From what I've seen and read, the thing preventing you being traced by someone following the fibre is simply huge numbers of drones literally flying into enemy soldiers and detonating. It is terrifying viewing the videos as people try and (unsuccessfully) dodge the drones, or are accidentally shot by their own comrades who are trying to (unsuccessfully) shoot down the drone, or are run-over by their own side's tanks/APCs who are panicking and trying to (unsuccessfully) outrun a drone, or are blown up trying to (unsuccessfully) take cover in a trench/dugout/building/APC/tank and a drone literally just flies in through the door/window/hatch and detonates (perhaps followed by another two or three for good measure) Genuinely sounds absolutely terrifying, more so than any other horror stories of e.g. WW1 & 2.
