Russians continue to struggle in Eastern Ukraine

 ISW:

Russian forces made marginal gains on the outskirts of Severodonetsk on June 18 but have largely stalled along other axes of advance. Russian troops are likely facing mounting losses and troop and equipment degradation that will complicate attempts to renew offensive operations on other critical locations as the slow battle for Severodonetsk continues. As ISW previously assessed, Russian forces will likely be able to seize Severodonetsk in the coming weeks, but at the cost of concentrating most of their available forces in this small area. Other Russian operations in eastern Ukraine—such as efforts to capture Slovyansk and advance east of Bakhmut—have made little progress in the past two weeks. Russian forces are continuing to fight to push Ukrainian troops away from occupied frontiers north of Kharkiv City and along the Southern Axis, but have not made significant gains in doing so, thus leaving them vulnerable to Ukrainian counteroffensive and partisan pressure.

The Russian military continues to face challenges with the morale and discipline of its troops in Ukraine. The Ukrainian Main Intelligence Directorate released what it reported were intercepted phone calls on June 17 and 18 in which Russian soldiers complained about frontline conditions, poor equipment, and overall lack of personnel.[1] One soldier claimed that units have been largely drained of personnel and that certain battalion tactical groups (BTGs) have only 10 to 15 troops remaining in service.[2]

This war already doe snot appear worth it to most Russian troops and it persists mainly because of Putin's inability to accept that it was a mistake, to begin with.  The Russian leadership appears unable to persuade Putin to accept reality at this point.
