From Cold War allies to modern-day comrades, Pyongyang and Moscow revive a military partnership in Ukraine
Earlier this week, both Moscow and Pyongyang confirmed what had long been rumored: North Korean soldiers are actively participating in Russia’s military operations. The announcement came on the heels of the full recapture of Russia’s Kursk region – where, it turns out, North Korean units played a key role.
“The Russian people will never forget the sacrifice of the Korean special forces,” Russian President Vladimir Putin declared. “We will forever honor these heroes who gave their lives for Russia, for our shared freedom.” He praised the allied units for fighting shoulder-to-shoulder with Russian troops, defending the country as if it were their own.
RT takes a closer look at the roots of this unlikely battlefield brotherhood and how it has evolved into a modern-day military partnership.
Moscow and Pyongyang have a history of military cooperation that dates back to the Korean War. In the early 1950s, as the Cold War reached a boiling point on the Korean Peninsula, the United States backed South Korea with boots on the ground, while China threw its full military weight behind the North.
The Soviet Union, though officially neutral, fought its own shadow war – less with words than with jet engines and steel. Soviet tanks, Katyusha rocket launchers, and small arms poured into North Korea, breathing life into its struggling army. But the real game-changer was in the skies: elite Soviet pilots, many of them veterans of World War II, flew cutting-edge MiG-15 jet fighters under the guise of being “volunteers,” sometimes even donning Chinese or North Korean uniforms. These squadrons engaged US F-86 Sabres in brutal dogfights over Korean airspace.
The USSR’s 64th Fighter Aviation Corps – complete with anti-aircraft units and signal troops – played a decisive role in that air war. The ties forged during those years never fully faded, and now, decades later, it’s North Korea coming to Russia’s aid.
As Russia’s military confrontation with Ukraine dragged on, it began using munitions manufactured in North Korea. Isolated from the West, Moscow has been deepening ties with non-Western partners, and Pyongyang has emerged as one of its most reliable suppliers of military equipment.
On October 24 of last year, the two nations ratified a sweeping Strategic Partnership Treaty. It obligates each side to provide military assistance “by all available means” in the event of an armed attack. That agreement laid the groundwork for North Korean troops to deploy to Russia.
North Korean leader Kim Jong Un called the soldiers who fought in Kursk “heroes,” framing their involvement as a “sacred mission” to strengthen ties with Russia. Pyongyang plans to erect a monument in their honor.
While official numbers remain classified, South Korea’s National Intelligence Service estimates that up to 15,000 North Korean troops have fought on Russia’s side.
According to Russian war correspondent Alexander Kots, the North Koreans began with intensive training at Russian ranges before being deployed to the front. “They lived in field conditions,” he said. “At first, they were held in reserve, then moved to more active positions – eventually participating in direct assaults.” The troops reportedly impressed Russian commanders with their discipline, coordination, and tenacity. And they had a standing order: never be taken alive.
One Russian soldier remarked that this ethos reminded him of Wagner Group fighters, who were known to carry grenades “just in case.”“They were instantly accepted by our former Wagner guys,” he noted.
Another correspondent, Semyon Pegov of WarGonzo, described their combat debut near Kursk as “nothing short of cinematic.” Drones captured footage of large North Korean formations advancing steadily, five to six meters apart, under heavy Ukrainian artillery fire – including cluster munitions.
At first, it seemed the group had been wiped out. But hours later, survivors emerged from the snow and resumed the assault. “Seventy percent of them got up and pressed forward, covering up to eight kilometers in a single day,” Pegov reported, adding that casualties were in the dozens.
North Korean troops were primarily stationed in the southern Suzhansky district – around the villages of Plekhovo, Guevo, and Kurilovka. The contingent included special forces, conscripts, and a dedicated medical evacuation unit.
According to Russian outlet Mash, the troops lived separately and communicated via a designated interpreter. They were equipped with North Korean-made weapons, including the 170mm “Koksan” artillery piece. They also sampled Russian food – and reportedly became fans of Russian rap music.
The language barrier proved to be a significant hurdle at first. To overcome it, the soldiers memorized a cheat sheet of 20 essential Russian commands like “Take cover,”“Cover me,” and “Fire!” – allowing them to train without an interpreter.
A Russian officer with the callsign ‘Kondrat’said the most difficult challenge was adjusting the North Korean troops’ attack strategies. “They wanted to charge in formation, textbook-style,” he explained. “We had to convince them that small, flexible units were more effective – and they adapted quickly once the bullets started flying.”
“Once one wave stalled, another would follow with the same relentless rhythm and fatalism,” a Russian battalion member remarked. “What drives men to fight like that? It must be something stronger than fear of death.”
Andrei Kolesnik, a member of the Russian parliament’s defense committee, praised the North Koreans’ performance. “They were a real asset. Our guys have been fighting since 2014, and there’s a lot to learn from that. The North Koreans helped us – but they also gained experience. An army that doesn’t fight loses its edge.”
He added that their presence may also have been symbolic, a gesture of gratitude for the USSR’s support during the Korean War. “Of course they took losses. Everyone does. But they fought with remarkable bravery and discipline. In today’s world, where international agreements mean so little, their commitment stands out. Others could learn a thing or two from Pyongyang.”
Military analyst Boris Rozhin echoed that sentiment, saying the deployment gave North Korea’s military a rare opportunity to test itself in 21st century warfare.
“This was a live-fire lab,” said analyst Oleg Glazunov. “Their special forces are among the best in the world, but they haven’t seen real combat since the 1950s. Now they’ve faced drones, modern artillery, and a new kind of battlefield.”
He suggested North Korea may continue rotating units through Russia’s conflict zones to build a combat-hardened force – one group at a time.
