And at a game on Memorial Day, no less.

A photo from an Atlanta Braves Memorial Day game has gone viral with one word: RESPECT.

Fans at the game stopped to honor the POW-MIA empty chair. A junior ROTC member stood at attention during the ceremony...and a fan opted to stand up and cover him with an umbrella.

The chair was dedicated last year to honor all of those service men and women who have been unaccounted for since World War I.

Powerful picture.
