If I’ve learned anything from watching combat footage from Ukraine, it’s that shotguns are very effective at taking down drones. Who would’ve guessed the thing used to kill birds kills drones?
Sure a buckshot works great against a drone or two, but what do you do when there's a swarm of them? We're getting to that level of sophistication with them pretty quickly.
You either need more guns or more range, I guess. Swarming the other guy first is also an option, or sending drones after the drones, although you lose any cost advantage that way.
I know the is NCD, but it sounds like the professional military thinkers are expecting things to keep shifting towards emphasis on mobility and concealment, just because the post-identification kill chain is getting so foolproof.
