Perhaps, the real counter is just electronic warfare and early warning systems, drones are just another tool in the toolbox.
Since if you have let's say a tunnel, this tunnel will have a entrance just collapsing the entrance will just fuck the entire thing up. plus you can fly a small one inside of the tunnel, at which point the you're fucked you shoot it has a 50/50 chance at going boom and collapsing the tunnel with you inside, but if its high up in the sky from a few km's away and you shoot it. now i am sure they'll use some for stealth purposes, but i doubt it'd be the entirety.
