The reported concentration of the Russian military’s entire combat-capable ground force in Ukraine and ongoing Russian force
generation efforts appear to allow Russian forces to conduct routine operational level rotations in Ukraine. Ukrainian Main Military Intelligence Directorate
(GUR) Deputy Chief Major General Vadym Skibitskyi stated on January 11 that Russian forces have 462,000 personnel in Ukraine and that this represents the entire land component of the Russian military. Skibitskyi stated that most Russian units in Ukraine are
manned at between 92 and 95 percent of their intended end strength and that the size of the Russian grouping in Ukraine allows Russian forces to conduct rotations throughout the theater. Skibitskyi stated that Russian forces withdraw units that are at 50 percent
or less of their intended end strength to rear areas and return them to the front following recovery and replenishment. Russian Security Council Deputy Chairperson Dmitry Medvedev stated on January 11 that the Russian military has successfully replenished
Russian forces in Ukraine through an ongoing crypto-mobilization effort that generated over 500,000 new personnel in 2023.
ISW previously observed routine Russian struggles to conduct operational level rotations from the start
of Russia’s full-scale invasion in February 2022 through Ukraine’s summer 2023 counteroffensive. The apparent Russian ability to generate forces at a rate equal to Russian losses likely provides Russian forces the ability to replenish units that the Russian
command has withdrawn from the line due to degradation and later return these replenished units to the front. Russian forces maintain the initiative throughout eastern Ukraine, and the absence of Ukrainian counteroffensive operations likely removes pressure
on operational deployments that had previously partially restrained the Russians‘ ability to conduct rotations. Russian forces have not seized the battlefield initiative in Kherson Oblast, however, and appear to be degrading units and formations operating
near the Ukrainian bridgehead on the east (left) bank of the Dnipro River without making apparent efforts to conduct operational level rotations (although they do appear to conduct tactical-level rotations). Russian forces have conducted several regroupings
during localized offensive operations in the Avdiivka, Bakhmut, Lyman, and Kupyansk directions since early October 2023, which likely provided Russian forces time to conduct the rotations Skibitskyi described. ISW has not observed widespread Russian complaints
about a lack of rotations throughout the theater since summer 2023, and the overall tempo of Russian operations is consistent with Skibitskyi’s reporting.
- The reported concentration of the Russian military’s entire combat-capable ground force in Ukraine and ongoing
Russian force generation efforts appear to allow Russian forces to conduct routine operational level rotations in Ukraine.
- Russia’s ability to conduct operational level rotations will likely allow Russian forces to maintain the overall
tempo of their localized offensive operations in eastern Ukraine in the near term, but it is unclear if Russian forces will be able to conduct effective rotations in the long term or in the event of intensified Russian offensive efforts or a significant Ukrainian

to fulfill operational requirements in Ukraine and that munitions shortages will continue to prompt Russia to source supplies from abroad.

favorable terrain for mechanized maneuver warfare as the ground freezes in the coming weeks.

- The US Department of Defense (DoD) Office of the Inspector General published a report on January 11 that states
