Ukraine’s drone technology

This was on CBS’ 60 Minutes tonight, and pretty fascinating.  War tactics are being turned upside-down right now with drone technologies (I saw a related report yesterday that those delta-shaped Shahad drones that Iran is raining down so effectively in the Middle East are made of styrofoam and are powered by a motorcycle engine).  
Zelenskyy’s chief drone leader/engineer was interviewed, and they currently have a kill ratio of 1 russian/$1,000; some pretty gruesome kill footage, just one small drone flying right up to a combatant and exploding.  Also some clever machine-gun-armed wheeled robots that are holding off the russians, amphibious drones sinking large ships with an incredible cost/benefit ratio, grenade-launching robots, and even medevac units.  
I had noted 6, 7 years ago that the Hill AFB taxiways/runways run the perimeter of parts of the base, and it would be quite easy to attach a 1”-dia titanium bolt to a drone and then just fly up to the air intake of a ~$120M F-35 and ruin some peoples’ day; sobering stuff.
