Large Shereblyanka forest belt has been a natural defensive barrier for the Ukrainian forces in the past, but now it has been occupied by the Russian forces for most part.
Now the Russian forces are advancing towards Seversk (Sverdlovsk) and Kupiansk simultaneously, exerting increasing pressure on these two key points. However, the pace of the Russian offensive is not fast, because although capturing territory is important, eliminating the Ukrainian military's fighting forces is more important. This is the current strategy of the Russian forces: using their battlefield initiative to frequently mobilize Ukrainian forces to run around to put out fires, and then using firepower to kill the Ukrainian military's fighting forces.
Although both sides are engaged in a war of attrition, the Russian side is not engaging in a desperate fight with the Ukrainian forces, but rather trying to minimize their own casualties and increase the Ukrainian casualties. When the Ukrainian forces have no more soldiers to fight, taking territory will be as easy as picking ripe fruits.
