Though more than 300,000 gravesites can be found at this military cemetery, Arlington National Cemetery is probably best known for the Tomb of the Unknowns, the final resting place of soldiers from both world wars, Korea, and Vietnam. This moving tribute is guarded 24 hours a day by specially trained members of the 3rd United States Infantry. John F. Kennedy, William Howard Taft, Robert Edwin Peary, Gen. Jonathan M. Wainwright, Cmdr. Barbara Rainey, Gen. Roscoe Robinson, the McCullough Brothers, 1st Lt. Audie L. Murphy, Margariette Higgins, 1st Lt. Putnam Welles Hangen, Medgar Evers, Thurgood Marshall, and Moses Ezekiel are just some who are interned in Arlington National Cemetery.
