The new weapon against low-flying drones is a metal frame with two modified 7.62 mm machine guns. The machine guns are called PK machine guns or "Kalashnikov's machine gun." They are mounted on the frame with a special sight installed between them.
Interestingly, these types of machine guns are usually found mounted on Soviet-era tanks and other armored vehicles, as well as those made in Russia. However, members of the National Guard of Ukraine converted them to target Iranian kamikaze drones.
The machine gun in the pictures is mounted on a pickup truck and was used by a mobile firing team to take down enemies' drones in Nikolaev region in southern Ukraine.
