What are the system requirements of autonomous military UAV?

It's not that surprising of an accomplishment if you have it target everyone. Gross location movement is available using stuff like GPS and is commonly found in higher end commercial drones. Fine movement for just track and kill movement is not hard with object detection functionality common in security cameras and stuff. You could install any weapon on a drone of suffience size. Technically, I would assume the most powerful that could be fitted to almost any size drone to be biological agents that could be spread over crowds.

Try to keep it simple.

1. Use something like ArduPilot: https://ardupilot.org/

2. Fly to target latitude/longitude of flight line. https://maps.app.goo.gl/6Zy9asA8QcQ9MoGw9

3. Instruct ArduPilot to fly northeast.

4. Run an object detection Python script trained on JPEGs of Russian heavy bomber aircraft. If no objects detected after 2.21 miles, turn around and fly southwest for 2.21 miles and repeat step 4. https://opencv.org/

5. Fly to object.

6. Detonate on or before impact. I'd probably use a couple cheap ultrasonic sensors here.

Notes:

- You can have some slop because you have a lot of these drones and everyone in the Area of Operation is an enemy.

- In reality, instead of measuring distance, you'd have a beginning/end latitude and longitude and fly between those in step 4.
