What was Tomb of the Unknown Soldier about?

Answer 1

The Tomb of the unknown soldier is to honor all of those soldiers who have fallen, but have not been honored. It is basically a blanket honoring to all of those soldiers who have died protecting their great nation.

Answer 2

To honor all the soldiers that fought in World War 1,2, or the Vietnamese wars but whose bodies could not be identified, thus each soldier is "unknown" (now, in death).

Every soldier was issued Dog Tags (ID tags) when each enlisted. The reasons a soldier could become an "unknown soldier" are numerous, but involve not having the Dog Tags or ability to recognize a face/identity. Some reasons soldiers become "unknown" include:

• Having died, been buried overseas, but by the time US Military located the grave the man's Dog Tags had been separated from the remains. Remains may have only been bone fragments after decades.
• The enemy took the Tags and identifying papers (if any) as a "souvenir", and there was no way to ID the remains.
• Dog Tags were damaged in battle (gunshot; bomb; etc.).
• The body (and tags) were totally mutilated by bomb, grenade, trip wire, "Bouncing Betty", etc.
• DNA testing had not begun in those years. (Some families seek DNA testing in recent years to try to ID soldiers, looking for their loved one.)
• Some people claim that US investigators did not do enough to ID the soldiers, especially after the Vietnam War.
• (maybe other reasons I'm not aware of yet)
