The Tomb of the Unknown Soldier literally recognizes and honors unidentified veterans. In war (especially many years ago), sometimes the combatants cannot be identified. These people are commemorated at national monuments that are often known as the Tomb of the Unknown Soldier. There are several of these tombs throughout the world. In the United States there are three: • The Tomb of Unknowns in Arlington, Virginia • The Tomb of the Unknown Revolutionary War Soldier in Philadelphia, Pennsylvania • The Tomb of the Unknown Confederate Soldier in Biloxi, Mississippi

Unknown soldiers are not limited to just 4 wars. In every war there are going to be at least some participants whose identity is never determined. Wars are by their nature very chaotic. But as far as the United States is concerned, the most significant wars were the Revolutionary War, the Civil War, WW I, and WW II. Perhaps those are the ones you are thinking of.
