Just a note: The US company Skydio makes a pretty good autonomous drone. I have one that can fly though or over the woods on its own if you give it keyframe points to navigate to/from. It can also spot things (e.g., people, cars, etc.) That Skydio recently got a military contract should be no surprise, given that the most popular drones (e.g.DJI Mavic) are manufactured and exported under CCP control.
