Russian forces are pursuing at least three operational-level efforts that are not mutually reinforcing but let Russian forces prioritize grinding, tactical gains on a single sector of their choice at a time. Ukrainian forces will increasingly struggle to defend against these Russian efforts the longer Ukraine lacks further US military assistance. Ukrainian Commander-in-Chief Colonel General Oleksandr Syrskyi stated on April 13 that the situation in eastern Ukraine has significantly worsened in recent days and that Russian forces are conducting mechanized attacks in the Lyman, Bakhmut, and Pokrovsk (west of Avdiivka) directions. Syrskyi stated that hot and dry weather conditions have made most open terrain accessible to Russian tanks and that Russian forces are dedicating new units to achieving tactical successes despite heavy losses. The Russian efforts in the Lyman, Chasiv Yar, and Pokrovsk directions each pursue operationally significant objectives, but these operations are not mutually supporting, and Russian forces still seem to be alternating emphasis among the different operational directions rather than leaning into all three at any given time. Ukrainian forces have successfully defended against prior Russian operational-level offensive efforts of this sort when they had the resources the US is currently withholding, forcing these efforts to culminate before they could achieve operationally significant results. Ukrainian forces currently struggle with significant shortages of both artillery shells and air defense means, both of which are critical components of their defense, and Russian forces are capitalizing on these shortages and improved weather conditions.
The Russian military command likely assesses that Ukrainian forces will be unable to defend against current and future Russian offensive operations due to delays in or the permanent end of US military assistance. Russian forces have recently periodically shifted their focus among offensive operations in the Lyman, Chasiv Yar, and Pokrovsk directions; Russian forces first prioritized the capture of Avdiivka in early 2024, alongside simultaneous but less intense operations along the Kupyansk-Svatove-Kreminna line, then leaned into the Lyman direction while slightly decreasing the tempo near Avdiivka, and now are intensifying efforts to seize Chasiv Yar in March-April 2024. Though Russian forces likely lack the ability to conduct more than one simultaneous effective large-scale operational effort as they have throughout the war, Russian forces are now able to use multiple alternating offensive efforts to stretch Ukrainian defensive capabilities amid Ukrainian artillery and air defense shortages. The current pattern of Russian offensive operations allows elements of units participating in less intensive efforts to rest and reconstitute while other units, presumably those that are more rested or those that have recently received reinforcements. They can then intensify efforts in another operational direction, forcing Ukrainian forces to reallocate their defensive resources across the theater and creating vulnerabilities that Russian forces can exploit. Russian forces are reportedly developing operational- and strategic-level reserves capable of sustaining ongoing offensive operations in Ukraine, likely to support an anticipated spring-summer offensive effort. ISW continues to assess that these reserves are unlikely to be ready to act as a first-echelon penetration force or second-echelon exploitation force capable of conducting large-scale mechanized assaults in 2024 as long as Ukrainian forces have the wherewithal to resist them. Russian forces would more likely use these reserves to restaff or reinforce existing formations and continue grinding, infantry-led assaults with occasional limited mechanized pushes in their direction of choice at key moments. If the United States does not resume providing aid to Ukraine and Ukrainian forces continue to lack essential artillery and air defense munitions in particular, however, even badly-trained and poorly-equipped Russian troops might be able to conduct successful offensive operations.
Key Takeaways:
- Russian forces are pursuing at least three operational-level efforts that are not mutually reinforcing but let Russian forces prioritize grinding, tactical gains on a single sector of their choice at a time. Ukrainian forces will increasingly struggle to defend against these Russian efforts the longer Ukraine lacks further US military assistance.
- The Russian military command likely assesses that Ukrainian forces will be unable to defend against current and future Russian offensive operations due to delays in or the permanent end of US military assistance.
- The offensive effort to seize Chasiv Yar offers Russian forces the most immediate prospects for operationally significant advances as the seizure of the town would likely allow Russian forces to launch subsequent offensive operations against the cities that form in effect a significant Ukrainian defensive belt in Donetsk Oblast.
- Russian threats to Druzhkivka and Kostyantynivka are very operationally significant since these “fortress” cities help form the backbone of the Ukrainian defense in Donetsk Oblast and of eastern Ukraine in general.
- Russian forces may not be able to seize Chasiv Yar rapidly and would likely struggle to leverage its operational significance immediately as long as Ukrainian forces have the resources needed to hold their positions.
- Ukrainian artillery and air defense shortages resulting from the lack of US security assistance are allowing Russian mechanized forces to make marginal tactical advances, and future Russian mechanized assaults may be able to achieve more significant gains should the US continue to withhold assistance to Ukraine.
- Germany announced that it will immediately transfer another Patriot air defense system to Ukraine in response to recent very urgent Ukrainian requests for additional Patriot systems to defend against the increased Russian strike campaign and ongoing Ukrainian efforts to expand Ukraine’s air defense capabilities.
- Russian forces made confirmed advances near Chasiv Yar (west of Bakhmut) and Donetsk City.
- Bloomberg reported on April 12 that Russia still relies on Chinese companies to supply most of the foreign-produced machine tool components and microelectronics to Russia’s defense industry for Russian weapons production.
