A Ukrainian soldier's video showed the optical fibers left by a suicide drone in the field, and it could be seen that there were fine lines everywhere. A lot of optical fibers were entangled around the feet of one of his comrades-in-arms, but they didn't bother to clean them up because even if they removed them, new ones would quickly wrap around again. The Russian military first used optical fiber suicide drones in the Kursk region last autumn, and after that, these suicide drones began to spread. The Ukrainian army also used optical fiber suicide drones, but the number was far less than that of the Russian side. Western media speculated that the Russian military currently uses about 1,000 optical fiber suicide drones on the front line every day, and due to increased production capacity, the usage will soon increase to 2,000.
The advantage of optical fiber suicide drones is that they are immune to any electronic warfare facilities suppression, and they can maintain stable signal transmission in densely built-up areas and forest regions as well.
