Brit soldiers tune radio waves to fry drone swarms for pennies

Layered defense. AND is better than XOR in this case.

The Ukrainian soldiers with shotguns can be overrun by an swarm and a shotgun’s effective distance isn’t great compared to how high drones fly for scouting. Better to have a truck mounted heavy weapon behind you and shotguns covering grunts on the front line working together.

That said, the front line of the RU/UA war is not the only useful place for this weapon. Presidential rallies, augmentation of the Iron Dome, defense of civilian airports, etc are all good candidates for a large truck-mounted weapon to counter swarms of drones.

Netting spread across tall poles are about the only thing that is not outright illegal. HOA's and some towns will throw a fit about the netting. Using radio weapons outside of a war-zone will likely result in fines if it interferes with anything revenue generating and possibly even arrest.

Yes, but presumably at some cost to drone's performance.
