Russian forces have deployed steel mesh resembling volleyball nets on roads around their positions in the occupied city of Bakhmut.
A video posted on Telegram by a Russian observer shows the nets placed at intervals of several meters to block the flight path of First Person View (FPV) drones. A couple of drones can be seen ensnared by the nets.
The tiny drones which have a video guidance system and are small enough to sneak into bunkers and blow up in the face of their defenders have become a menace for both sides in the Ukrainian conflict.
These drones attack moving cars, buildings and bunkers. To attack moving cars, the drone takes a course that coincides with the direction of movement, and dives either after or towards the car. It follows the road to reach buildings and bunkers since they lack GPS or other navigation aids. And nets placed at curves makes it difficult for the FPV drone operator to spot them early and take evasive action.
FPV drones are increasingly being used in conflicts as they are tiny enough to be carried on a soldier's backpack. They can be armed with a small explosive or a grenade and can be guided by an operator who can see what the drone's sensor is seeing and guide the drone to its target.
