North Korea has deployed troops, weapons and now, according to a Ukrainian intelligence official, a missile unit to support Russia’s war against Ukraine, marking Pyongyang’s most significant involvement in a war since the 1950s.
Here is what is known about the growing military ties:
THE LATEST REPORTS
A North Korean missile unit has begun deploying to western Russia and could be equipped with up to 120 ballistic missiles and six launchers for attacks on Ukraine, an official at Ukraine’s GUR military intelligence agency said.
The unit comprises about 90 North Korean personnel and is expected to be based in Russia’s Voronezh region, the official said. The United States is aware of the North Korean deployment, a source familiar with the issue told Reuters.
Forty North Korean missiles have already been supplied, at least two of which were launched at Ukraine last week during a deadly strike, the Ukrainian official said.
Ukrainian President Volodymyr Zelenskyy said in July that Russia wanted to bring in 30,000 North Korean troops and was preparing facilities in Voronezh to receive them.
Reuters could not independently verify that statement.
HOW MANY NORTH KOREAN TROOPS WERE SENT TO RUSSIA IN 2024?
North Korea sent around 14,000 to 15,000 soldiers to Russia’s Kursk region, according to Ukrainian and South Korean estimates, helping Moscow’s forces repel a surprise Ukrainian ground incursion.
Russia and North Korea confirmed in April 2025 that North Korean troops had fought Ukrainian forces in Kursk.
Russia’s top military commander praised their role after Moscow said it had retaken Kursk territory, while Pyongyang said the deployment was ordered by leader Kim Jong Un.
The Ukrainian official said this month that around 9,500 North Korean troops remained in Kursk, but were not directly involved in operations against Ukraine.
WHAT OTHER PERSONNEL HAS NORTH KOREA SAID IT WILL PROVIDE?
In June 2025, Russian Security Council Secretary Sergei Shoigu said North Korea would send 1,000 sappers and 5,000 military construction workers to Kursk to clear mines and help rebuild infrastructure damaged in the fighting.
That same month, South Korean lawmakers, citing a briefing by the National Intelligence Service, said that North Korea appeared to have begun recruiting personnel for an additional deployment to Russia, while continuing to supply Russia with artillery ammunition and missiles in exchange for economic cooperation and technical assistance.
It remains unclear how many engineers, deminers or additional troops have arrived in Russia, or whether they have been used in combat roles.
WHAT WEAPONS HAS NORTH KOREA PROVIDED?
North Korea has supplied Russia with millions of artillery and mortar rounds, ballistic missiles, long-range artillery and multiple-launch rocket systems, according to Ukrainian and independent assessments.
A Reuters analysis with the British-based Open Source Centre found four Russian-flagged cargo ships made 64 voyages to North Korea’s Rajin port between September 2023 and March 2025, transporting nearly 16,000 containers of ammunition to Russian ports.
Ukrainian officials said North Korea was supplying about half of the munitions Russia needed on the front lines.
Ukraine’s military intelligence agency said that North Korea had delivered 4 million artillery shells since mid-2023, excluding mortar rounds. It said North Korea had supplied 148 KN-23 and KN-24 ballistic missiles by the start of 2025.
WHY IS NORTH KOREA HELPING RUSSIA?
Russian President Vladimir Putin and North Korean leader Kim signed a comprehensive strategic partnership treaty during Putin’s June 2024 visit to Pyongyang. The pact includes a mutual assistance provision if either country faces external aggression.
North Korea has cast its deployment as assistance to a treaty partner. Kim said in May 2025 that participation in the war was justified as an exercise of North Korea’s sovereign rights in defense of a “brother nation.”
Analysts say Pyongyang stands to gain hard currency, oil and other economic support, as well as access to Russian military technology and battlefield experience for its forces and weapons.
North Korean soldiers have gained combat exposure to drones, electronic warfare, artillery coordination and modern battlefield tactics, while its missile and ammunition makers have been able to assess their equipment in wartime conditions.
THE INTERNATIONAL REACTION
The United States and its allies have said the troop deployments and arms transfers violate U.N. Security Council resolutions on North Korea.
Pyongyang has been subject to U.N. sanctions since 2006 over its nuclear weapons and ballistic missile programs. The sanctions prohibit countries from hosting North Korean trainers, advisers or other officials for military, paramilitary or police training.
Washington imposed additional sanctions in December 2024 on North Korean and Russian entities connected to Pyongyang’s military and financial support for Moscow. South Korea also blacklisted individuals and entities linked to illicit military cooperation between the two countries.
NATO has said Russia’s growing military and economic ties with North Korea, China and Iran pose a threat beyond Europe, extending to the Indo-Pacific and North America.

Executive Summary
North Korea has deployed a missile unit to western Russia, with reports indicating it may be equipped with up to 120 ballistic missiles and six launchers intended for attacks on Ukraine. This deployment represents Pyongyang’s most significant involvement in a war since the 1950s. Ukrainian officials indicated that Russia sought to bring in 30,000 North Korean troops and prepared facilities in Voronezh to receive them.
In 2024, North Korea sent approximately 14,000 to 15,000 soldiers to Russia's Kursk region, which contributed to Moscow repelling a Ukrainian ground incursion; Russia and North Korea confirmed fighting occurred in Kursk in April 2025. Furthermore, North Korea has supplied Russia with millions of artillery rounds, ballistic missiles, and various rocket systems, including 4 million artillery shells since mid-2023. This support is framed by Pyongyang as an exercise of sovereign rights for a "brother nation," while analysts suggest the exchange involves North Korea gaining hard currency, technology, and battlefield experience.
The international community, including the United States and its allies, has expressed concern that these troop deployments and arms transfers violate United Nations Security Council resolutions regarding North Korea’s nuclear programs, leading to additional sanctions. NATO also views Russia's growing military and economic ties with North Korea as an extension of threat beyond Europe.
Full Take
The narrative illustrates a dynamic where military action is framed through strategic realignment, creating complex accountability gaps between actors. The deployment of missile units suggests a tangible mechanism for exerting influence, moving beyond mere political signaling to operational integration within the conflict zone. The flow of personnel and materiel—soldiers alongside specialized engineers and munitions—indicates that the relationship transcends simple diplomatic arrangement; it involves the practical transfer of military know-how and combat exposure, as evidenced by the training received by North Korean forces in drone warfare and electronic countermeasures.
The core pattern observed is the transactional nature of this relationship: resource supply (missiles, ammunition) in exchange for strategic security and access to advanced military experience. This dynamic allows Pyongyang to position itself as a necessary partner rather than an adversary, leveraging perceived sovereign rights to justify involvement while simultaneously securing economic and technological benefits. The ambiguity regarding the direct combat roles of all deployed personnel raises critical questions about command structures and ultimate responsibility for battlefield outcomes.
This situation challenges traditional understandings of international sanctions enforcement; when state actors engage in strategic partnerships that blur lines between assistance and coercion, the effectiveness of regulatory frameworks is tested. The external reaction from the U.S. and NATO highlights a systemic tension between national security interests and the established international norms governing North Korea’s status. What is being masked here is the ongoing assessment by all parties on whether these tactical military engagements constitute genuine sovereign decision-making or are merely instruments of broader geopolitical maneuvering benefiting external powers.
Bridge questions: How can international bodies establish verifiable metrics for assessing indirect material support provided within these strategic pacts? What are the long-term societal costs borne by populations affected by this militarized relationship, and who is currently bearing those costs? If established military cooperation exists between non-state entities or proxy forces supported through these channels, how should accountability be assigned across state lines?
