You don't reveal too much of your hand if you are at all serious and as you say they appear to be testing response at the moment.
If they are twonks I think they would have decamped once they realised there was high velocity accurate anytime sighted kit around with the right guys on the other end.
I think if you were serious you would have developed your own secure communication system for the drone to be honest and I think this is why they haven't caught one or it's operative as yet. It would be naïve in the extreme to use standard kit in this sort of scenario. These boys and girls possibly have access to Saudi funding so money is no object for research and development.
If it turns out to be a standard unit operated by PS4 kids they will have made the whole of our security forces look pretty damn silly.
