The drones will soon be autonomous. The technology is already here, just not well distributed. EW (except for EMP pulse) will be a dead end. They are already tracking down signal sources and targeting them. The drones fly around till they get a signal maximum then look down. I have also seen enemy analog video snooping where they watch the drone take-off point and geo-locate it to bomb.
