The image depicts a classroom or lecture hall within a military educational institution in Dolna Mitropolia, Bulgaria, likely the Georgi Benkovski Higher Air Force School. Approximately six to eight individuals are visible, predominantly male, seated at light-colored wooden desks, viewed from behind. Most attendees wear digital camouflage uniforms. In the immediate foreground, the back of a person in a digital camouflage uniform is visible, with their left shoulder and the top of their head in focus. To their right, a partial view of another person in a similar uniform shows a sleeve and a military-style cap resting on the desk. On the desk in the mid-ground, a plastic bottle of Devin brand water, a black fabric bag, a smartphone, and a patterned pencil case are present. At the front of the room, a male instructor in a dark uniform stands beside a large white projection screen. The screen displays a presentation with text in Bulgarian, including "Как се мери разстояние?" (How is distance measured?), and a visual showing planets and astronomical distances, specifically "1 Light = 299,792.458 km". A black projector is mounted to the ceiling above the screen. The instructor is looking towards the audience. The classroom features light-colored walls and a white ceiling equipped with linear fluorescent light fixtures and a small white ceiling-mounted device, possibly a smoke detector. The overall scene shows a formal instructional setting with military personnel as students.
