Fiber-optic drones have changed the nature of warfare — but they are leaving behind a problem that has received very little attention so far. When a drone explodes, the thin cable does not disappear. It settles in fields, forests, and soil — and remains there indefinitely.

Ukraine and russia are together using at least 100,000 such drones every month. A single drone’s spool can carry up to 10 kilometers of cable or more. The scale of this contamination is already difficult to comprehend, and it continues to grow.

For humanitarian demining teams, this creates fundamentally new risks. Millions of kilometers of nearly invisible cable scattered throughout the combat zone make movement more difficult, become entangled in equipment, and can conceal genuine hazards. Humanitarian demining is already a task that will take decades. Fiber-optic cables make the work even more difficult — and there is currently no methodology for dealing with them at all.

Experts insist that the first step is to officially recognize fiber-optic cable as a separate form of war-related contamination. Without such recognition, there will be no standards, resources, or technological solutions. How exactly this invisible layer should be removed from fields and forests remains unknown.

And the drones keep flying.
