It depends on how common guys like this are. Literally mind bending maneuverability is possible with quadcopters... For a price; It comes down to how much you want to spend killing one soldier though. I've been reading some things about the Ukrainian ones, and I get it now.

Their mindset is more focused on price performers, detonating more than 100 commercial off-the-shelf drones daily, without even bothering to harden them against EW. This has hampered their range significantly, but they don't mind. Under normal circumstances a quadcopter can range a few km, but in this warzone it's closer to 500m.

Pilots like the one above are rare enough that you need a great reason to put them in a warzone. Quadcopters like the ones he uses aren't cheap, either. I think Ukraine is doing incredible work and approaching their task correctly, on review. I come at this from a hobbyist perspective, which sees higher skill levels but is currently a lot less practical in warfare terms.
