Drones don't remove people from the battlefield, they further the trend of there being no boundary to "the battlefield", putting everyone on it.
They can, depending on how they are employed, reduce the casualties (total and particularly civilian) on both sides of a conflict for any degree of military impact (Ukraine's recent strike against Russian bombers is an example), or they can increase the civilian death toll for marginal military impact (the accounts of Israeli gun- and missile-armed drones directly targeting civilians in Gaza being an example of what that could look like.)
Note for example, that Ukraine attack, although it caused no civilian casualties... it relied heavily on civilian infrastructure. Ukraine rented warehouses, common trucks, and hid the drones in normal shipping containers.
Thus indeed, this made the battlefield larger instead, now common trucks, warehouses and shipping containers are legitimate targets.
What Ukraine destroyed doesn't help either, for example they destroyed early warning airplanes intended to warn Russia if incoming missiles are nuclear or not. How Russia have to assume incoming missiles are nuclear, specially if they are flying in the regions where their land nuke detectors were destroyed too (I think 1 or 2 years ago Ukraine did that).
Thus Ukraine proved, that civilian equipment can destroy nuclear deterrence. Now common trucks and containers are a threat as big as many advanced military hardware out there. A truck with a bunch of drones can open a hole in your nuclear defense as much as stealth planes were needed for this before.

yes, that is the point i've been making for a while - those cheap automated systems, the drones being the first examples of it, is the new MAD/equalizer weapons now available to all countries, not only to the large nuclear ones (and that becomes very important for avoiding future wars giving for example growing doubt that NATO, and USA in particular, would come to the defense of Baltic countries, whereis several millions of drones (including larger long range ones) which Baltic countries can get relatively easy for several billions of dollars may pose an unacceptable high cost to Russia of any potential aggression against those countries).
In this particular case a much smaller Ukraine can use that MAD/equalizer potential to win the war, or at least to get a great negotiating position by systematically severely degrading Russia's strategic capabilities toward making Russia potentially defenseless against US or China, or even say Turkey.
That is how i think they can degrade strategic air/missile defense systems https://news.ycombinator.com/item?id=42529638
And imagine if similarly to the plane attack Ukraine would attack Russian nuclear submarines parked openly at the bases (say using ships for drone launching instead of trucks) - there is no risk of destruction of those submarines, yet 10-50kg drone can damage the skin and outer hull forcing the submarine out of service for prolonged time.
