Ukraine forces disrupt Russian operations

 ISW:

New reports confirmed that Ukrainian forces conducted a successful limited counterattack near the Kherson-Mykolaiv oblast border on May 28, forcing Russian forces onto the defensive. This Ukrainian counterattack is likely intended to disrupt Russian efforts to establish strong defensive positions along the Southern Axis. While the Ukrainian counterattack does not appear likely to retake substantial territory in the near term, it will likely disrupt Russian operations and potentially force Russia to deploy reinforcements to the Kherson region, which is predominantly held by sub-standard units. Ukrainian counterattacks may additionally slow Russian efforts to consolidate administrative control of occupied southern Ukraine.[1]

Russian forces continued to assault Severodonetsk on May 29 but did not make any confirmed advances; Russian progress in intense urban combat will likely be slow. The Russian campaign in eastern Ukraine—which previously aimed to capture the entirety of Luhansk and Donetsk Oblasts—is now focused almost entirely on Severodonetsk. Russian troops are unlikely to be able to conduct multiple simultaneous operations and will likely further deprioritize advances southeast of Izyum and west of Lyman in favor of concentrating available forces on Severodonetsk in the coming days.

The Russian operations continue to be modest compared to their original objectives.  The operations against Ukraine have exposed Russian conventional weapon systems as lackluster and inadequate.  They have lately relied mainly on standoff weapons like artillery while they scrounge for troops including the elderly.
