UK Defence Intelligence has analysed that as of January 2025, North Korea has already lost about 4,000 military personnel in the Russian-Ukrainian war who took part in the fighting in Russiaʼs Kursk Oblast.

The losses represent over a third of the approximately 11,000 North Korean troops deployed in Kursk Oblast. The high casualty rate has severely degraded the ability of North Korean forces to conduct offensive operations in support of Russia's attempts to push Ukrainian forces out of Kursk Oblast.
