This doctrine is changing fast in that conflict. Any enemy structure sticking out is a prime target for drones, and there around 10,000 drones used daily and this number keeps rising continuously, often one-way FPV kamikaze drones. Anything that sticks out is bombarded into oblivion, the tactic now is more akin to hiding or blending with surroundings.

Once they figure out cheap way for semi-autonomous swarms (as in 1 guy piloting say 50 drones, mix of bombers, kamikadze ones and possibly ones carrying some AA rockets) skies will be full of little deadly plastic birds and fortified positions on the battle line will be fully thing of the past.

Always great to see someone who has probably never served pontificating on military affairs with such an air of authority.

Sort of like listening to a lawyer hold court on the future of software development.
