Drones, small and large, are the biggest change in warfare in decades.
I imagine this will become bigger news at some point.
Indeed. Yesterday I watched a compilation of drone footage from the Armenia v Azerbaijan war. The capabilites of drones have rendered armoured vehicles useless, and trenches no longer offer any protection to soldiers. It was pretty horrific to watch.
So systems that make the use of drones unfeasible in a certain pre-defined area, e.g. by interfering with communication, should become a hit, too. If that's technologically possible.
