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.

great points
