North Korean soldiers deployed to support Russian forces in the war against Ukraine have been described by Ukrainian fighters and intelligence sources as deeply indoctrinated, highly disciplined, and prepared to die rather than face capture. Their involvement, which began in late 2024, has added a stark international dimension to the conflict, particularly in Russia’s Kursk region.
### Deployment and Strategic Context
Under a mutual defense pact signed between Moscow and Pyongyang, North Korea sent approximately 11,000 to 14,000 troops — primarily combat soldiers from elite units, along with some engineers — to Russia starting in late 2024. Many arrived in Russian uniforms with falsified identities, often posing as members of ethnic minorities. They underwent training in eastern Russia before being committed to frontline operations in Kursk Oblast, where Ukrainian forces had launched a significant incursion.
The deployment has proven mutually beneficial. Russia gains additional manpower to offset its own losses, while North Korea secures combat experience for its forces, financial compensation, and strengthened military-political ties with Moscow. By early 2026, thousands of North Korean troops remained active in the region, participating in artillery strikes, reconnaissance, and later demining and reconstruction efforts even after major Ukrainian advances were repelled.
### Indoctrination and Battlefield Conduct
Ukrainian special forces and captured North Korean soldiers have painted a picture of troops shaped by lifelong state propaganda. Many were reportedly told they would be fighting “South Korean” forces aiding Ukraine, and they carried ideological memos emphasizing loyalty to Kim Jong Un above all else.
A recurring theme is their refusal to surrender. Multiple accounts detail North Korean soldiers detonating grenades or taking their own lives when capture seemed imminent, viewing surrender as treason that could endanger their families back home. In one early incident, a wounded soldier blew himself up as Ukrainian troops approached. Captured soldiers, such as Paek and Ri in January 2025, described instructions to self-destruct if necessary and revealed the presence of North Korean security officers monitoring units.
Ukrainian commanders have referred to them as “brainwashed,” noting their resilience under fire and willingness to absorb heavy losses. While they demonstrated strong marksmanship and discipline from long service terms, they often struggled with modern elements of the battlefield, such as widespread drone usage and combined-arms tactics. Some reports highlight “human wave” assaults with limited Russian support, contributing to high casualty rates.
### Heavy Casualties and Ongoing Presence
South Korean and Western intelligence estimates place North Korean casualties in the thousands, with figures exceeding 6,000 killed or wounded by mid-2025 in Kursk operations alone. Ukrainian sources have reported even higher losses in specific assaults. Despite this, North Korea has honored fallen soldiers in public ceremonies, with Kim Jong Un praising those who chose death over capture.
As of early 2026, around 8,000 to 11,000 North Korean personnel were still stationed in Kursk, shifting roles toward artillery support, border strikes, and post-combat tasks like demining. Russia has awarded medals to surviving troops and plans monuments to commemorate their “combat brotherhood” with North Korean forces.
### Broader Implications
The involvement of North Korean troops underscores the war’s evolution into a broader confrontation involving authoritarian alliances. Evidence from POW interrogations, battlefield diaries, and drone footage has provided rare insights into the closed world of the North Korean military. For Pyongyang’s soldiers — many young and minimally briefed on the true nature of the conflict — the experience has been one of extreme hardship, ideological fervor, and devastating losses.
As fighting continues along the border areas, the presence of these troops remains a testament to the lengths both Russia and North Korea are willing to go in pursuit of their strategic goals.
