Institute for the Study of War: Delay in western supplies opens the way for Russian advances

Ukrainian forces will likely be able to establish new defensive lines not far beyond Avdiivka, which will likely prompt the culmination of the Russian offensive in this area. The Russian Ministry of Defense (MoD) claimed on February 18 that elements of the Russian Central Grouping of Forces completely captured Avdiivka, advancing 8.6 kilometers in depth in the area, and that Russian forces continue offensive operations to capture additional territory in Donetsk Oblast. Several Russian milbloggers claimed on February 18 that Ukrainian forces lack well prepared defensive positions west of Avdiivka and that Russian forces will be able to advance further into western Donetsk Oblast behind “panicked” and “disorganized” Ukrainian forces withdrawing from Avdiivka. ISW has still not observed footage of disorderly Ukrainian withdrawals to support these Russian claims and would expect to observe such footage if the withdrawal was disorderly on a large scale given the normal patterns of Russian sources with access to such material. One Russian milblogger claimed that a large-scale collapse of the Avdiivka front is “unlikely” as Ukrainian forces withdraw to prepared defensive lines, however, indicating that the Russian understanding (or presentation) of Ukrainian defensive capabilities on this sector of the front differs from source to source.

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. 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.

Delays in Western security assistance to Ukraine are likely helping Russia launch opportunistic offensive operations along several sectors of the frontline in order to place pressure on Ukrainian forces along multiple axes. Russian forces are currently conducting at least three offensive efforts—along the Kharkiv-Luhansk Oblast border, particularly in the directions of Kupyansk and Lyman; in and around Avdiivka; and near Robotyne in western Zaporizhia Oblast. After the withdrawal of Ukrainian forces from Avdiivka and the subsequent Russian claim of control over the entirety of Avdiivka, ISW and several Ukrainian and Western sources assessed that delays in Western security assistance, namely artillery ammunition and critical air defense systems, inhibited Ukrainian troops from defending against Russian advances in Avdiivka. Critical Ukrainian shortages in Western-provided equipment and fears of the complete the cessation of US military aid have forced Ukrainian troops to husband materiel along the entire front, which has likely encouraged Russian forces to exploit the situation and launch limited offensive operations outside of the Avdiivka area, which they have done along the Kharkiv-Luhansk Oblast border area since early January 2024 and in western Zaporizhia Oblast over the past 48 hours. These Russian offensive efforts will likely hinder Ukrainian forces from preparing personnel and materiel for renewed counteroffensive operations, emphasizing the operational disadvantages that Ukraine will suffer if it simply digs in and attempts to defend for the rest of 2024 as some Western states and analysts advocate.

Key Takeaways:



  • Ukrainian forces will likely be able to establish new defensive lines not far beyond Avdiivka, which will likely prompt the culmination of the Russian offensive in this area.
  • Delays in Western security assistance to Ukraine are likely helping Russia launch opportunistic offensive operations along several sectors of the frontline in order to place pressure on Ukrainian forces along multiple axes.
  • Russian forces are likely seeking to take advantage of two windows of opportunity with the recent initiation of their simultaneous offensive operations—the period before the upcoming spring thaw and the nuanced dynamics of Western aid provision.
  • The Russian capture of Avdiivka after four months of intensified offensive operations exemplifies the way that Russian forces pursue offensive operations that do not necessarily set conditions for wider operational gains but still force Ukraine to commit manpower and materiel to defensive operations.
  • 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 taken as demonstrating this capability.
  • Ukrainian officials are investigating two instances of apparent Russian violations of the Geneva Convention on prisoners of war (POWs) in occupied Donetsk Oblast.
  • Russian milbloggers criticized the Russian Ministry of Defense (MoD) for failing to recognize 1st Donetsk People’s Republic Army Corps (DNR AC) Commander Lieutenant General Sergei Milchakov and the “Veterany” Assault Brigade (Volunteer Corps) for aiding in the Russian capture of Avdiivka, highlighting continued tension between Russian regular and irregular forces.
  • The Washington Post reported that the Kremlin has been orchestrating a large-scale effort to spread disinformation in the Ukrainian media since January 2023, corroborating recent Ukrainian official reports about Russian information operations that use fake Telegram channels to infiltrate the Ukrainian information space.
  • Danish Prime Minister Mette Frederiksen announced on February 18 that Denmark is donating its “entire artillery” to Ukraine.
  • The US is reportedly turning to India and China to engage Russia about Russia’s reported intent to launch an unspecified anti-satellite nuclear weapon into space.
  • Russian forces recently made a confirmed advance in western Zaporizhia amid continued positional engagements along the entire line of contact on February 18.
  • Russian occupation officials continue to use educational programs as means of Russifying occupied Ukraine.

Forced displacement represents one of the most pressing humanitarian issues of our time. Individuals and families, torn from the fabric of their communities, find themselves navigating a world of uncertainty, often without basic necessities or a clear path to safety. There are currently some 110 million forced displaced, and this number is growing by 10 million each year!

At the heart of this crisis are the political triggers. Armed conflicts, ethnic or religious persecutions, and systemic human rights abuses force millions to flee their homes in terror. Many are displaced within their own national boundaries, while others seek asylum abroad. If these factors change as a result of political shifts at home or the pressures from abroad, they can return to their homes. Forced displacement is thus different from environmentally driven displacement, as victims of climate change may never be able to return to their homes.

The ramifications of any sort of displacement are profound, not just for those directly affected, but also for host communities and countries. Overburdened infrastructures, socio-economic strains, and cultural tensions can arise, necessitating comprehensive strategies to foster harmony and integration. Yet the root causes of forced displacement can be remedied with a concerted focus by local players and international diplomacy.

Organizations like Refugees International play a crucial role in this arena, advocating for the rights and needs of the displaced, conducting on-the-ground assessments, and influencing policymakers to take informed actions. Their relentless work underscores the gravity of the situation and the urgency ofinternational cooperation. But they, too, are overwhelmed by the rapid expansion of the crisis.

International Humanitarian Law (IHL), with its core principles centered on the protection of civilians during conflicts, plays a pivotal role in this discourse. Yet, despite clear legal frameworks, compliance remains
inconsistent. This initiative emphasizes the importance of upholding and reinforcing these international standards.

It’s not just about recognizing the problem; it’s about active engagement. We urge governments, organizations, and individuals to prioritize the rights and needs of the forced displaced. Through collective efforts, informed policies, and sustained advocacy, we can shift the narrative from passive acknowledgment to proactive intervention.
