Defense Secretary Chuck Hagel accompanied by U.S. Army leadership inducted 24 Army veterans into the Pentagon's Hall of Heroes in the Pentagon Auditorium, Arlington, Va., March 19, 2014, as part of the festivities surrounding one of the largest Medal of Honor ceremonies in history. Each of these Soldiers' bravery was previously recognized by award of the Distinguished Service Cross, the nation's second highest award; that award was upgraded to the Medal of Honor. Congressional review and the 2002 National Defense Authorization Act (NDAA) prompted a review of Jewish American and Hispanic American veteran war records from WWII, the Korean War and the Vietnam War. During the review, records of several Soldiers of neither Jewish nor Hispanic descent were found to display criteria worthy of the Medal of Honor. The 2002 NDAA was amended to allow these Soldiers to be honored with the upgrade - in addition to the Jewish and Hispanic American Soldiers.
