Putin nightmare as quagmire sees Russia suffering ‘400 casualties per kilometre’

Russia is reportedly struggling to replace mounting battlefield losses in Ukraine, with Ukrainian intelligence claiming the Kremlin’s recruitment drive is failing to keep pace with the growing casualty rate. According to Ukraine’s Foreign Intelligence Service (SZRU), the Russian Ministry of Defence had recruited around 195,000 contract soldiers by early July 2026—less than half of its annual target of 409,000 personnel.

The agency claimed Russia’s recruitment rate has slowed from around 1,200 people a day in 2024 to roughly 1,090 recruits a day by mid-2026, leaving Moscow on course to miss its yearly goal. SZRU also alleged that rising battlefield losses have forced Russian authorities to relax medical and administrative requirements for new recruits while increasing efforts to recruit students, foreign nationals and residents of Russian-occupied areas of Ukraine. Ukraine’s Commander-in-Chief, General Oleksandr Syrskyi, claimed on July 14 that Russian forces are now suffering more than 400 casualties for every square kilometre they capture in the Donetsk region.

If accurate, the figure would highlight the high cost Russia is paying for incremental territorial gains as fighting continues in eastern Ukraine.

The Institute for the Study of War (ISW), a US-based think tank, has also reported that Russian losses remain exceptionally high. However, it uses a different methodology to calculate casualty rates.

ISW previously estimated that Russian forces sustained around 1,298 casualties for every square kilometre seized or infiltrated during June 2026, compared with an average of 68 casualties per square kilometre captured during the same month a year earlier across the wider theatre of war.

The organisation said the difference between its estimate and Syrskyi’s assessment stems from the fact that its calculations cover the entire frontline, while Syrskyi’s figures relate specifically to Donetsk Oblast.

The ISW added that it cannot independently verify casualty figures for individual Ukrainian regions.

The think tank also noted it is unclear whether Syrskyi’s calculation includes Russian infiltration attacks that failed to seize territory or how recently liberated areas near Lyman affect the overall figures.

Despite those differences, the ISW said Syrskyi’s assessment supports a broader trend showing Russian forces are sustaining significant personnel losses for relatively small battlefield gains.

According to the think tank, Russia’s casualty rate has exceeded its recruitment rate since March 2026, suggesting the Kremlin could face increasing difficulty replacing frontline losses without introducing a broader compulsory mobilisation.
