This FSB operative is using the Belarusian made Groza-R quadcopter killer. Produced in large numbers for export, this is the perfect deniable anti-drone weapon. The weapon works by forcing the drone to land, or moving it at high speed into an object. Both outcomes have the same effect!
He carries a suppressed MA compact assault rifle, chambered in 5.45mm for personal protection. Under his civilian clothing, he is wearing a concealable anti-fragmentation vest, with an apron which can be stowed under his jacket.
