Ukrainian special operations forces have given an insight into the brutal, near-suicidal tactics of the North Koreans they have faced in intense fighting in the Russian border region of Kursk.

North Korean troops seem to temporarily withdraw from one section of front in Kursk Oblast, military says ・Russia claims to capture Velyka Novosilka, Ukraine admits partial retreat but says battles ongoing ・Russia intensifies attacks near Pokrovsk,

Ukrainian forces described a different kind of enemy, fighting with unfamiliar tactics and little option to retreat.

All North Korean recruits are taught a song that includes a verse about saving their last bullet for themselves to avoid capture, one former soldier told NBC News.
