America And South Korea Prepare For A North Korean Army Hardened In Ukraine
North Korea Fires Again As America Prepares For A New Kind Of War
Kim Jong Un’s Army Has Changed — And 18,000 Troops Are Preparing For What Comes Next
The allies will mobilise around 18,000 South Korean troops for a major 11-day exercise—days after Pyongyang resumed ballistic missile launches and amid warnings that its soldiers are returning from Russia with real battlefield experience.
The United States and South Korea are preparing for one of their largest annual military exercises as the threat posed by North Korea enters a more dangerous phase.
Ulchi Freedom Shield 2026 will run from 17 to 27 August, combining command-post simulations with live, virtual and field-based training across multiple military domains.
Around 18,000 South Korean personnel will participate, according to Seoul’s Joint Chiefs of Staff. The number is broadly consistent with previous years, but the threats being rehearsed have changed significantly.
This year’s scenarios will account for drones, electronic warfare, GPS disruption and cyberattacks—capabilities that have become central to modern conflicts.
Crucially, the allies are also preparing for a North Korean military that has gained direct combat experience through its involvement in Russia’s war against Ukraine.
Ukraine Has Changed The North Korean Threat
North Korea is no longer merely studying modern warfare from a distance.
Its soldiers have fought alongside Russian forces, while North Korean missiles, artillery ammunition and other weapons have been deployed on the battlefield.
US Army Colonel Ryan Donald, public affairs director for the Combined Forces Command, United Nations Command and US Forces Korea, said the experience acquired in Ukraine had altered North Korea’s military capabilities.
“DPRK soldiers have deployed and fought in Ukraine, and they’ve taken those lessons they’ve learned there and brought them back to North Korea,” Donald said.
“That changes the DPRK capability, and our training accounts for that threat.”
The statement confirms that North Korea’s involvement in Ukraine is now directly influencing American and South Korean defence planning.
The concern is not simply that Pyongyang has gained combat experience. North Korean forces have been exposed to drone warfare, electronic countermeasures, massed artillery operations and the difficulties of fighting under constant aerial surveillance.
Lessons learned in Russia could now be incorporated into North Korean training, doctrine and weapons development.
What The Exercises Will Cover
Ulchi Freedom Shield will test the ability of American and South Korean forces to respond to a broad attack against the Korean Peninsula.
The programme will include:
Counter-drone operations
Responses to GPS jamming and disruption
Cyber-defence exercises
Electronic warfare scenarios
Command-and-control simulations
Field training involving multiple branches of the armed forces
South Korean government emergency-readiness drills
The allies insist the exercise is defensive and is focused exclusively on threats affecting South Korea and the Korean Peninsula.
However, North Korea has consistently described US–South Korean exercises as rehearsals for invasion. Pyongyang has frequently answered previous drills with missile launches, military statements or weapons demonstrations.
North Korea Has Resumed Ballistic Missile Tests
The exercise announcement comes only days after North Korea fired a short-range ballistic missile towards the sea off its eastern coast.
The 6 August launch was Pyongyang’s first ballistic missile test in more than 40 days, although North Korea had continued experimenting with other tactical and missile-related weapons during 2026.
South Korea, the United States and Japan condemned the launch, which breached United Nations Security Council resolutions prohibiting North Korean ballistic missile activity.
There is no confirmed evidence that the test was ordered specifically in response to Ulchi Freedom Shield. However, its timing has reinforced concerns that another cycle of military exercises and North Korean retaliation could be beginning.
North Korea has continued expanding its nuclear weapons, ballistic missiles, cruise missiles, artillery and conventional forces despite international sanctions.
The country has also rewritten its constitution to remove references to peaceful reunification with South Korea and formally present itself as a nuclear-armed state.
That shift suggests Kim Jong Un’s government increasingly views the South as a permanent hostile neighbour rather than a population intended for eventual reunification.
Russia Has Given Kim Jong Un Something Sanctions Could Not Stop
The alliance between North Korea and Russia has transformed Pyongyang’s strategic position.
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.
An estimated 14,000 North Korean soldiers were previously sent to Russia’s Kursk region. Ukrainian President Volodymyr Zelenskyy has since claimed that a decision has been made to deploy between 30,000 and 50,000 additional North Korean personnel, although he did not disclose the source of that figure.
Ukraine also says a North Korean missile unit has begun deploying to western Russia and could operate as many as 120 ballistic missiles with six launchers.
In return, Pyongyang may receive money, energy, military technology and assistance developing weapons that North Korea struggled to perfect in isolation.
The relationship also provides something that cannot easily be obtained through weapons testing: experience of how soldiers, missiles and communications systems perform during a real war.
Why This Matters Beyond Korea
A more capable North Korean military would affect far more than the immediate balance between North and South Korea.
Approximately 28,500 American military personnel are permanently stationed in South Korea. Any major conflict could rapidly involve the United States, Japan and potentially China.
North Korea’s nuclear arsenal adds another layer of danger. Even a conventional confrontation could escalate if either side believed that strategic weapons were being prepared for use.
The growing relationship between Moscow and Pyongyang also connects the security of Europe and East Asia more closely than before.
Weapons supplied by North Korea are being used against Ukraine. The experience and technology obtained in return could later strengthen the forces positioned against South Korea, Japan and the United States.
Ukraine is therefore becoming a proving ground for capabilities that could eventually reappear on the Korean Peninsula.
What Happens Next?
Ulchi Freedom Shield is scheduled to begin on 17 August and continue for 11 days.
North Korea has not yet announced a formal response. Based on previous years, Pyongyang could issue threats, conduct further missile launches or hold its own military exercises while the allied drills are underway.
The most important question will be whether North Korea uses the coming weeks to demonstrate capabilities refined through its relationship with Russia.
For Washington and Seoul, the exercise is intended to show that the alliance is adapting before those lessons can produce a decisive North Korean advantage.
The number of troops may be similar to previous years. The military they are preparing to confront is not.
