The skies in the Vovchansk direction, where the "Hart" border brigade is carrying out combat missions against russian occupation forces, are swarming with enemy "birds"—reconnaissance drones, strike UAVs, and kamikaze drones. While spotting them during the day is easier, it becomes much more challenging at night. This is where Mobile Fire Groups (MFG) come into play. They constantly go on night patrols, and the ZU-23-2 anti-aircraft gun, in skilled hands, performs exceptionally well.

Watch as the anti-aircraft gunners of the "Scorpion" unit detect enemy drones in the night sky, with commentary from the Mobile Fire Group commander, codenamed "Yarema."
