Following on to this, I would not be remotely surprised if drones continue to be a threat to see something like a man portable gepard hooked up to an EW system, as given the speed those things move and how hard even hitting regular old Canadian Geese or errant clays under non-combat situations, I don't know how you would economically fight drone swarms short of a mini Phalanx CIWS or something.
Maybe ironically, I wonder if we won't see things like the Bofors 40mm guns continue to be prolific if they get successfully retasked to fighting drones (and they would end up like the M2, fighting long after it was initially conceived).
For the smaller drones it's an even more rapidly evolving, high-tech arms race. AFAIU, over the past year most of the battlefield drones have switched to kilometers-long fiber optic tethers to avoid electronic jamming. I dunno what all the defensive measures are, but one is using other drones to cut the cable. I think they may also be using directed energy weapons, now, though not sure how widespread that is.
Current method from public posts seems to be run on GPS and remote data link until jamming bubble is hit, then transition to visual/thermal/radar recognition of target for terminal approach.
Jamming only covers a small area (yes, some areas will have overlap), or a narrow movable cone. Both systems can be overran by the above method, or by swarms overriding directional electronic attack
EOS (Aust) sent 160 of these to Ukraine to be mounted on M113 carriers and Kozak MRAPs. Could also be put on the back of a Toyota Hilux or other technicals.
They use a Bushmaster 30mm cannon with proximity fuse HE rounds so they don't need to hit the drone dead on.
