The Korean military has shifted its focus from assigning blame to preventing a recurrence after an internal investigation into last week's misidentification of a U.S. Marine Corps drone found procedural shortcomings on both sides.
The Joint Chiefs of Staff (JCS) concluded that failures by both Korea and the U.S. contributed to the incident, in which a U.S. drone flying during a bilateral exercise was mistaken for an unidentified aircraft, triggering the military's highest-level counter-drone response.
These findings have prompted follow-up measures aimed at strengthening airspace coordination while broader command responsibilities also came under review.
According to the JCS, a working-level officer at the Army’s 1st Corps received a text message from the U.S. side a day before the flight but failed to relay the information to higher headquarters or relevant units. The text referenced only a previously approved live-fire altitude, but an official document attached as a photo to the message specified the drone's actual planned flight altitude — the detail that should have triggered a report up the chain of command.
