British Defence Intelligence Update Ukraine 15 August 2025

Latest from the British Defence Intelligence.

  • ​​It has been reported that Russian President Putin has reiterated longstanding maximalist demands regarding Russia’s illegal invasion of Ukraine, including for the withdrawal of Ukrainian forces from the four internationally-recognised Ukrainian oblasts of Luhansk, Donetsk, Zaporizhia, and Kherson.
  • Based on the rate of Russia’s incremental battlefield advances so far in 2025, it would take Russian forces approximately 4.4 more years to gain 100 per cent of the four Ukrainian oblasts territory.
  • Based on Russia’s average daily casualty rate in 2025 so far, as reported by Ukrainian General Staff, 4.4 more years of war would lead to approximately 1,930,000 further Russian casualties (killed and wounded). This is in addition to the approximately 1,060,000 casualties Russia has already likely sustained since launching the full-scale invasion of Ukraine in 2022, including around 250,000 killed or missing (presumed dead).
  • Russia announced the illegal and erroneous annexation of the four internationally-recognised Ukrainian oblasts, including those areas under Ukrainian control, in September 2022, contradicting Russia’s own formal recognition of Ukraine’s independence and sovereignty following the collapse of the Soviet Union.
