The photo behind Sheller is called "The Column", it is a part of the Korean War Memorial and is located on the southwest portion of the National Mall, not far from the Lincoln Memorial, and south of the reflecting pool.

Here is a photo taken during the summer time, and a little further back than the photo above.

Comms... if it is it would be to combat vets.

All four services (of that day) are represented, Army, Navy, Marine, and Air Force.

Cold full moonlit winter nights, during snowfall, or a winter lightning storm... this part of the Korean Memorial calls out to you.

Did not find the photo on the wall behind Sheller on line.
