where am I...

A silhouetted figure holding a rifle stands in a doorway, then moves out of frame, leaving the doorway empty. A man in a beanie and camouflage jacket aims a rifle, followed by a woman in a jacket with a red cross patch kneeling to tend to a person on the ground. A man in a uniform stands with his back to the camera in a dimly lit hallway. The setting is a dark, possibly abandoned building with a bright window or doorway providing backlighting.
