Since World War I, more than 92,000 American troops are unaccounted for. 

In honor of America's prisoners of war and those missing-in-action, Ohio State installed an unoccupied seat and plaque in Ohio Stadium.

Here's a look at the seat and plaque, courtesy of Urban Meyer's Twitter account:

A stirring and fitting tribute, indeed.

According to the plaque, Ohio State will christen the memorial this Saturday when it takes on Bowling Green in the first game of the 2016 season.
