Strategic Scope of US Marine Drills South Korea 2026

The U.S. military announced that the battalion, part of a temporary deployment, conducted exercises from Nov. 29, 2025, to last Saturday, Jan. 10, 2026. The maneuvers spanned from Camp Humphreys in Pyeongtaek, located 60 km south of Seoul, to firing ranges just 32 km south of the Demilitarized Zone (DMZ).
