The Line of Contact is becoming too lethal for soldiers and crewed weapons. In Ukraine, drones account for the majority of russian casualties. The "grey zone" between opposing dug-in positions has greatly widened beyond rifle range. Drones are now out-ranging the Soviet era artillery that russia uses.
So it is simply too dangerous for a sniper to crawl across 20-30 Km of grey zone under enemy observation day and night to reach an advantageous sniper's nest.
