In northern Ukraine, it was boy vs. Russian drone. The boy won.

It’s a really horrible problem the Russians are imposing on Ukrainian civilians in these towns where they’re using the human safari tactic,” said Robert Tollast, a military sciences researcher at the Royal United Services Institute in London....Adapting an off-the-shelf FPV drone to fiber-optic controls is a cheap and effective hack, Tollast said. Although the filament can tangle or break as it’s draped across miles of countryside, units often deploy two or three drones on each mission to provide backup and better targeting reconnaissance. The advantages of the physical connection are huge, Tollast said, and both armies increasingly use them for a range of battlefield missions. Not only are they immune to jamming, they don’t lose signal at longer distances or behind barriers the way line-of-sight radio controls do."
