The Russian Burevestnik unmanned aerial vehicle regiment unveiled a prototype of a homemade system for countering fiber-optic-controlled FPV drones. These FPV drones are known to fly along designated corridors, making them convenient and safe to operate. Barbed wire is strung across the drones' path in fields, and a motor is mounted on the end of the installation to rotate the wire. As the drone flies past, its control cable descends to the ground and hits the wire. As the wire rotates, it entangles the drone's communication cable and sever it. The device is simple and quite effective, and it is already in use. However, it is not yet in mass production.
