OMON.

Late at night, when everyone was peacefully asleep in their beds, a security operation was conducted in a multi-story building to detain a suspected group of people distributing prohibited materials. The information was urgent and unclear, but the order remained clear: act quickly and decisively.
In the darkness of the entrance hall, a riot police unit took up position outside the target apartment. A few seconds passed—a brief exchange of signals, preparation, and a dash.
The door flew out of the lock with a dull thud.
The fighters burst inside, instantly filling the narrow corridor. Flashlight flashes, short commands, heavy breathing, and the clanking of equipment shattered the night's silence.
"On the floor! Down, hands behind your head! Quickly!" harsh orders filled the apartment.
Dmitry entered first—disciplined, cool, and completely focused. His face was hidden behind a mask, his gear tightly hugged his frame, and his weapon was held confidently and without unnecessary movement. Behind him were six more riot police officers, who immediately fanned out throughout the apartment, covering the rooms and blocking possible exits.

The security forces didn't yet suspect they had the wrong address. The apartment they were looking for was located one floor below.
