On the morning of October 25, a woman in her 30s cut through detection sensors surrounding the barbed wire fence at a general outpost (GOP) in Cheorwon, Gangwon Province. This location is just over 2 kilometers from the military demarcation line. The woman had entered the civilian control line (CCL) north of the border without permission the previous afternoon. The military spotted her via closed-circuit television (CCTV) but failed to apprehend her until she began cutting the sensors, taking about 20 hours from the initial sighting to her capture. As concerns mount over security breaches at the frontline, the military is planning to reduce the number of troops guarding this fence to one-quarter of the current level.
Repeated Security Failures: From Knock Defections to Civilians
During a National Assembly Defense Committee audit held the following day, lawmakers engaged in heated exchanges. Seong Il-jong, a member of the ruling People Power Party, questioned, "It took 20 hours to cut the wire after the initial sighting. Could we not confirm this person on CCTV before the cutting?" Defense Minister Kang Shin-cheol initially responded, "The GOP has not been breached," but faced pushback, leading him to concede, "That is indeed a breach." Joint Chiefs of Staff Chairman Jin Young-seung acknowledged that the delay in securing the individual was a problem and vowed to address it. The Joint Chiefs stated that the CCL is not a line for monitoring citizens, arguing that the term 'breach of the CCL' is inaccurate.
Shortages of Advanced Equipment and Personnel: The System's Reality
While there is contention over terminology, the scrutiny of frontline security is not new. In October 2012, a North Korean soldier defected by knocking on the door of a GOP barracks in Goseong, known as the 'knock defection.' At that time, then-Defense Minister Kim Kwan-jin acknowledged a "clear failure of security operations" and publicly apologized, resulting in disciplinary action against 14 officials, including five generals.
Similar incidents have continued since then. In 2019, a North Korean fishing boat entered the port of Samcheok without triggering the coastal surveillance system, leading to the dismissal of the 8th Army commander. In November 2020, a North Korean man crossed two layers of the GOP fence without triggering alarms, and the military apprehended him only after 14 hours. In February of the following year, a North Korean man wearing flippers entered through a coastal drainage system, and on January 1, 2022, another defection occurred in the same area. In June of this year, a North Korean soldier defected by crossing a minefield and the fence, while other North Korean soldiers nearby were not detected by surveillance equipment.
Reducing Troops Guarding the Fence: From 22,000 to 6,000
In light of these challenges, the military is planning a complete overhaul of the GOP security system. Currently, about 22,000 troops are stationed at GOP and forward observation posts (GP), but the plan is to reduce this number to 6,000 at the fence line, with the remaining 16,000 on standby in the rear to be deployed as needed. By 2040, the military aims to fill the gaps with an AI-based unmanned system. Former Defense Minister An Gyu-baek announced in April that the focus of security would shift from the fence line to a regional defense concept, with plans to trial unmanned surveillance equipment at one GP along the eastern front as early as 2029.
This shift is driven by a demographic crisis, with only about 110,000 male newborns in 2023. Projections indicate that the number of individuals eligible for military service will decrease to around 160,000 annually, making it difficult to maintain a standing army of 500,000. Kang Geon-jak, the former commander of the Army Training Command, stated at a forum last year, "No country in the world deploys a regular standing army in such large numbers for security operations," advocating for the scientific modernization of security.
Additionally, the government plans to raise the CCL by an average of 2 kilometers northward starting next year to ease restrictions in border areas. This will bring the CCL closer to the military demarcation line, raising concerns following this incident. Shin Jong-woo, secretary-general of the Korea Defense Security Forum, warned that as the CCL moves north, civilians will find it easier to approach the GOP area, necessitating measures to mitigate this risk. Yang Wook, a research fellow, cautioned that the space from the Demilitarized Zone (DMZ) to the CCL plays a crucial role in providing the military with necessary operational time, stating, "Relying on barriers established by North Korea and reducing the depth of our defense line could be a military blunder."
In a reality where troop numbers are decreasing, relying on machines for security presents significant challenges. The issue lies in the sequence of changes. Equipment generates false alarms annually, and the military failed to locate a single civilian for 20 hours. Reducing personnel guarding the fence before establishing confidence in the security system could lead to even greater gaps. The echoes of the knock from 14 years ago still resonate.
