There was a video of a soldier wading through massive amounts of fiber near the front line. Just imagine that for each drone attack there will be 10-50km of fiber dropped on the landscape. It will not rot and stay there until someone cleans it up.
Early on: Drones in war!
Then: Ahh EW makes them useless!
Then: Fiber optics defeat EW!
Then: But you can follow the cable!
Then: But you can try to respool the cable with a power drill!
Every week it seems is a new move.
Next Next up: Decoys.
The fiber-optic drones have small warheads/payloads. They are used to hunt the enemy's EW transmitters. Once the jammers have been suppressed, then the radio-controlled drones with bigger payloads go to work and do the bulk of the damage.
