Russian Casualties Are Becoming Unsustainable: The Numbers Behind the War's Vibe Shift

In 1989, the final Soviet tanks rolled out of Afghanistan, ending what was then Moscow’s bloodiest war since 1945. Across the preceding decade, more than fifteen thousand Soviet troops had perished, a toll so vast it shook Soviet society to its foundations. Not for nothing did some analysts call it the USSR’s Vietnam.

Four decades later, those Soviet casualty figures from Afghanistan seem almost quaint. Today, more Russians are dying in Ukraine in a single month than died across the entire ten-year Soviet-Afghan War. And the rate of death is only increasing, as first-person-view drones saturate the frontlines, making evacuation of the wounded nearly impossible. According to a recent Ukrainian intelligence assessment, Moscow’s forces are now suffering two fatalities for every one soldier wounded.

If you know anything about warfare, you know that figure is a complete inversion of how the wounded-to-dead ratio normally works on modern battlefields. Yet staggering as that statistic is, it pales beside the recent estimates of total Russian deaths. While precise figures are known only to the Kremlin, it now appears that by the end of 2025, Russia had suffered over 350,000 fatalities in Ukraine, a number the Center for Strategic and International Studies has called “unparalleled for a major power since World War II.”

That single fact frames the question this analysis sets out to answer: how long can Russia keep absorbing such eyewatering casualties before the war’s arithmetic turns decisively against it?

High Costs, Low Gains

In a recent piece, the Financial Times spoke with two officials close to Vladimir Putin who reported that the Russian president had become obsessed with seizing the rest of Donbas from Ukraine. According to those sources, the army’s high command had convinced him this could be accomplished by autumn. As one official put it: “I have been pushing him to end at the current front lines. But he keeps saying, ‘No, I can’t compromise on this.’”

For anyone who hasn’t followed the war closely this year, it is hard to overstate how unlikely that timeline is. Russian forces are not so much inching forward as millimetering. Using data from the Institute for the Study of War, one count put Moscow’s gains at a mere 220 square kilometers so far this year, while Ukraine has recaptured 189. To put that in perspective, 220 square kilometers is slightly smaller than the island of Nantucket.

The cost of taking even that sliver of ground has been enormous. By one estimate, 316 Russian soldiers have been killed or seriously wounded for every square kilometer of land seized in the Donbas this year. Speaking to Sean Hannity while en route to China, Secretary of State Marco Rubio said that in 2026, “The Russians are losing 15-20,000 soldiers a month dead. Not injured, dead. It’s a bad war.”

A Word of Caution on Maps

Serious caveats apply before reading too much into any of this. While the amount of land conquered can be a useful shorthand for how a war is progressing, it does not by itself reveal the real state of things. If it did, the only conclusion anyone studying the German spring offensive of 1918 could possibly draw would be that Germany was about to win the First World War. Germany, of course, has not historically excelled at winning world wars.

That deliberately absurd example carries a real lesson. Just because one side is taking ground at an unusually slow or fast tempo does not mean we can predict a war’s outcome from that metric alone. Where Russian advances are concerned, the pace could yet pick up. As spring becomes summer and foliage grows denser, it becomes increasingly difficult for Ukrainian drone operators to detect enemy movement, which could open the door to faster gains.

The slow tempo of Russian advances, in short, is only one strand of the recent shift in mood around the war. The more alarming strand is the casualty curve.

The Diverging Casualty Curves

On the anniversary of the invasion earlier this year, The Economist published its own modeling of Russian casualties, suggesting that as many soldiers had died between February 2025 and February 2026 as had perished across the first three years of the war combined. Other estimates put the figure at as many as one thousand Russian soldiers taken off the board each day, a count that includes killed, wounded, and captured.

This matters because most analysts agree it is the reverse of Ukraine’s trend. For Kyiv’s forces, the opening months of the war and the failed counteroffensive of 2023 were the most catastrophic periods for casualties. The result is a Ukrainian death toll that is lower than Russia’s in absolute terms but higher as a share of population. CSIS analysis suggests one in twenty-five Russian men aged 18 to 49 have been killed or wounded, against a staggering one in sixteen Ukrainian men in the same bracket.

The decisive point is the direction of travel. Ukraine’s losses are sharply slowing while Russia’s are sharply accelerating. Understanding why that is happening, and what it means for the war’s trajectory, is the heart of the matter.

Days of Blood

On the modern battlefield, a rough rule of thumb holds that for every three soldiers wounded, one will be killed. It is only a guide, and it does not apply everywhere. A highly capable military with advanced evacuation and medical capabilities tends to push the odds further in its favor; a quick look at US casualties in Iraq suggests a ratio closer to seven wounded for every one killed.

That is what makes the recent Ukrainian intelligence estimates so shocking. After multiple years in which meat-grinder tactics produced something like two Russians wounded for every one killed, the numbers appear to have inverted. According to Ukrainian data, “Out of 100 percent of losses, 62 percent are killed and 38 percent wounded.” That would mean roughly two Russian soldiers now die for every one wounded, which the Kyiv Independent described as “one of the deadliest killed-to-wounded ratios seen in modern warfare.”

The obvious temptation is to dismiss this as Ukrainian propaganda; Kyiv’s incentive to talk up Russian losses is plain. But there are good reasons to believe something genuinely horrific may be underway, and that after a long era in which wars grew gradually less deadly, the trend may be reversing. The reason comes down largely to a single word: drones.

How Drones Inverted the Ratio

The frontlines are now so saturated with small FPV drones that getting to and from the point of contact has become a grotesque, drawn-out ordeal. Depending on location, anyone approaching the front may have to spend the final five to twenty-five kilometers being hunted from the air.

That includes medical evacuation teams. Extracting the wounded under fire was always dangerous and difficult, but it has now become near impossible. Wounded soldiers can remain stranded for hours, which naturally collapses their chances of survival. Phillips O’Brien, Professor of Strategic Studies and head of the School of International Relations at the University of St Andrews, told the Kyiv Independent that the inverted ratio “does not seem implausible to me because of the accuracy of first-person view (FPV) drones, and the fact that the battlefield makes it very difficult indeed for wounded soldiers to be evacuated.”

Ukraine faces the same problem, but it is less acute for several reasons. Kyiv has again pulled ahead in the drone race and is now using unmanned ground vehicles to evacuate its wounded. Ukraine is also currently the defending force, and in a fight between peers or near-peers, the attacker, here the Russians, would typically be expected to take more casualties.

A Calculus of Indifference

There is another, grimmer factor at work: the Kremlin appears to place less value on its soldiers’ lives. This war has produced innumerable accounts of Russian officers using their men as cannon fodder or failing to evacuate the wounded out of sheer indifference. Carry that attitude into a world where drones are already making evacuation almost impossible, and it becomes easy to see how many wounded troops who could have been saved end up bleeding to death in a field in the Donbas.

Beyond drones, the Russians also have to contend with Ukraine’s new fortifications. After years in which incompetence and corruption left certain sections of the front barely protected, Kyiv appears to have finally organized itself. Analyst Clement Molin has written about areas with “between two and five lines of defense behind the front lines on the eastern front,” and of fields strewn with barbed wire that make advancing almost impossible.

In effect, the Russians are now living through what Ukrainians endured during their failed push against the Surovikin lines in the 2023 counteroffensive, with the added nightmare of being hunted by drones the entire way.

The Recruitment Squeeze

All of this aligns with Ukraine’s stated goal for 2026: to take out more Russian troops each month than Moscow can recruit. After years in which the Kremlin could count on between 30,000 and 35,000 new bodies entering the ranks every month, recruitment has tailed off to between 24,000 and 30,000. At the same time, total monthly casualties, counting killed, wounded, and captured, have risen to around 35,000.

As Rubio framed it again: “The Russians are losing five times as many soldiers a month as the Ukrainians are, and Ukraine is a smaller country and a smaller army for that matter.”

This ratio does not, on its own, mean the Kremlin’s forces are near collapse. Throughout modern history, big offensive pushes have always produced a sharp spike in casualties, even when the attacker ultimately wins. The signal emerges only when the factors are combined. It is not just that Russia is advancing so slowly that the phrase “snail’s pace” would insult molluscs, nor just that it is suffering a terrible uptick in casualties for minor territorial gains. It is that all of this is happening at once.

The Converging Pressures

The convergence is what produces the war’s recent vibe shift. Ukraine has pulled ahead in the drone race again. Putin’s popularity recently hit a wartime low, reinforcing the expectation that he will be unwilling to order a second mobilization. Ukrainian long-range drones are now able to penetrate the air defenses around Moscow, and the Russian economy looks increasingly grim, not catastrophic, but certainly in the doldrums.

Taken together, these factors suggest the goal of seizing the whole of Donbas by autumn may be wildly optimistic. Russia may still make gains during its summer offensive, but they are likely to fall short of the Kremlin’s hopes.

This is no cause for triumphalism. As Lawrence Freedman noted on his Substack, Ukraine has serious problems of its own. Chief among them is Kyiv’s ongoing inability to recruit enough troops, leaving a relatively porous frontline policed largely by drones. Those drones complicate Russian advances, but a shortage of men means Ukraine cannot exploit Russian weakness with anything beyond extremely localized counterattacks.

Add resentment toward a high command seen as out of touch and too fixated on holding ground at all costs, and the reports of skilled officers resigning in frustration become easier to understand.

The Technological Wildcard

Then there is the relentless technological race. In 2022 and 2023, few could have predicted that FPV drones would replace artillery at the front, or that naval drones would let Ukraine, a country without a navy, claim victory over the Russian Black Sea fleet.

And Russia is good at drones. At various points in this war, Moscow has held the technological advantage over Ukraine. Just because the Ukrainians have pulled ahead again does not mean those positions cannot reverse by autumn. Nor should anyone discount the possibility of a breakthrough that drastically diminishes the drone threat altogether.

Even with all of those caveats, there are reasons to believe Moscow’s forces may be reaching a point of diminishing returns. The largest is the one this analysis opened with: Russian combat deaths, not casualties but actual deaths, have now reached numbers that may simply be unsustainable.

Bring Out Your Dead

Before any discussion of Russian losses, it bears repeating that the true total is unknown anywhere outside the Kremlin. Moscow has published its casualty figures exactly once, back in 2022, and even then the number was comically low. Any attempt to estimate the true scale therefore involves statistical modeling, a range of numbers, and some potentially heroic assumptions.

One source, however, gives accurate figures, not for the overall total, but for a pure minimum baseline: the Named List. A joint project of the independent Russian outlet Mediazona and the BBC, it is a simple count of all confirmed Russian deaths in the fighting so far. Using obituaries, photographs of gravestones, and regional bulletins, it builds a minimum baseline of Russian dead. There are no models and no estimates; for a name to be included, the person was demonstrably real and demonstrably died fighting in Ukraine.

Mediazona updates the list every two weeks. At the time of writing it stood at 217,808. That is nearly 220,000 dead, not dead or wounded, but dead, and it includes only Russian citizens. Foreign mercenaries, North Korean soldiers, and fighters for the so-called Donetsk and Luhansk People’s Republics are excluded.

Putting the Numbers in Historical Context

Everyone working on the Named List agrees it is a massive undercount. Yet even if it were the full total, over 217,000 deaths for a major power in the modern era is extraordinary. For perspective, American deaths in Vietnam, including killed in action and those lost to accidents or illness, totaled 58,220.

At a bare minimum, then, Russia has lost more than three-and-a-half times as many men in Ukraine as the United States lost in the entire Vietnam War. Put another way, the official combined total of all US fatalities in Vietnam, Korea, and World War One is 211,310, still fewer than total Russian deaths over these last four years.

To get closer to the real toll, we can turn to another Mediazona project, run in collaboration with Meduza: the Probate Registry Count. By Russian law, all inheritance cases must be made publicly accessible in a database. Mediazona’s team cross-references that registry against the Named List to build a statistical model that, in their words, “calculate(s) the probability of inclusion in the registry for each age and social group.”

The headline figure is what matters here. In their last update, the team asserted that between the start of the full-scale invasion and the end of 2025, around 352,000 Russian soldiers had died. That figure again excludes foreign fighters and those from breakaway regions, and it omits the first five months of 2026, a period in which Russian deaths spiked sharply.

More Dead Than America Lost in World War II

Even with those exclusions, 352,000 is a staggering number. Across the whole of the Second World War, American forces suffered 405,399 fatalities. If Rubio’s range of 15,000 to 20,000 new deaths a month is accurate, and the figure of 352,000 Russian dead by 31 December 2025 is also accurate, then deaths among Moscow’s forces in Ukraine now exceed the entire total of US fatalities in World War II.

Consider what that comparison contains. The D-Day landings. The Battle of the Bulge. Okinawa and Iwo Jima. Pearl Harbor. The countless American lives lost in smaller battles and ship sinkings rarely remembered today. All of those iconic, bloody moments together would still not add up to the loss of Russian life in Ukraine since 2022.

And for what? Those 400,000 American dead in World War II could at least pass into the hereafter having contributed to genuine victories: the dismantling of the Nazi project in Europe and the defeat of Imperial Japan in Asia. The Russian dead in Putin’s Ukraine war have contributed to what, exactly? At the end of 2022, Moscow controlled not quite twenty percent of Ukrainian territory, Crimea included. By mid-May 2026, Russia controls roughly twenty percent of Ukrainian territory.

Is Anyone Winning?

Meanwhile, Putin’s other war aims remain unfulfilled. Parts of Donbas stay in Ukrainian hands. NATO has not retreated but expanded. The same government still sits in Kyiv. Russia is now economically dependent on China. The Kremlin’s most devoted supporters will surely try, but it is hard to construct any serious argument that Russia is “winning.”

That does not mean Ukraine is winning either. A full Ukrainian victory would require retaking the land conquered since the start of the full-scale invasion, a prospect that currently seems remote. But given the fear in February 2022 that Kyiv would fall within days or weeks, the fact that Ukraine is still standing four years later with most of its territory intact may at least count as a win of sorts.

The pressing question is what happens when the Kremlin finally recognizes that victory is likely impossible. Honestly, it is difficult to say. There is a scenario in which summer conditions let the pace of Russian gains pick up, not by much, but enough to reinforce Putin’s belief that the war can be won if he simply keeps fighting. In that case, expect the grinding to continue for the foreseeable future.

What Comes Next

Equally, there is a scenario in which the spiking death toll and falling recruitment cause Russia’s offensive to run out of steam without accomplishing much. Should 2026 close with parts of Donbas still in Ukrainian hands, one can only hope that even the vampire in the Kremlin might be persuaded to throw in the towel.

Then come the lower-probability but more dramatic possibilities. On the positive side, Russia’s political consensus might undergo a “slowly, and then all at once” collapse, prompting a change in Moscow’s goals. On the negative side, a cornered Putin might do what he has always done when cornered: raise the stakes, perhaps even by launching an assault on a NATO member.

All of which is a long way of admitting that we do not know. Whatever happens will, in retrospect, come to seem obvious, the inevitable product of forces currently invisible or hard to discern through the fog of war. But this much is clear: right now, the tempo of the war is turning against Russia.

Blessed with an overwhelming manpower advantage, the Kremlin has chosen to squander it by sending its sons and brothers to die needless deaths in a Ukrainian field. Authoritarian societies can absorb a great deal of hardship, perhaps more than democracies, but they cannot take infinite punishment. Unless Putin changes tactics soon, the spiraling death toll may eventually do to his neo-empire what the coffins returning from Afghanistan once did to the Soviet Union.

Frequently Asked Questions

How many Russian soldiers have died in Ukraine?

The true total is known only to the Kremlin. The BBC-Mediazona “Named List” of individually confirmed dead stood at 217,808 at the time of writing, a figure regarded as a significant undercount. A separate Mediazona-Meduza statistical model based on Russia’s probate registry estimated around 352,000 Russian dead between the start of the full-scale invasion and the end of 2025, excluding foreign fighters and the first five months of 2026.

Why is Russia’s killed-to-wounded ratio considered so unusual?

On modern battlefields, a rough rule holds that for every three soldiers wounded, one is killed; well-equipped militaries do even better, with US forces in Iraq seeing about seven wounded per death. Ukrainian intelligence reports the Russian figures have inverted to 62 percent killed and 38 percent wounded, meaning roughly two Russians now die for every one wounded, which the Kyiv Independent called one of the deadliest such ratios in modern warfare.

What is causing so many wounded Russian soldiers to die?

The primary driver is FPV drone saturation. Frontlines are so thick with first-person-view drones that the final five to twenty-five kilometers approaching the front become a gauntlet. Medical evacuation has become near impossible, leaving wounded soldiers stranded for hours and collapsing their survival odds. Strategic studies professor Phillips O’Brien said the inverted ratio is plausible given drone accuracy and the difficulty of evacuation.

How much territory has Russia gained, and at what cost?

Using Institute for the Study of War data, one count put Russian gains in 2026 at around 220 square kilometers, slightly smaller than Nantucket, against 189 square kilometers recaptured by Ukraine. The estimated cost is 316 Russian soldiers killed or seriously wounded for every square kilometer of Donbas seized.

How do these losses compare to past wars?

The confirmed minimum of 217,808 dead is more than three-and-a-half times the 58,220 US fatalities in the entire Vietnam War, and exceeds the combined 211,310 US fatalities in Vietnam, Korea, and World War One. The 352,000 modeled estimate, combined with Rubio’s figure of 15,000 to 20,000 deaths a month in 2026, would mean Russian deaths in Ukraine now exceed the 405,399 American fatalities of the entire Second World War.
