This is 99% invisible. I'm Roman Mars.

My fellow Americans Memorial Day is a day of ceremonies and speeches.

Throughout America today we honor the dead of our wars.

Whatever you think about Ronald Reagan, they called him the great communicator for a reason.

The unknown soldier who was returned to us today and whom we laid arrest is symbolic of all our missing sons.

This is him in 1984 during a military funeral at the Tomb of the Unknown Soldier at Arlington National Cemetery.

On that memorial day, Reagan was eulogizing the remains of an unidentified service member

from the Vietnam War. The remains would be entombed

alongside three other unknown service members from World War I and two and the Korean War.

It was a big event. That's our own Joe Rosenberg.

A horse-drawn carriage brought the casket to the tomb

past 250,000 onlookers, including hundreds of veterans

who emerged out of the crowd

to walk behind the remains on their way to Arlington.

The most powerful part, though, is when Reagan talks about

who this unknown soldier might have been.

Did he play on some street in a great American city?

Or did he work with sight his father on a farm out in America's heartland?

Did he marry?

Did he have children?

Did he look expectantly to return to a bride?

We'll never know the answers to these questions about his life.
