In an exclusive interview with the BBC, former Ukrainian commander‑in‑chief Oleksandr Syrskyi – who was removed from his post in the summer of 2024 – argued that Russia’s capacity to launch large‑scale offensives has been fundamentally weakened.
Claims about Russian losses
Syrskyi asserted that Moscow’s overall losses in the war are six times higher than Ukraine’s, and up to eleven times higher if only fatalities are counted. He referenced two external estimates:
- UK intelligence estimates roughly half a million Russian soldiers have been killed since the invasion began in 2022.
- CSIS estimates Ukrainian casualties at up to 150,000 killed by June 2026.
Both figures are unverified, as neither side publishes official casualty numbers.
Front‑line stabilisation
The general highlighted that, in the first six months of 2026, Russian forces managed to seize only 61 sq km of territory. He described this limited gain as an indication that the front line has been stabilised and that Russia is no longer able to achieve significant advances.
Technological factors
Syrskyi linked the attrition gap to Ukraine’s increasing use of technology, especially unmanned systems. He claimed that drones now account for 80 % of Russian losses, and that Ukraine’s Unmanned Systems Forces – created under his command – have enabled deep strikes up to 2,000 km behind enemy lines.
Context of the general’s dismissal
Oleksandr Syrskyi was appointed commander‑in‑chief in 2024 after gaining recognition for defending Kyiv in 2022 and leading a successful counter‑offensive near Kharkiv. His removal followed a public dispute with Defence Minister Mykhailo Fedorov over procurement priorities, with President Volodymyr Zelensky ultimately dismissing both men amid street protests.
Uncertainty and verification
While Syrskyi’s statements provide a vivid picture of a war‑wearied Russian military, the specific casualty numbers and the exact impact of drones remain difficult to verify independently. The Institute for the Study of War (ISW) has noted a trend of Russia losing more territory than it gains in recent months, but detailed data are limited.
Bottom line: According to a former Ukrainian top commander, Russia’s offensive capability appears to be severely degraded, driven by high personnel losses and Ukraine’s growing technological edge, though the precise scale of these effects cannot be confirmed with open‑source data.
