Saw that movie scene. One of the most frightening prospects I’ve ever seen. The drones are probably way too small and stealthy to be detected. Too numerous and fast to be shot down. Extremely portable and easy to conceal. Incredibly accurate and deadly against personnel.
If the scene in the movie is a potential reality, I just have to wonder what kind of countermeasures are possible in a practical way? Jamming? I suppose these could be autonomous and not relying on any signal for guidance once programmed and launched. An EMP based shield (not jamming signal but destroying on-board electronics)?
Israeli companies already have anti-drone swarm technology. AI controlled relatively small lasers, small enough to be mounted on a small plane.
Russian Saiga-12 shotgun (modeled after the AK series).
Ideally, you would need something that could fill the air above you with flak. Maybe some upward-pointed claymores.
Great movie...but scary method of battle.
Still, I’d like to have a few...LOL.
