South korea's marine corps has taken part in a multinational joint exercise in the philippines: the United States, the Philippines, and Japan.
According to Yonhap News Agency, South Korean troops established a joint command-and-control center with other participating countries to train staff officers in a simulated scenario as part of the command post exercise (CPX). This year, South Korean marines also shared tips on the operation and maintenance of the Korean Amphibious Assault Vehicle (KAAV) with their Filipino counterparts. The Philippine Marine Corps fielded eight such armored vehicles in 2016.
Established in 2017, the multinational drill, jointly led by the Philippine and U.S. Marine Corps, is designed to strengthen counterterrorism capabilities and coastal defense operations. South Korea has participated in the drills annually since 2022.
