Remember, Russia is primarily relying on glide bombs to put artillery pressure on the front because Ukraine has so effectively denied Russia the ability to move its artillery into forward threatening positions.
Ukraine's use of drones here thus could collapse the Russian war machine if Ukraine gets good enough at this.
I have made this point before but this is precisely why helicopters that can mount radars are more relevant than ever and more survivable than fixed wing aircraft, they aren't tied to massive static airbases and infrastructure.
