Ukraine war briefing: Nearly 2 million military casualties to date, study finds, with Russia bearing brunt of losses
A US think‑tank estimates that military casualties in the Russia‑Ukraine conflict will near two million by spring 2026, with Russian forces suffering the greatest losses.

The Russia‑Ukraine war is on track to surpass two million military casualties, according to a recent analysis by the Center for Strategic and International Studies (CSIS). The think‑tank’s model projects a combined total of 1.8 million to 2 million killed, wounded or missing by the spring of 2026, with Russian forces accounting for the bulk of the toll.
Scale of military losses
CSIS estimates that Russia has suffered roughly 325,000 deaths out of an overall 1.2 million Russian‑Ukrainian casualties since the invasion began in February 2022. Ukrainian forces are believed to have incurred between 500,000 and 600,000 casualties, including 100,000‑140,000 fatalities, over the same period. These figures are based on open‑source data, battlefield reports and demographic modeling, and they exceed official Russian Ministry of Defence numbers, which last reported 5,937 killed in September 2022.
Ukrainian President Volodymyr Zelenskyy has previously told NBC that Ukraine lost close to 46,000 troops, a number analysts consider a low estimate. Independent outlets such as the BBC’s Russian service and Mediazona, which track death notices and other public records, have identified more than 163,000 Russian soldiers killed, acknowledging that the true count is likely higher.
Human cost beyond the battlefield
United Nations monitors have verified almost 15,000 civilian deaths since the war’s outset, though they caution that the real figure is considerably larger. The civilian toll includes the recent drone strike on a passenger train in the Kharkiv region, which killed five people and injured dozens. Zelenskyy described the attack as terrorism, noting that the train carried over 200 passengers, including 18 in the carriage that was hit.
The train bombing was part of a broader wave of Russian drone and missile attacks that left ten dead nationwide and wounded many more, among them two children and a pregnant woman. In Odesa, a drone strike killed three and wounded 32, while also damaging a major power facility operated by private energy firm DTEK. Energy Minister Denys Shmyhal warned that 710,000 Kyiv residents remain without electricity and heating, a situation that could become lethal as winter deepens.
Additional casualties have been reported in Donetsk, Zaporizhzhia and Kherson, underscoring the war’s spread across multiple fronts and its impact on civilian infrastructure.
Technology, diplomacy and the Starlink controversy
Poland’s foreign minister and deputy prime minister, Radosław Sikorski, has publicly urged Elon Musk to block Russian access to the Starlink satellite internet service, alleging that the Russian military uses the network to guide drone attacks deep inside Ukraine. The request follows a report from the US‑based Institute for the Study of War that linked Starlink terminals to Russian targeting capabilities.
Musk has denied any direct sales of Starlink terminals to Russia, stating that any equipment reaching Russian forces has likely been obtained through third‑party intermediaries rather than an official contract. Ukrainian intelligence agencies have corroborated this claim, noting that Russian units have acquired terminals via illicit channels.
What lies ahead
The CSIS projection suggests that total military casualties could reach the two‑million mark by early 2026, a grim milestone that highlights the war’s enduring intensity. Diplomatic efforts continue, but each new Russian strike, especially those that target civilian infrastructure, threatens to erode any progress toward a negotiated settlement.
International scrutiny over the use of commercial technology in the conflict is also likely to intensify. If pressure on companies like SpaceX leads to stricter controls on satellite services, it could alter the tactical calculus for the Russian military. Conversely, continued access to high‑speed communications may enable Ukraine to better coordinate its defence and maintain resilience in the face of relentless attacks.
For now, the human cost remains the most tangible measure of the war’s toll, and the world watches as both sides grapple with mounting losses, dwindling resources, and the looming prospect of a protracted stalemate.
Why it matters
Understanding the scale of casualties and the role of technology in the conflict informs policy decisions and humanitarian responses as the war approaches a potential two‑million‑casualty threshold.
Key points
- CSIS estimates nearly 2 million military casualties by spring 2026, with Russian forces suffering the greatest losses
- Ukrainian civilian death toll is verified at ~15,000 but likely higher, with recent train bombing killing five
- Poland urges Elon Musk to cut Russian access to Starlink after reports of its use in drone targeting
- Energy infrastructure remains vulnerable, leaving hundreds of thousands without heat and power in winter
- Diplomatic talks continue despite escalating attacks, making a negotiated end increasingly difficult
Frequently asked questions
How many military casualties have been reported in the Ukraine war so far?
CSIS estimates about 1.2 million Russian‑Ukrainian casualties to date, with total deaths around 425,000‑465,000 and the overall figure expected to approach two million by early 2026.
What was the recent train attack in Kharkiv?
A Russian drone struck a passenger train near a village in the Kharkiv region, killing five people and injuring dozens; the train carried over 200 passengers, including 18 in the damaged carriage.
Why is Poland calling on Elon Musk to block Starlink?
Polish officials claim Russian forces are using Starlink terminals to guide drone strikes, and they want the service disabled for Russia to reduce its targeting capability.
Has Elon Musk sold Starlink equipment to Russia?
Musk has denied any direct sales to Russia; Ukrainian intelligence says any terminals in Russian hands were obtained through third‑party channels, not official contracts.
What impact are the attacks having on Ukrainian civilians?
Beyond the death toll, attacks have damaged power facilities, left hundreds of thousands without electricity and heating, and caused injuries to children and pregnant women, worsening humanitarian conditions.
