Futurology

There are working on the next generation.

Probably an automated swarm tightly connected in a mesh network with either charging station they can fly to or mounted solar panels. Most will stay dormant, when one of the patrol drones spots an enemy, it will send a couple of the smaller kill drones to its location.

I'm guessing we might see some new camo roll out with a QR like codes embedded in them. That or maybe they will constantly blink ir lights using a code they change every week or so.
