The first North Korean soldiers were taken prisoner by Ukraine in early January, providing final confirmation of the Hermit Kingdom’s involvement in the ongoing Russian invasion of Ukraine following initial reports in late 2024. The participation of North Korean troops represents a dangerous escalation in what is already the largest European war since World War II, with potentially alarming implications for global security.
Pyongyang’s support for the Russian war effort began in late 2022 with the delivery of artillery shells. The list of armaments was subsequently expanded to include ballistic missiles. These supplies have helped Russia maintain the momentum of its invasion despite the country’s significantly depleted stores of munitions. With Moscow now also facing manpower shortages and reluctant to order a fresh round of mobilization, the arrival of North Korean troops helps relieve domestic pressure to recruit more Russians for the war.
While no official data is available, Ukrainian, US, and South Korean sources have estimated that North Korea has sent at least 11,000 soldiers to join Russia’s invasion. Some are believed to be drawn from highly trained elite units. Materials found on dead North Korean troops and battlefield accounts from Ukrainian forces indicate that the heavily indoctrinated North Koreans have been ordered to kill themselves if necessary to avoid being captured alive and taken prisoner.

Pyongyang has a very specific interest in sending troops to fight against Ukraine. While the deployment is unlikely to dramatically alter the battlefield situation in the Kremlin’s favor, it allows the North Koreans to acquire priceless combat experience, test weapons systems, gain access to Russian military technologies, and secure Moscow’s further assistance in countering UN sanctions.
North Korea currently boasts one of the world’s largest armies with around 1.3 million active soldiers. However, unlike Russia, the Korean People’s Army (KPA) has not been directly involved in any major wars for many years. This lack of battlefield experience is a source of considerable concern for North Korean dictator Kim Jong Un, who is anxious to counter South Korea’s more technologically advanced military.
Sending thousands of troops to fight in the Russian invasion of Ukraine provides the KPA with valuable insights into what is widely recognized as the most technologically advanced battlefield environment in the history of warfare. North Korean soldiers are now learning the realities of modern drone warfare first-hand. As a result, North Korea will be “more capable of waging war against its neighbors,” senior US officials have warned.

Ukrainians have been impressed by the skill and tenacity of the North Koreans they have encountered, including their ability to shoot down drones. “They are young, motivated, physically fit, brave, and good at using small arms. They are also disciplined. They have everything you need for a good infantryman,” Ukrainian army spokesman Lieutenant Colonel Yaroslav Chepurnyi told POLITICO.
North Korea is believed to receive significant financial and technological incentives for supplying Putin with soldiers. South Korean intelligence officials estimate that Moscow is paying Pyongyang $2000 per solder each month. While this money is no doubt welcome, the real prize is access to advanced Russian military tech. In exchange for troops, North Korea is believed to be receiving support from Moscow that will help upgrade its military, including the country’s anti-aircraft, submarine, and missile capabilities.
The Ukrainian front also serves as a valuable testing ground for North Korea, allowing the country to assess the effectiveness of the weapons it supplies to Russia. This will make it possible for Pyongyang to improve the quality of its own domestic arms industry and adapt future output to the realities of the modern battlefield. Meanwhile, the troops who survive their time on the Ukrainian front lines are expected to return home and become instructors, sharing their knowledge of modern warfare with colleagues.
At this point, North Korea’s participation in the Russian invasion of Ukraine looks to be less about supporting Putin’s imperial ambitions and more about upgrading Kim Jong Un’s war machine. In the short term, the presence of North Korean soldiers is allowing Russia to overcome mounting manpower shortages. But with Russia believed to be losing tens of thousands of troops each month, there is little chance that Pyongyang will be able to fully satisfy Moscow’s insatiable demand for additional manpower.
Looking ahead, the historically unprecedented appearance of North Korean soldiers on the battlefields of Europe could alter the security equation on the Korean peninsula and beyond. “For the first time in decades, the North Korean army is gaining real military experience,” commented Ukrainian military intelligence spokesman Andrii Yusov. “This is a global challenge. Not just for Ukraine and Europe, but for the entire world.”

Two soldiers, though wounded, survived and were transported to Kyiv, where they are now communicating with the Security Service of Ukraine, Zelenskyy said. This was not an easy task: Russian forces and other North Korean military personnel usually execute their wounded to erase any evidence of North Koreas involvement in the war against Ukraine, he said. I am grateful to the soldiers of Tactical Group No. 84 of the Special Operations Forces of the Armed Forces of Ukraine, as well as our paratroopers, who captured these two individuals.
