Location of the ROK Army 25th Division and Summary of the DMZ Mine Explosion Incident Involving the Biryong Unit
1. Overview and History of the ROK Army 25th Infantry Division
The ROK Army 25th Infantry Division is a historic infantry division that firmly defends the western front of the Republic of Korea, known by the nickname “Biryong Unit” (Ascending Dragon Unit). Established on April 21, 1953, just before the armistice of the Korean War, the unit was born in a critical period to protect the nation. For decades since its establishment, it has played a crucial role in defending the capital, Seoul, from the north while being responsible for the border regions in northern Gyeonggi Province. The unit’s official greeting is “Unity,” reflecting the determination of all soldiers to join forces to complete their missions. As a frontline combat division distinct from typical rear-area units, it always maintains a practical combat posture. With a long history, it boasts numerous achievements and traditions, and even now, it is dedicated to its guard duties, enduring both cold and heat.
Unit members devote all their energy to daily training and operational preparation to maintain a thorough state of readiness, even in harsh natural environments. Hearing stories from acquaintances who have served in the military, one can easily imagine how tense and grueling service in a border region division can be.
The 25th Division, established in 1953, is a core frontline Army division known as the Biryong Unit, responsible for defending the western front.
2. Location of the 25th Division and Characteristics of Major Garrison Areas
When many people search for the location of the 25th Division, the first fact they encounter is that the division headquarters is located in Nam-myeon, Yangju City, Gyeonggi Province. However, a large-scale infantry division does not operate from a single garrison; it is deployed across multiple areas. In fact, the main operational areas under the 25th Division’s jurisdiction broadly include not only Yangju City but also Paju City and Yeoncheon County. When conducting military operations or tactical training, these entire border regions are treated as one vast operational radius, moving organically. Therefore, defining the location of the 25th Division solely as Yangju makes it difficult to fully understand the extensive scope of operations the unit performs.
Given its responsibility for security in the northwest of the capital region, it is paramount for unit members to fully grasp the topographical characteristics. If you drive on roads in the Yangju or Paju areas during vacation seasons or weekends, you may naturally encounter military vehicles or soldiers. It is always important to remember that the frontline of national defense is being guarded very close to our daily lives.
While the 25th Division headquarters is in Yangju City, the actual operational area covers the entire border region in northern Gyeonggi Province, including Paju and Yeoncheon.
3. DMZ Search Route Clearing Operations and Missions
Soldiers of the 25th Division diligently perform search and reconnaissance missions by deploying directly into the DMZ, in addition to routine fence guarding. The DMZ where the incident occurred is a dangerous area where the scars of the Korean War remain intact, with numerous mines and unexploded ordnance buried. Therefore, search route clearing operations must be conducted periodically to create safe passages for soldiers and officers. Clearing search routes is an extremely grueling task that involves using specialized equipment, such as metal detectors, to carefully identify and remove hidden hazards in the ground.
A precise search process was essential to ensure safe conditions ahead of the on-site investigation by the United Nations Command. Unlike cleaning a regular road, the operation is conducted under extreme tension where a single misstep could endanger one’s life. The soldiers deployed to the site strive to follow strict safety protocols, but it is difficult to completely locate explosives buried long ago whose positions have been lost. This incident is a regrettable event that occurred while the unit was doing its best to perform its mission despite these unavoidable risk factors.
DMZ search route clearing is a dangerous yet crucial operation that uses metal detectors to secure safe passages.
4. Circumstances of the 25th Division Mine Explosion Incident
Around 10:50 AM on September 21, 2026, an unidentified explosion occurred in the DMZ on the western front under the jurisdiction of the ROK Army 25th Division. At the time, a search route clearing operation was in progress, and the sudden explosion injured three military officers who were participating. Immediately after the incident, military authorities activated their emergency response system, rapidly evacuating the injured soldiers and securing the scene. According to media reports, the explosion is highly likely to have been caused by a mine, and the military and relevant agencies are analyzing the exact cause.
The sudden news from the frontline unit on a peaceful weekend morning shocked and saddened many citizens. Military experts analyze that identifying the cause of the accident may take some time due to the unique topographical changes in the DMZ and the characteristics of lost explosives. All possibilities are open, including whether it was recently buried by North Korean forces or whether it was an item buried by our military in the past that has shifted. The military authorities maintain their stance of refraining from hasty speculation and conducting a thorough scientific investigation to leave no room for doubt.

5. Status of Injuries and Current Measures
A total of three dedicated military officers were injured in this DMZ mine explosion, causing great sorrow. In particular, two of the injured sustained serious injuries from the blast’s impact and were immediately airlifted to the Armed Forces Capital Hospital by military emergency helicopter. It is reported that one of the injured suffered a critical injury involving the amputation of an ankle, requiring urgent treatment and rehabilitation. The other soldiers involved in the operation were also transported to the hospital immediately after the incident for physical examinations and psychological stabilization.
Many citizens are pained by the news that ROK soldiers who were sweating it out on the frontline to protect the country have been injured. The military has prioritized the treatment of the injured soldiers, mobilizing all available medical resources to support their rapid recovery both materially and mentally. Additionally, specialized psychological counseling programs are being conducted to prevent post-traumatic stress disorder (PTSD) among other soldiers who were present at the scene. Warm encouragement and support from the entire nation are essential to help the injured soldiers recover their health and return to their daily lives and units as soon as possible.
Three soldiers were injured in this incident, with two seriously injured personnel being urgently evacuated to the Armed Forces Capital Hospital for treatment.
6. Military Response to the Mine Incident and Future Outlook
The Joint Chiefs of Staff and Army authorities are conducting on-site forensics and detailed investigations to clarify the exact circumstances of the 25th Division mine explosion. They plan to announce findings only after thorough evidence collection, without making hasty judgments about the exact type of explosive or the entity responsible for burying it. Due to the unique nature of the DMZ, it is inevitably difficult to clearly distinguish whether it was an intentional provocation by North Korea or a natural displacement. The military intends to re-examine all search operation procedures for frontline units from scratch and further strengthen safety measures in light of this incident.
There is a growing voice that the safety of soldiers risking their lives to perform missions for national defense must be prioritized above all else. In the future, the military will additionally deploy the latest mine detection equipment and supplement operational guidelines for hazardous areas to prevent similar accidents. Readers, please remember the efforts of ROK soldiers working hard on the frontline and join in wishing for their rapid healing and safety. We sincerely hope that the soldiers of the 25th Division, who firmly guard the forefront of South Korea’s security, can safely complete all their missions.
Military authorities plan to comprehensively reinforce safety measures for frontline unit operations based on a thorough investigation of the cause of the accident.
