The Known Unknown

ROMAN MARS
About this episode

The tradition of the Tomb of the Unknowns goes back only about a century, but it has become one of the most solemn and reverential monuments. When President Reagan added the remains of an unknown serviceman who died in combat in Vietnam to the Tomb of the Unknowns in Arlington National Cemetery in 1984, it was the only set of remains that couldn’t be identified from the war. Now, thankfully, there will never likely be a soldier who dies in battle whose body can’t be identified. And as a result of DNA technology, even the unknowns currently interred in the tomb can be positively identified.
