More than four years into the war it began, Russia has absorbed a scale of military loss that no major power has experienced since the Second World War — and to little visible end. Since the start of 2024 its forces have gained less than 1.5 percent of Ukraine, and this spring, by the battlefield mapping most analysts treat as authoritative, they began losing ground outright.
The headline figure is staggering on its own. By the spring of 2026, a range of independent and government estimates had converged on a total of roughly 1.2 million Russian casualties — killed, wounded and missing — since the February 2022 invasion: about 1.17 million by the U.K. Ministry of Defense's December 2025 count, 1.2 million by Western officials briefing Bloomberg in February 2026, and, at the wider end, 1.1 million to 1.5 million by The Economist in May 2026. The Center for Strategic and International Studies, which reached the same 1.2 million mark, framed the broader point bluntly: "No major power has suffered anywhere near these numbers of casualties or fatalities in any war since World War II."
But raw totals obscure as much as they reveal. To understand what 1.2 million casualties means, it helps to set Russia's war against the conflicts it most resembles — and the ones Americans remember best. The closest analogy is not the Second World War the Kremlin invokes but the First: the trench-bound, artillery-dominated attrition of the Western Front, where armies bled by the hundred thousand for a few miles of churned earth. The Soviet Union's own catastrophe, America's bloodiest war at home, and its hardest wars abroad — the Civil War, World War II, Korea and Vietnam — fill out the picture.
Killed and wounded: a war of attrition, not annihilation
Casualty totals lump together two very different things, and the distinction matters.
The dead are the hardest number to pin down, and the sources that try diverge sharply. The BBC's Russian service, working with the independent outlet Mediazona, had confirmed roughly 223,500 Russian war dead by name as of late May 2026 — a documented floor, not a ceiling, since many deaths go unrecorded. Mediazona and Meduza's statistical model, which extrapolates from inheritance records and other administrative data, put the figure closer to 352,000 in May 2026. CSIS estimated 275,000 to 325,000 killed through December 2025. At the high end, Britain's GCHQ signals-intelligence agency suggested in May 2026 that the toll was approaching 500,000.
Taken together, the most defensible reading is that somewhere between 250,000 and 350,000 Russian soldiers have died, with the true number plausibly higher and almost certainly not lower than the 220,000-plus confirmed by name.
The wounded are far more numerous. The arithmetic of modern combat medicine — roughly three to four men maimed for every one killed — implies on the order of 800,000 to one million Russian wounded, many of them permanently disabled by drone strikes, artillery and mines. The U.K. Ministry of Defense's mid-2025 breakdown of roughly 250,000 killed against 700,000 wounded fits that pattern.
The contrast is starkest against the wars within living memory for most Americans. In nearly nine years in Iraq, the United States lost about 4,400 troops killed — an average of roughly forty a month; across two decades in Afghanistan, about 2,400, or closer to ten a month. Russia, at the pace of 2025, has been losing on the order of ten thousand men killed every month. In its deadliest stretches it loses more soldiers in a single month than the United States lost in Iraq and Afghanistan combined across twenty years; counting the wounded, it absorbs the equivalent of America's entire toll in those two wars — roughly 6,800 dead and 53,000 wounded — about every two months.
Measured against whole wars rather than monthly rates, the comparison is just as stark. Russia's roughly 1.25 million killed and wounded in Ukraine are about equal to all American casualties in the Second World War and Vietnam combined — its largest war and one of its most divisive, about 1.29 million in all. Britain reached that scale only in its world wars: Russia's four-year toll already exceeds Britain's losses in the whole of the Second World War, and equals roughly half of those in the First — the bloodiest war in British history, which alone cost the United Kingdom some 2.5 million casualties.
For all that scale, this has been less a war of great battles than of relentless, grinding attrition — bodies traded for yards, at one of the slowest rates of advance of any major offensive in the past century.
The closest parallel: the trenches of 1916
For all the Kremlin's invocations of 1945, the war Ukraine most resembles is the one fought three decades earlier. The Western Front of 1915–17 was the original war of industrial attrition: two entrenched armies, dominated by artillery and machine guns, grinding each other down across a fortified no-man's-land where the defense almost always held and a mile of ground could cost a hundred thousand men. Drones and satellite reconnaissance have replaced cavalry and observation balloons, but the essential logic — that modern firepower makes movement lethal and stalemate the natural state — is the same.
The likeness isn't only in how the war is fought; it's in the numbers. CSIS calculated that Russia's main 2024–25 offensive, around Pokrovsk, advanced an average of about 70 meters a day — slightly slower than the British at the Somme, who gained roughly seven miles over 141 days, or about 80 meters a day. The Somme, the byword in English for futile slaughter, cost more than a million casualties on both sides — about 420,000 British Empire, 200,000 French and at least 450,000 German — for that seven miles, about 90 casualties for every meter gained. Its first day, July 1, 1916, remains the bloodiest in the history of the British Army: nearly 60,000 casualties, some 19,000 of them dead, before nightfall. At Verdun, the Germans and French fought for ten months to a virtual draw, with roughly 700,000 to 800,000 casualties between them and some 300,000 dead.
Where the analogy breaks is tempo. The Western Front concentrated its horror into set-piece battles: the Somme generated its million casualties in four and a half months, a rate above 200,000 a month. Russia's losses, running near 35,000 a month at their 2025 peak, are an order of magnitude lower. Ukraine is less a single Somme than a Somme stretched thin and run continuously for four years — the same attritional logic, the same primacy of the defense, but metabolized slowly, month after grinding month, rather than spent in one catastrophic summer.
The same holds in space. The Somme packed its dead into a sliver of Picardy: the attacking Allies lost something on the order of 6,000 men for every square mile they took, against roughly 200 per square mile for Russia's gains in 2025 — a battlefield perhaps thirty times denser with casualties per yard of ground. Russia has reproduced the Somme's crawl without its concentration. The front itself is longer and far more thinly held than the Western Front ever was: Ukraine's active line runs about 1,000 kilometers, against roughly 700 for the Western Front of 1914–18, yet the contested sectors are manned at perhaps 700 troops a mile, where the Somme packed in something closer to 10,000 a mile on each side. This is attrition spread thin, not concentrated.
The Soviet shadow: a different order of magnitude
The Kremlin wraps its war in the memory of the Great Patriotic War, and the comparison is instructive — though not in the way Moscow intends. It exposes how different industrial-age mass slaughter was from the present conflict.
According to the standard scholarly tally compiled by Russian Col. Gen. Grigori Krivosheev from declassified Soviet archives, the U.S.S.R. suffered about 8.7 million military deaths between June 1941 and May 1945 — roughly 6.3 million of them in direct combat — with some independent historians putting the figure as high as 11 million or more. More than 15 million Soviet soldiers were wounded. Including civilians, the Soviet Union lost some 27 million people.
Compress that into time and the gulf becomes vivid. The Soviet-German war lasted about 47 months. At 8.7 million military dead, the Red Army was losing on the order of 185,000 soldiers killed every month — more than the total number of Russian dead confirmed by name across the entire four-plus years of the Ukraine war. The Soviet Union lost more men killed in any given two-month stretch of 1941–45 than Russia has lost in all of Ukraine. A single 1941 encirclement, the Battle of Kyiv, cost the Red Army more than half a million men in a matter of weeks.
The point is not that Russia's losses are small. It is that the Soviet template Putin invokes belonged to a vanished era of million-man front lines and headlong frontal assault. Russia today is bleeding at a fraction of the Soviet rate — and still cannot replace its losses, which since December 2025 have for the first time outpaced recruitment.
Against the wider Second World War — and the United States
For an American frame of reference, the relevant comparison is the United States' own war.
The United States lost about 405,000 service members dead in the Second World War, with roughly 671,000 wounded, over the 44 months between Pearl Harbor and the Japanese surrender — a global, two-front war fought across Europe, North Africa and the Pacific. Britain and its empire lost about 451,000 dead. Germany, fighting on multiple fronts, lost something between 4.3 and 5.3 million military dead.
Set against that ledger, Russia's death toll in Ukraine — 250,000 to 350,000 by the central estimates — is approaching what the United States lost in all of World War II, but over a longer span and to no comparable strategic end. Russia's wounded alone, approaching a million, exceed total American casualties, killed and wounded, in that war. And the United States accomplished the defeat of Nazi Germany and Imperial Japan in less time than Russia has now spent failing to capture the Donbas.
The monthly comparison still sharpens the point, if it is stated carefully. The United States lost about 9,000 men killed a month in the Second World War — roughly 24,000 a month counting the wounded. Russia's casualty rate ran near 35,000 a month through 2025, by CSIS's count, and held above 30,000 into early 2026, according to British military officials, with a single-month spike in March. Russia is losing men somewhat faster than America did in the most destructive war in human history — though by deaths alone, perhaps 10,000 to 12,000 a month against America's 9,000, the two are closer than the casualty totals imply. (Russia's 30,000-a-month figure is killed and wounded together; the dead are a fraction of it.)
America's bloodiest war
No conflict has cost American lives like the Civil War. For a century the accepted toll was about 620,000 dead; recent demographic work using census data has pushed the likely figure to roughly 700,000 and perhaps as high as 750,000 — roughly as many as the country lost in all its other wars combined, from the Revolution through Vietnam. About two-thirds died not in battle but of disease, in the filthy camps of armies that had not yet accepted germ theory; direct combat deaths numbered perhaps 205,000, with another 475,000 or so wounded.
That disease toll marks the real distance between 1863 and the present. Strip it away and the comparison tightens: Russia's combat dead in Ukraine — a quarter-million or more — already exceed all the men killed outright in battle on both sides of the Civil War. But the United States bled that toll fighting itself, on its own soil, in a war that decided whether the country would survive. Russia has bled a comparable one fighting a neighbor a fraction of its size.
Korea and Vietnam: the wars Americans remember as costly
If World War II feels remote, Korea and Vietnam may be the more visceral yardsticks. Korea, the "forgotten war," killed about 36,500 American service members and wounded some 103,000 in three years of fighting. Vietnam, whose memorial wall in Washington bears 58,220 names — the official Defense Department count of the dead — wounded about 153,000 badly enough to require hospitalization, and more than 300,000 in all. Those losses, accrued across nearly a decade of major involvement from 1965 to 1973, fractured a generation and a presidency.
Set beside Ukraine, both shrink. Russia has lost, at the low end of confident estimates, several times as many men killed as the United States lost in Korea and Vietnam combined; its wounded dwarf the two wars together. At roughly 600 American dead a month in Vietnam, and under 1,000 a month in Korea, those were slow-burning national traumas. Russia has been losing soldiers killed at something closer to 5,000 to 10,000 a month — absorbing the entire human cost of Vietnam every two to three months, and of Korea faster still.
Both American figures are, of course, only a sliver of each war's true toll: at least 2.5 million people, most of them Korean civilians, died in Korea, and several million more across Indochina.
The other side of the ledger: Ukraine's losses
Russia's losses are the larger in absolute terms, but Ukraine has bled heavily too — and it has far fewer people to lose.
Western analysts put Ukrainian military casualties at roughly 500,000 to 600,000 — killed, wounded and missing — between February 2022 and December 2025, with 100,000 to 140,000 of them dead, according to CSIS; the Netherlands' military intelligence service and RFE/RL reached comparable totals in early 2026. That makes Russia's losses roughly two to two-and-a-half times Ukraine's — the dividend of fighting on the defensive in a war that rewards the defender. By The Economist's reckoning, the kill ratio in 2025 ran wider still, on the order of five Russian soldiers dead for every Ukrainian.
As with Russia, the dead are contested and the official numbers run low. President Volodymyr Zelensky put Ukraine's military dead at 55,000 in February 2026 — less than half the independent estimates, and a figure Kyiv has reason to keep modest, for morale at home and leverage abroad. The UALosses project, which outlets including Mediazona, Meduza and The Economist regard as reliable, had documented 96,821 Ukrainian fighters killed by name as of late June 2026, alongside a staggering 97,938 missing — many presumed dead, others held prisoner — for nearly 195,000 dead or missing in all. Some 11,600 Ukrainian soldiers are known to have been taken captive. The wounded number perhaps 300,000 to 400,000.
The war's civilian toll, meanwhile, falls overwhelmingly on Ukraine, the country being invaded: the United Nations had verified more than 16,000 Ukrainian civilians killed and some 47,000 injured by mid-2026, while cautioning that the true figures are considerably higher.
What makes Ukraine's losses more dangerous than the bare numbers suggest is arithmetic of a different kind. Russia entered the war with about 144 million people; Ukraine's population, even before more than six million fled abroad, was roughly a quarter of that — about 41 million. Set against those pre-war numbers, Ukraine's roughly 550,000 casualties amount to about 13 for every 1,000 people, against some 8 per 1,000 for Russia: so even as Russia loses far more men in absolute terms, Ukraine is losing a markedly larger share of itself. A casualty that costs Russia a fraction of a percent of its manpower pool costs Ukraine far more — which is why a country winning the exchange ratio on the battlefield has nonetheless slid into a deepening mobilization crisis, lowering its draft age and combing its cities for recruits. Russia can lose more men and feel it less. That asymmetry, more than any single battle, is the attritional logic the Kremlin is betting on.
A million casualties, almost no ground
What has all this bought? Strikingly little — and, lately, less than nothing.
Russia today holds roughly an eighth of Ukraine that it did not control before February 2022 — about 29,000 square miles, an area close to half of Illinois, according to the territorial mapping maintained by the Institute for the Study of War, the data set most analysts treat as authoritative. Add the Crimea and Donbas land Russia seized before the full-scale invasion, and the total comes to around a fifth of the country.
But almost all of that was taken in the war's opening months, and the price of each yard since has climbed relentlessly. Through 2025, Russian forces gained on the order of 2,000 square miles — an average of roughly 170 a month — while absorbing some 415,000 casualties, by ISW mapping and CSIS's loss estimates. That works out to a cost of about 200 casualties for every square mile taken.
In 2026 the arithmetic broke down. According to ISW data, Russia's net territorial position went into reverse: it lost ground across consecutive four-week windows through the spring — a net loss of about 26 square miles in April, 46 in early May, and 93 between early May and early June. (ISW revised its mapping methodology on May 2, 2026, refining how it calculates monthly area; it said the change did not alter its assessed trendlines.) Russian soldiers kept dying at a rate of tens of thousands a month, with Ukrainian officials reporting one of the deadliest stretches of the war. But the front was moving backward. The cost of a square mile, in other words, became impossible to calculate — because Russia was no longer buying any.
A lengthy conflict
Perhaps the starkest comparison is simply one of time. Russia has now been fighting in Ukraine for about 52 months — as long as the entire First World War, and longer than the Soviet Union spent defeating Nazi Germany (about 47 months) or the United States fought in the Second World War (about 45). Both of those wars were won outright in the span Russia has now spent failing to capture the Donbas.
In the same span of time, the Soviet Union had suffered some 8.7 million military dead — and won. The United States had suffered about 405,000 dead, liberated Western Europe, and accepted the surrender of two empires. But those American dead were spread across the entire globe — roughly 250,000 in the European and Mediterranean theaters, about 157,000 in the Pacific, the rest at sea and elsewhere. Russia's quarter-million to half-million dead have fallen along a single front about a thousand kilometers long: it has lost at least as many men grinding into eastern Ukraine as the United States lost defeating Germany across all of Western Europe and the Mediterranean. Russia, by contrast, holds an eighth of Ukraine it did not control in 2022 — ground its army, this spring, has started to give back.
A war Moscow expected to win in days has instead produced a casualty toll without precedent in eighty years — and, by the measure that matters most to the men sent into it, almost nothing to show for it.
A note on sources and figures
Casualty counts in any active war are contested, and all sides have incentives to inflate or suppress them; the figures here are presented as ranges where the underlying estimates diverge.
- Russian losses in Ukraine: Total casualties (~1.2 million) from the U.K. Ministry of Defense (Dec. 2025, ~1.17 million), Western officials reported by Bloomberg (Feb. 2026) and The Economist (May 2026, 1.1–1.5 million), with CSIS reaching a comparable figure; compiled estimates via Russia Matters. Confirmed-by-name deaths (~223,500, late May 2026) from BBC Russian / Mediazona and the statistical estimate (~352,000) from Mediazona / Meduza, both summarized in the casualties overview; higher death estimate (~500,000) from GCHQ. Monthly casualty rate (killed and wounded: ~35,000 in 2025 per CSIS; above 30,000 in early 2026 per U.K. military officials at the OSCE, April 2026); implied monthly deaths (~10,000–12,000) from Carnegie and Mediazona obituary tracking. Ukrainian official tallies, which run higher, are treated with caution and not used as primary figures.
- Ukrainian losses: Total casualties (500,000–600,000) and fatalities (100,000–140,000) through Dec. 2025 from CSIS, with similar totals from the Netherlands Military Intelligence and Security Service and RFE/RL (early 2026). Named dead (96,821) and missing (97,938) as of June 21, 2026 from the UALosses project. Ukraine's own official figure (55,000 killed, Feb. 2026) is treated as understated. Verified Ukrainian civilian casualties from the U.N. OHCHR (≈16,000 killed, ≈47,000 injured, mid-2026), described by the U.N. as a conservative floor. Per-capita rates use pre-war populations of about 144 million for Russia and about 41 million for Ukraine (Ukraine State Statistics Service, Jan. 2021, excluding occupied Crimea); Ukraine's effective wartime population is now far lower, with the U.N. estimating it has fallen by roughly 10 million since 2022.
- Territorial control and rate of advance: Institute for the Study of War mapping, as compiled by Russia Matters; figures reflect ISW's post–May 2, 2026 methodology revision. ISW relays the Ukrainian General Staff's daily casualty claims but does not publish an independent casualty estimate. The Pokrovsk advance rate (~70 m/day) is from CSIS. The "casualties per square mile" figures combine casualty estimates with territorial data: the Somme (~620,000 Allied casualties over ~90–100 sq mi gained) against Russia in 2025 (~415,000 casualties over ~1,900 sq mi). A clean per-metre casualty figure for Russia's Pokrovsk axis is not reliably available and is omitted. Front-line length (Ukraine's active line ~1,000 km, per Commander-in-Chief Oleksandr Syrskyi, Aug. 2024; the WWI Western Front ~700 km) and troop-density figures (~700 troops per mile in the most-contested Ukrainian sectors against ~10,000 per mile at the Somme) draw on the Dupuy Institute and contemporary analysis.
- Soviet WWII losses: G. F. Krivosheev, Soviet Casualties and Combat Losses in the Twentieth Century (~8.7 million military dead; ~15.2 million wounded), summarized here, with higher independent estimates noted.
- World War I: official national tallies (Germany ~2.0M, France ~1.35M, British Empire ~0.9M military dead); U.S. WWI dead (~116,500) and wounded (~204,000) via U.S. DoD/VA; the Somme via the National Army Museum and Verdun via Britannica.
- U.S. Civil War: the traditional ~620,000 count and J. David Hacker's census-based revision (~700,000–750,000); combat-vs-disease split and wounded via the American Battlefield Trust.
- U.S. and German WWII losses: National WWII Museum (~405,000 U.S. dead, ~671,000 wounded). By theater, roughly 250,000 U.S. dead in the European and Mediterranean theaters and about 157,000 in the Pacific (U.S. Department of Defense, via the WWII casualties overview). German military dead via Rüdiger Overmans. British military casualties for the stacked comparison — WWI ~886,000 killed and ~1.67 million wounded, WWII ~384,000 killed and ~376,000 wounded — via the U.K. National Archives and U.K. Parliament.
- U.S. Korea, Vietnam, Iraq and Afghanistan: U.S. National Archives and the Defense Casualty Analysis System (Vietnam: 58,220 dead, 153,372 hospitalized wounded; Korea: ~36,500 dead, ~103,000 wounded; Iraq: 4,431 dead, 31,994 wounded; Afghanistan: ~2,400 dead, ~20,700 wounded, per U.S. DoD); total Korean War toll (≥2.5 million) via Britannica.
- War durations: standard historical dating — Russia–Ukraine from Feb. 24, 2022 (ongoing, ~52 months); First World War (1914–1918, ~52 months); U.S. Civil War (1861–1865, ~48 months); the Soviet–German war (June 1941–May 1945, ~47 months); U.S. participation in World War II (Dec. 1941–Sept. 1945, ~45 months); the Korean War (1950–1953, ~37 months).
