The photo behind Sheller is of a portion of the Korean War Memorial that is called "The Column". The memorial and these statues of a patrol of U.S. service men during the Korean War 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.
