A small step for man, a giant leap for those wanting to honor war dead

The Tomb of the Unknown Soldiers, actually there are three soldiers at rest there, is one of the most hallowed sites in the country. It’s also one of the most popular visitor attractions at Arlington National Cemetery. Next month the cemetery will mark an important date. For details I caught up with the commander of the soldiers who guard the Tomb of the Unknown, First Lt. Andrew Katz.
