Russia realized that it would be fighting, equipment-wise, against the entire West, so it engaged in a war of attrition.

"Attritional wars require their own ‘Art of War’ and are fought with a ‘force-centric’ approach, unlike wars of manoeuvre which are ‘terrain-focused’. They are rooted in massive industrial capacity to enable the replacement of losses, geographical depth to absorb a series of

defeats, and technological conditions that prevent rapid ground movement. In attritional wars, military operations are shaped by a state’s ability to replace losses and generate new formations, not tactical and operational manoeuvres. The side that accepts the attritional

nature of war and focuses on destroying enemy forces rather than gaining terrain is most likely to win."

This explains Russia's "slow" progress in winning against the cuckrainians.

There are currently more daily losses in the Ukrainian army than newly mobilized men joining it.

To surrender to the Russian forces is seen as a real opportunity, and entire brigades are taking it.

Once they surrender, they are not asking to be put on prisoner exchange lists, as they'll just be sent back to the front to die.
