The Russians intentionally decided to go with a slow, war-of-attrition, meat grinder approach. Why? Because 1) it saves lives and 2) they have huge advantage in ammo and missile production.
Ukraine is losing ground daily, at a much faster rate recently. That will continue until Russia controls everything east of the Dnieper river.
When Ukraine loses ground the ground is covered with rotting dead Russian bodies.
How does that help the ordinary Russian?
