Yeah, that is exactly what I mean. Look it up on YouTube, plenty of examples.
Well yes and no. Military drones are not any more autonomous then the off the shelf ones, and I am really not sure where you got that idea. They are piloted like any other aircraft, except the pilot sits on the ground, not in the air.
As far as taking those down with birds, military UAVs (They don't call them drones) come in pretty much every size, from this:

Clearly no bird of prey is going to handle the last two unless it one of those Eagles from LOTR. But all four are completely piloted, none of them are autonomous in any way. Yes, if the connection to ground is broken they can return and land (crash) on their own, but none of those fly on their own. I have worked with all four of those, and I have flown the first two personally.

Gorgon Stare is a sensor system, not a drone. It can be mounted on a range of drones, or on conventional aircraft, or on Aerostats. I have worked with several sensor packages, but I can't really discuss which ones or what they do. It is also worth noting I was a tactical commander, not a sensors guy, so I got intel from them and signed for the property, I didn't directly operate the bigger stuff. I did play with the smaller stuff, but it was literally just that, playing around with it, I had soldiers that did it full time.
