If these would be as successful as implied, we’d have seen lots and lots of videos of them in operation, from both sides.

Sure, these might work in some small operations but nothing changes the fact that these are far too easily disabled by small arms fire, cheap drones, even anti-personnel mines etc. Now if they’d have their own air defence (small radar/camera array + shotgun), be faster and more agile and someone would be able to solve the control issues under jamming (with God forbid something else than AI), then maybe, maybe these would make a difference in the frontline too.

But until then, only useful outside the drone threat in the rear, or in some diversion missions.
