As the Russia-Ukraine war enters its fifth year in late May 2026, the battlefield presents a complex picture of grinding attrition rather than decisive victory for either side. While Russia continues to occupy approximately 20% of Ukraine and maintains pressure in certain sectors, its offensive momentum has significantly slowed this year. Recent data indicates net territorial losses for Russian forces in April and into May 2026, accompanied by extraordinarily high casualties.
Territorial Dynamics: Slow Advances and Ukrainian Counter-Pressure
Russia made incremental gains throughout much of 2024 and 2025, particularly in Donbas around areas like Pokrovsk. However, the pace has dropped sharply in 2026. According to the Institute for the Study of War (ISW), Russian forces averaged only about 2.9 square kilometers of gains per day in the first months of the year, a steep decline from previous periods.
In a notable reversal, April 2026 marked the first month since Ukraine’s 2024 Kursk incursion in which Russia suffered a net loss of controlled territory — approximately 116 square kilometers. This trend continued into mid-May, with reports of further net losses ranging from 45 to 69 square miles (roughly 116–179 square kilometers) over multi-week periods.
Ukrainian forces have conducted successful counterattacks, particularly in southern sectors such as the Zaporizhzhia and Dnipropetrovsk border areas around Hulyaipole and Oleksandrivka. These operations have reclaimed hundreds of square kilometers since early 2026, aided by improved drone strikes, disruptions to Russian logistics (including Starlink limitations for Russian forces), and fortified defenses.
Russian efforts remain focused on Donbas, using small-unit infiltration tactics, glide bombs, and artillery. Gains, however, are minimal and come at disproportionate cost, with no major breakthroughs toward fully seizing Donetsk Oblast or other strategic objectives.
Manpower Crisis: High Costs on Both Sides
Russian casualties remain the most striking feature of the current phase. Estimates place monthly losses at 30,000–40,000 (killed and wounded) in recent periods. Ukrainian sources claim over 1.35 million total Russian personnel losses by late May 2026. Independent Western assessments, including from CSIS, put total Russian casualties since 2022 at around 1.2 million by early 2026, with hundreds of thousands killed.
Russia sustains its forces through high financial bonuses, regional recruitment quotas, and increased reliance on convicts, foreigners, and less-trained personnel. Reports suggest recruitment has struggled to keep pace with losses in 2026, raising long-term sustainability concerns without full-scale mobilization.
Ukraine also faces severe manpower shortages, mobilization challenges, and war fatigue. Both armies are locked in a war of endurance where innovation — especially in drones and long-range strikes — plays a critical role.
Broader Strategic Context
This is not the fluid war of 2022. Russia has adapted by shifting to massed artillery, drones, and missile strikes on Ukrainian infrastructure and energy systems. Ukraine, in turn, has enhanced its defensive capabilities and conducted deep strikes on Russian rear areas, oil facilities, and logistics.
Despite battlefield friction, Russia shows no signs of imminent collapse. It retains the initiative in some areas and benefits from greater overall mass. However, exaggerated Kremlin claims of inevitable victory contrast with the reality of stalled offensives and rising costs. Ukraine’s ability to impose net losses demonstrates resilience and tactical adaptation, particularly when supported by Western aid.
The Bottom Line: The war remains a protracted, high-cost stalemate. Putin is not rapidly losing vast territories or “running out of troops” in a catastrophic sense, but 2026 has exposed vulnerabilities in Russia’s offensive capabilities. Success will ultimately depend on which side better manages resources, manpower, technology, and international support in the months ahead. Claims of total dominance by either side overlook the grim, attritional nature of this conflict.
