The Armed Forces of the Philippines has been a participant in various regional conflicts, including the Korean War and the Vietnam War. Recently, the Philippines sent peacekeeping forces to Iraq, in addition to civilian doctors, nurses and police. However, the Filipino mission was later recalled as collateral for the release of a Filipino hostage. As part of a UN Peacekeeping Operation, Philippine Army General Jaime de los Santos became the first commander of troops responsible for maintaining order in East Timor.
