The Philippines was the fifth largest troop contributor and the 11
th nation to offer forces to support South Korea during the war. 

The Philippine Expeditionary Force to Korea was a reinforced combined arms battalion combat team. The first unit, the 10th Battalion Combat Team arrived in Korea on September 19, 1950. These highly mobile combat teams brought their own artillery, reconnaissance units, and engineers, medical and dental detachments, making them flexible and effective.

The 2nd, 10th, 14th 19th, and 20th Infantry Battalions rotated services during the war. They operated alongside the U.S. 1st Cavalry Division, 3rd Infantry Division, 25th Infantry Division, and 45th Infantry Division.

The units received a number of awards including the ROK Presidential Unit Citation, Philippine Presidential Unit Citation, ROK Presidential Distinguished Unit Citation, U.S. X Corps Battle Citation, and a number of individual awards including Gold Cross Medals, U.S. Silver Star, U.S. Bronze Star, Distinguished Conduct Star, and Military Merit medals.

The Philippines contributed 7,420 service members to the war effort. The ground forces departed Korea in May 1955.
The Philippines forces suffered 448 casualties including 92 members killed in action and 356 wounded in action during the war.
The Philippines has maintained a constant presence as part of UNC following the signing of the Armistice Agreement in 1953. From 1978 to 2002, the Philippines provide a Field Grade Officer as the Force Representative to UNC-Rear in Japan. Their current participation includes three non-commissioned officers in the Honor Guard (one Navy and two Air Force members). Additionally, Philippine Defense Attachés to the ROK have served as rotating members of UNC Military Armistice Commission-Secretariat. Along with their assistants, they routinely participate in Armistice maintenance tasks such as inspections in the Demilitarized Zone and investigations of alleged Armistice violations.
