Here "engagement" means "target was hit". What does "aiming supported by an artificial intelligence system" mean? What does "adjustments from an unmanned aerial vehicle" mean? The rifle has "an effective range of up to 2,000 m, and a maximum range of up to 7,000 m" (though it was apparently effective at 4,000 meters). Does "maximum" vs. "effective" mean you're unlikely to hit anything over 2,000?

This war is Peak Sniper.

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.
