n indoor scene within a large, arched-roof structure located in Svetovrachene, Bulgaria. The building features a corrugated metal ceiling supported by visible metal beams. The ground is dark, uneven, and extensively littered with small, white spherical debris, consistent with training ammunition pellets. Approximately 20 to 30 individuals are present, predominantly in the mid-ground. Most are dressed in tactical gear, including various camouflage patterns, plate carriers, helmets, and tactical clothing. Some wear civilian attire or a blend of both. They are standing in groups, appearing to be conversing or preparing. In the foreground, two makeshift wooden tables, likely constructed from pallets, display several plastic water bottles, multiple black hard cases (some open, revealing foam inserts), green camouflage material, and an open cardboard box containing plastic trays. Natural light illuminates the interior, primarily from open sections of the structure, particularly visible on the right side.
