it's artillery, it's drones as you say, it's air force, it's mines, it's trenches, but the big one is ISR 4k livestreaming the entire front you can't mass soldiers easily without it being seen by the other side. which makes its pretty hard to move in general.
>oh the enemy is massing 5k troops near kuptyanovksosivanishodessa, time to strike them with missiles, artillery, drones, airforce and dump a bunch of landmines near the frontline. also move some troops and armor there to match it.
and suddenly you can't move anymore.
