The Marine Corps Command and the Northwest Islands Defense Command said on 22 October that they are holding the second-half 2026 joint island defence drill on Baengnyeong, Yeonpyeong and other Northwest Islands. The drill, part of the 2026 Hoguk training, runs from 19 to 23 October. [ 1 , 2 , 3 , 4 ]
Yonhap and Asia Economy describe the exercise as annual. They say it is led by the Northwest Islands Defense Command, under the Marine Corps commander, with joint forces from supporting operations commands, to verify integrated response capability and keep up the defence posture on the islands. Newsis says it was designed to test how local and reinforcement forces respond together to an enemy provocation. [ 1 , 2 , 4 ]
Besides the two commands, the Army Ground Operations Command, Navy Operations Command, Air Force Operations Command and Aviation Command are taking part. About 6,000 troops, ships, aircraft and drones are involved. [ 1 , 2 , 3 , 4 ]
The scenario assumes a combined provocation including enemy firepower, high-speed aircraft, cruise missiles and suicide drones. The drill began as reinforcements, including the Marine Corps rapid reaction force, deployed to the islands by sea and air. Newsis published a photo of the force's K808 wheeled armoured vehicle moving to Baengnyeong on 20 October by civilian vessel. [ 1 , 2 , 3 , 4 ]
Reinforcements practised joint fire response, integrated air defence, anti-landing defence and counter-terrorism, and supported a residents' evacuation drill. Newsis says units also rehearsed mission procedures and checked coordination between commands. [ 1 , 2 , 3 , 4 ]
The drill also reflects changes in modern warfare and combat lessons analysis. It covers counter-drone protective structures, resupply of repair parts by transport drones and unmanned surface vessels, and electronic warfare training. Newsis adds mass casualty treatment and firing drills. Field training and command post exercises run in parallel. [ 1 , 2 , 3 , 4 ]
Lt. Col. Do Il-seon (도일선), the Yeonpyeong unit's battalion commander, said the unit would complete its mission to defend the Northwest Islands under any circumstances. Newsis says the two commands plan a post-drill review to identify improvements. [ 1 , 2 ]
Why it matters
The outlets present the drill as a way to test how local forces and reinforcements work together on the Northwest Islands. Yonhap and Asia Economy describe it as an annual exercise held as part of the 2026 Hoguk training.
