Russian mil-bloggers have laid out basic counter-FPV tactics:
When encountering an enemy FPV drone, it is important to clearly understand that running away from it with equipment and weapons is a virtually impossible task, because an FPV drone can reach speeds of over 100 km/h.
When spotting an enemy FPV drone, it is important to first open fire with single shots. If there are bushes nearby that can be reached with one dash, it is imperative to use them as cover. FPV drones cannot overcome such an obstacle, clinging to the branches of a bush and falling, which, in turn, does not always lead to the detonation of the FPV drone’s warhead.
In the absence of bushes, another slightly less priority cover can be a tree trunk (also located at a distance of one dash), which can be used as a support when firing [Image 2 above].
It is important to remember that if an enemy FPV drone is hit, you must quickly leave the “drone meeting place”, moving as far away as possible and then taking up reliable cover, since the enemy will definitely send several more drones to the place where the previous one was shot down. If your legs are injured, without being able to take the necessary position behind cover [Images 1 and 2 above], you must also fight off the attacking (approaching) FPV drone using the nearest bush or tree trunk (leaning [images 3 and 4] your back on the tree trunk). Attempts to freeze, lie down and pretend to be dead will not help, since drones can hit both the wounded and the bodies of the dead.
