serves as a symbol of the sacrifices made by all military personnel, particularly those who remain unrecognized. Various countries have established their own versions of this memorial, often located in prominent places like national cemeteries or war memorials. In the United States, the Tomb of the Unknown Soldier is located at Arlington National Cemetery. It was established after World War I to commemorate American soldiers who died in the war without identification. The tomb is guarded 24 hours a day by the U.S. Army, symbolizing respect and remembrance for those who served and sacrificed their lives.
