Interesting comments from the ISW today
1) Available imagery, which ISW will not present or describe in greater detail at this time to preserve Ukrainian operational security, does not support claims that Ukrainian forces lack prepared defensive positions west of Avdiivka. The Ukrainian command also recently committed fresh units to the Avdiivka front to counterattack advancing Russian forces and provide an evacuation corridor for Ukrainian units withdrawing from Avdiivka.[4] These newly committed units are likely able to establish and hold defensive positions against Russian forces, degraded by their assaults on the town, west of Avdiivka. Russian forces, which have suffered high personnel and equipment losses in seizing Avdiivka, will likely culminate when they come up against relatively fresher Ukrainian units manning prepared defensive positions.
2) Russian forces have not yet demonstrated an ability to secure operationally significant gains or conduct rapid mechanized maneuver across large swaths of territory, and the capture of Avdiivka should not be taken as demonstrating this capability. ISW distinguishes between tactical gains, relevant at the tactical level of war in the near vicinity of the fighting, and operational gains which are significant at the operational level of war and affect large sectors of the entire front line.
