The modern battlefield in Ukraine has seen a multi-year proliferation of low-cost, first-person-view (FPV) drones that cost around $500 per unit and are modified to deliver small explosive payloads.

These measures have achieved partial success, yet the move by both sides to deploy non-jammable fiber-optic drones has rendered these electronic jammers useless.
