This was reported by Foreign Policy with reference to an official representative of NATO.
The publication writes that FPV drones are equipped with cheap cameras, which make it difficult to aim at night or in cloudy weather, and often carry homemade ammunition, which sometimes explode in mid-flight or fail at all.
Analysts interviewed by Foreign Policy believe that FPV drone attacks on Russian tanks have mixed results.
Rob Lee, a senior fellow at the Eurasia Program at the Institute for Foreign Policy Studies, says the overall accuracy of FPV drones is less than 50%, and in some cases it takes 10 or more drones to destroy a tank.
At the same time, Lee notes, Russia is running out of armored vehicles and tanks, so if the current dynamics on the battlefield are maintained, Moscow may lose its numerical advantage in tanks and make it difficult for itself to conduct offensive operations in the future.
"The problem is that Russia receives a lot of manpower," the analyst emphasizes.
