When people imagine AI soldiers, they think of better versions of human soldiers and human controlled vehicles

I think a great weapon for AI would be a noise weapon. Basically any volume from disabling pain to exploding human heads frequencies, but has no effect on AI who just turn their microphones off so they aren't bothered by the screaming.

Noise goes around corners and penetrates obstacles and armor. They could probably also do a lot with gases that our weak little oxygen dependent lungs and sensitive skin couldn't handle.

As we know from Shang-chi and the Legend of the Ten Rings, the proper audio injection for maximal confusion is to suddenly sing Hotel California very loudly. ☺️
