Drones will rule the battlefield. Until anti drone tech comes up to match it. I was picturing a anti drone system. One system that uses an old school radar anti aircraft gun, also equipped with a set of small missiles like the Iron Dome system, also equipped with some kind of laser weapon, and some kind of electro magnetic EMF weapon. All four in one package, that could engage multiple targets simultaneously. And, this will have to come standard, like SAM systems are now.
Azerbaijan used oil wealth to buy attack drones from Turkey and Israel. It was a huge advantage.
