The fifth year of Russia's full-scale war against Ukraine highlights a fundamental reality: Moscow has not lost its ability to launch offensives, but its offensive model is increasingly losing its strategic meaning. The Russian army is still capable of pressing the front line, throwing infantry forward in small groups, erasing tree lines with artillery, deploying guided aerial bombs, saturating the skies with drones, striking the rear with missiles, and maintaining a high tempo of local attacks. However, a massive chasm has formed between tactical advancement and a strategic breakthrough. Russia can capture a few streets, tree lines, villages, or industrial zones, but it is proving less and less capable of turning these captures into a political victory.
This is the central question of the current stage of the war: has the Russian model exhausted itself? The answer cannot be reduced to a simple "yes" or "no." It has not exhausted itself as a machine of violence. It remains dangerous, massive, brutal, and heavily resourced. Yet, it is increasingly exhausting itself as a model for achieving victory. The Russian army can kill, destroy, terrorize, and scorch land, but it finds it harder and harder to alter the overall configuration of the war in its favor. In this sense, the war has not entered a phase of Russian catastrophe, but rather a phase of Russian strategic viscosity: Moscow continues to move forward, but each new meter costs it more than the last, while the political return becomes ever more dubious.
Ukraine, in turn, is by no means in a comfortable position. It faces shortages of manpower, air defense systems, missiles, ammunition, stable external financing, and time. However, the Ukrainian model of warfare has evolved: it is built not merely on defense, but on the technological disruption of the Russian offensive. Drones, intelligence, distributed fire loops, long-range strikes, digital logistics, and unit-level adaptation are turning the front into a space where Russia's numerical superiority no longer guarantees an automatic result.
The Front No Longer Resembles a Conventional Line
The primary transformation of this war is the disappearance of the traditional concept of the front line. It is no longer just a line of trenches, fortified areas, and artillery duels. It is a multi-layered kill zone where the movement of people, armored vehicles, trucks, artillery, evacuation vehicles, and even small infantry groups is constantly detected and targeted. The Russian army attempts to advance using small assault groups, relying on drones, artillery, FPV strikes, guided aerial bombs, and relentless pressure on various sectors. However, this very model renders its losses chronic.
In mid-May, the Ukrainian General Staff reported 233 combat engagements within a single 24-hour period, with the most intense attacks concentrated in the Pokrovsk and Huliaipole directions. During the same period, according to Ukrainian data, the Russian side deployed thousands of kamikaze drones and hundreds of guided aerial bombs, alongside massive shelling of positions and settlements. In the Kostiantynivka direction, dozens of attacks were recorded; in the Pokrovsk sector, Ukrainian forces halted over three dozen assault actions, and in the Huliaipole sector, nearly three dozen attacks were repelled.
This picture demonstrates that the Russian army has not lost its offensive momentum. It remains capable of generating pressure across multiple directions simultaneously. However, the nature of this pressure looks less and less like maneuver warfare. Rather than a swift operational breakthrough, it is a grinding push through the defense via the constant expenditure of manpower, equipment, and ammunition. While such a model can yield local results, its political effectiveness is plummeting: the higher the price of each kilometer, the lower the significance of that kilometer itself.
The Cost of Advancement Has Become the War's Key Indicator
Russia's strategy in recent years was built on a simple logic: if it is impossible to quickly defeat Ukraine, then it must be worn down through attrition. Now, however, it is increasingly evident that attrition works both ways. Ukraine suffers heavy losses and operates under a constant deficit, but Russia is paying a mounting price for its offensive. According to an assessment by Ukrainian Defense Minister Mykhailo Fedorov, Kyiv's objective is to push Russian casualties to at least 200 personnel for every square kilometer gained. In April, according to him, Russian casualties exceeded 35,000 personnel, and the cost of a single square kilometer reached levels that make the offensive extraordinarily expensive.
The crucial element here is not the dispute over the exact numbers, but the overall trend. According to estimates cited by Western military analysts, the Russian pace of advancement had been declining since late 2025, and in April 2026, Russia lost more territory than it gained for the first time in a long period, when calculating the net balance of control in the Ukrainian theater. It was also reported that the share of Ukrainian territory under Russian control dropped from a peak of nearly 27 percent in the initial weeks of the invasion to less than 20 percent in the spring of 2026.
This does not mean Ukraine has won the war. It does mean, however, that the Russian strategy of grinding down the opponent is no longer linear. Moscow can continue to apply pressure, but the outcome is no longer proportional to the expenditure of resources. The more Russia invests in the offensive, the less political return it receives. This is one of the primary signs of an exhausted model.
The Russian Army Advances but Fails to Solve Its Core Task
In classical military logic, an offensive should achieve one of three outcomes: the encirclement of major enemy forces, an operational breakthrough, or the destruction of the enemy's command and control system. In Ukraine, the Russian army most frequently achieves something else: the slow capture of ruined territory from which infrastructure, the population, logistics, and economic value have already been purged.
After months of fighting, a town or village turns not into a bridgehead for a grand maneuver, but into ruins that themselves require a garrison, supply lines, defense, and engineering support. Russia gains territory but does not gain operational freedom. It captures a space that it has itself rendered nearly useless for sustaining an offensive.
This was the case in several previous battles, and it is increasingly how the current front looks. The Russian army can attack Kostiantynivka, Pokrovsk, Lyman, Kupiansk, Huliaipole, or other directions, but Ukrainian defense is increasingly structured around turning Russian advancement into the most expensive process possible, rather than holding every point at all costs. This is not a war for a clean line on a map; it is a war for the attrition coefficient.
This is exactly where the Russian model hits its limit. It can withstand massive losses longer than many anticipated. However, it cannot indefinitely translate losses into strategic gains. With each passing month, the gap widens between the scale of the Russian effort and the actual results on the ground.
Drones Have Broken the Old Formula of Superiority
The Russian advantage in artillery, aviation, population, and industrial depth remains a significant factor. However, the drone war has drastically altered the balance. Ukraine, which possessed almost no large-scale domestic drone industry of its own in 2022, has transformed drone warfare into the foundation of its asymmetric defense by 2026. The Ukrainian Ministry of Defense stated that the country requires 120 billion dollars for defense in 2026, with the top priorities identified as air defense, corresponding missiles, domestic drones, and long-range ammunition. Ukraine also plans to produce over 7 million drones in 2026 and aims to extend its kill zone depth to 100 kilometers.
This fundamentally reshapes the mechanics of war. Previously, the rear of a battalion, brigade, or corps could be considered relatively secure. Now, rear logistics, warehouses, artillery positions, electronic warfare stations, command posts, repair bases, and supply routes are under constant threat. The drone has become more than just a weapon. It has become a cheap sensor, a reconnaissance tool, a strike platform, an instrument of psychological pressure, and an element of economic warfare.
Ukraine is also actively developing drone interceptors. In April 2026, the Ukrainian Defense Minister spoke of systems that allow for the remote control of interceptors over very long distances, striking targets hundreds or even thousands of kilometers away. Ukrainian officials estimated drone production for the previous year at approximately 4.5 million units, with production capacities continuing to expand.
This is precisely what makes the Russian offensive model less sustainable. Mass infantry, armor, and artillery were effective as long as they could concentrate, maneuver, and be resupplied. In this new environment, concentration becomes a vulnerability, movement becomes a risk, and logistics becomes a perpetual hunt.
Long-Range Ukrainian Strikes Alter the Economics of War
Another fundamental shift is the relocation of the war into the Russian deep rear. Ukraine is increasingly striking oil refining facilities, pumping stations, warehouses, military plants, microelectronics facilities, airfields, and energy infrastructure. These are not merely retaliatory strikes. They represent an attempt to change the financial and material cost of the war for Moscow.
In May 2026, it was reported that following Ukrainian strikes, virtually all major oil refineries in central Russia were forced to halt or reduce fuel production. Affected facilities included refineries in Kirishi, Moscow, Nizhny Novgorod, Ryazan, and Yaroslavl. The combined capacity of the enterprises that completely or partially halted operations exceeded 83 million tons per year, accounting for about a quarter of Russia's total oil refining capacity. These plants supplied more than 30 percent of gasoline production and roughly a quarter of diesel production.
This is particularly critical because Russia's war is not funded solely by the defense line item in the national budget. It relies on fuel, railroads, repair bases, oil and gas revenues, export logistics, and the domestic fuel market. By striking these nodes, Ukraine attacks not just the military machine, but its economic lifeblood.
In May, Russian oil and gas revenues may have seen a temporary increase amid a spike in global prices linked to geopolitical tensions around Iran, but for the January-May period, they were still estimated to be roughly a third lower than the previous year. The Russian budget for 2026 projected 8.92 trillion rubles in oil and gas revenues out of total revenues of 40.283 trillion rubles. Simultaneously, Russian forecasts for oil and gas production and exports for 2026-2029 were revised downward, with sanctions, Ukrainian strikes on energy infrastructure, and an overall deterioration of economic dynamics cited as key factors.
This does not render the Russian economy helpless. It does, however, make it less flexible. The war is ceasing to be an expense confined to the front line. It is turning into a struggle over the capacity to reproduce fuel, ammunition, transport, repairs, foreign currency earnings, and industrial resilience.
The Russian Economy Has Not Collapsed but Has Ceased to Be a Comfortable Base for War
One of the mistakes made by many observers was expecting a rapid economic collapse in Russia. This did not happen. The Russian economy adapted, restructured trade flows, expanded military production, redirected labor, strengthened state control, and learned to survive under sanctions. However, adaptation does not equate to economic health.
According to SIPRI estimates, Russian federal expenditures on the war and other military needs reached approximately 16 trillion rubles in 2025, or 7.5 percent of GDP. In 2026, planned military spending was reduced to 14.9 trillion rubles, or 6.3 percent of GDP, but the budget structure itself remains wartime-focused, and the possibility of revising expenditures throughout the year persists.
In May 2026, Russia lowered its GDP growth forecast for 2026 from 1.3 percent to 0.4 percent, and the economy reportedly contracted by 0.3 percent in the first quarter, marking the first decline since early 2023. Cited reasons included sanctions, high interest rates, tax pressure, and exhaustion following the growth fueled by military expenditures.
This is the key point. The Russian economy does not necessarily have to collapse for its military model to begin malfunctioning. It is sufficient that its room for maneuver is shrinking. Expensive credit hinders the civilian sector. A labor shortage hits industry. Military salaries and payouts draw people out of the regional economy. The state is forced to simultaneously finance the front, maintain social stability, subsidize sensitive sectors, and rein in inflation.
Such a system can function for a long time, but it becomes increasingly inefficient. Instead of collapsing, it freezes. This may be even more dangerous for the Kremlin: while there is no formal collapse, each new year of war requires an increasingly heavy mobilization of resources.
Ukraine Is Also Fighting to Its Limits
It would be a mistake to view the situation solely as the unilateral exhaustion of Russia. Ukraine is also paying a tremendous price. Its wartime budget relies heavily on external support. In the draft budget for 2026, Kyiv projected state expenditures and financing at 4.8 trillion hryvnias, with defense and security set to receive 2.8 trillion hryvnias, or 27.2 percent of GDP. The authorities are directing all domestic financial resources, including taxes, duties, excises, and domestic borrowing, toward resisting Russian aggression.
The Ukrainian parliament approved the 2026 budget with a stark emphasis on defense: approximately 27.2 percent of GDP was allocated to the military, weapon production, and procurement, while the overall budget deficit was estimated at 18.5 percent of GDP. Kyiv required more than 45 billion dollars in external financing for 2026.
The European factor is becoming decisive here. In April 2026, the Council of the EU agreed on a 90-billion-euro loan to Ukraine for 2026–2027 to cover urgent budget and defense needs, with approximately 60 billion euros intended to support the Ukrainian defense industry and defense procurement. This is not merely assistance; it is an attempt to integrate Ukraine into the European defense-industrial complex so that the war does not depend solely on the volatile political will of individual capitals.
Yet even this aid does not eliminate the challenges. Ukraine must simultaneously hold the front, restore its energy sector, protect its cities, replenish its army, preserve its economy, combat corruption, maintain its social fabric, and modernize its defense industry. Its warfare model is technologically effective but demographically and financially vulnerable.
A Sign of Strength and Powerlessness
When frontline warfare fails to produce a decisive outcome, Russia intensifies its missile and drone terror against Ukrainian cities. This is not a random emotional reaction but part of a strategy: to strike energy infrastructure, the economy, public morale, administrative centers, cultural memory, and symbols of statehood. Simultaneously, such strikes demonstrate that Moscow is attempting to compensate for its inability to achieve a swift military breakthrough by striking civilian spaces.
On May 24, 2026, Russia launched one of its largest strikes against Ukraine, reportedly deploying 90 missiles and around 600 attack drones, including the Oreshnik ballistic missile. The primary target was Kyiv, where residential buildings, schools, a market, water infrastructure, government buildings, and cultural sites were damaged, resulting in fatalities and dozens of injuries. The Russian Ministry of Defense claimed it was targeting military objectives, command posts, airfields, and defense-industrial enterprises, but the destruction in urban environments once again exposed the real nature of this war.
Such strikes have a dual effect. They inflict real losses on Ukraine and force the expenditure of scarce air defense missiles. However, they also strengthen the arguments of those demanding expanded assistance for Kyiv and harsher pressure on Moscow. Russia attempts to break the Ukrainian will through fear, but each new strike on Kyiv, Kharkiv, Odesa, Dnipro, or other cities reinforces the image of the war as a colonial punitive campaign.
The Diplomatic Stalemate Intensifies the Significance of the Battlefield
At the diplomatic level, the war is also in a phase of viscosity. The United States under President Trump attempted to play a mediating role, but by May 2026, American representatives acknowledged that the negotiation process had yielded no tangible results and was effectively on pause. Secretary of State Marco Rubio stated that Washington was ready to return to mediation if a chance for productive negotiations emerged, but was not interested in an endless cycle of meetings without outcomes.
This is important: diplomacy has not vanished, but it has once again become dependent on military dynamics. Russia calculates that pressure on the front and strikes on cities will force Ukraine and the West to accept Russian terms. Ukraine calculates that technological attrition, strikes deep inside Russia, and European aid will alter the balance of power. In this situation, negotiations become not an alternative to war, but a continuation of war by other means.
This is precisely why the question of the exhaustion of the Russian model is practical rather than academic. If Russia is capable of continuing its offensive without a strategic breakthrough, the war could drag on. If Ukraine can sharply increase the range, accuracy, and volume of its strikes, the Russian model will begin to degrade faster. If the West reduces support, Russia will gain a chance to rely on mass once again. If Europe secures long-term financing and industrial cooperation with Ukraine, the Russian advantage in scale will begin to lose its decisive importance.
What Exactly Has Evolved to Its Limit
Russian missiles have not run out. Russian mobilization capabilities have not run out. Russian money has not run out. Russian reserves of brutality have not run out. But the previous certainty that mass always defeats a system has evaporated.
The Russian model is exhausting itself in five dimensions:
The first is operational. Russia increasingly advances without the ability to rapidly exploit success. A local breakthrough runs into drones, mines, artillery, a lack of mobile reserves, the exhaustion of assault units, and the depth of Ukrainian defense.
The second is human. Casualties have become a permanent mechanism of the war rather than an episodic cost of advancing. According to Ukrainian data as of May 25, 2026, estimated Russian casualties since the beginning of the full-scale invasion reached approximately 1,356,940 personnel killed and wounded, along with tens of thousands of pieces of equipment, artillery, vehicles, and drones. These figures represent a Ukrainian estimate and must be viewed precisely as the assessment of a warring party, but the scale of the trend is obvious. Independent Russian researchers by May 2026 had confirmed the deaths of over 7,000 Russian officers, which also demonstrates the prolonged erosion of the army's core cadre.
The third is economic. Russia's military economy has not collapsed, but it has ceased to be a normal economy. It depends increasingly on the budget, security contracts, oil and gas revenues, forced adaptation, and political control.
The fourth is technological. Russia learns quickly, scaling up drones, electronic warfare, and missiles, but Ukraine has imposed a war where a cheap weapon can destroy an expensive platform, and distributed innovation can move faster than a state vertical.
The fifth is political. Russia failed to achieve Ukraine’s capitulation, a fracture in Ukrainian society, the collapse of Western support, or the recognition of its territorial claims as the new norm. A war conceived as a demonstration of imperial power has become a prolonged proof of the limits of that power.
What Has Not Yet Been Exhausted
However, the exhaustion of a model must not be confused with immediate defeat. Russia still possesses a massive apparatus of coercion. It has the population, territory, defense industry, nuclear blackmail, missiles, allies assisting in sanctions evasion, experience in regional mobilization, and a readiness to wage war without moral constraints. It can maintain a high level of violence for years, especially if global conditions assist through high oil prices, political crises in the West, and public fatigue.
Ukraine, conversely, has no right to complacency. The drone revolution does not replace people. Long-range strikes do not replace air defense. European loans do not replace a sustainable industrial cycle. Technological superiority in specific sectors does not eliminate the shortage of infantry, combat engineers, artillery barrels, engineering vehicles, and city protection systems.
Therefore, the correct conclusion is this: the Russian model is not dead, but its peak efficiency has already been reached. Moving forward, it can continue the war, but it finds it harder and harder to win it in the form the Kremlin envisioned.
The Ultimate Outcome
The Russian war against Ukraine increasingly resembles a gigantic mechanism that continues to function because it is continuously fed with people, money, metal, oil, fear, and propaganda. However, this mechanism no longer produces a decisive outcome. It produces destruction, losses, ruins, new cemeteries, budgetary strain, and international isolation.
Ukraine is also exhausted, but its model is more adaptive. It is not stronger than Russia in the conventional sense. It is not wealthier, larger, or immune to mistakes. However, it changes its methods of warfare faster. Russia attempts to win through mass. Ukraine attempts to make mass vulnerable. In this clash, not only the fate of the front is being decided, but the fate of 21st-century military logic as a whole.
If Russia cannot translate numerical and resource superiority into an operational breakthrough, its model will definitively turn into a machine of self-attrition. If Ukraine receives sufficient industrial, financial, and technological depth, the Russian strategy to outlast everyone will begin to work against Russia itself.
That is why the question is no longer whether Russia can still advance. Yes, it can.
The correct question is different: can it advance in a way that leads to victory?
As of today, the answer is becoming increasingly harsh for Moscow: Russia is still capable of continuing the war, but its model is increasingly incapable of winning the peace after the war. A war that opens no political exit sooner or later turns into a demonstration of a strategic stalemate rather than an instrument of power.
