which usually were composed of three soldiers, one from the U.S., one from the U.K., and one from France. The earliest US soldiers involved in UW were in the Philippines, soon allied with Filipino forces, and who declined to follow Japanese orders to surrender, such as Wendell Fertig. While not trained in UW, Fertig, along with other U.S. and Filipino leaders, eventually created guerrilla forces fighting the Japanese, forces that numbered in the tens of thousands. A few experienced soldiers' ability to train and lead a quite large resistance was a guiding principle of the formation of United States Army Special Forces in 1952. 1950s model of resistance to invasion of Europe After World War II, the original SF mission of UW, as shown in the first SF deployment of the 10th Special Forces Group to Europe, was in expectation of a Soviet attack on Western Europe. SF would help organize, train, and lead resistance movements to such an invasion. A 1951 doctrine for UW, still called guerrilla warfare at that point, was: 1960s model of dealing with wars of national liberation When American advisors were sent to Laos and South Vietnam in the fifties and early sixties, the major problem was not to create guerrilla units, but to fight existing Laotian and Vietnamese guerrilla forces. To them it seemed logical that soldiers trained to be guerrillas would have a deep understanding of how to fight guerrillas, so Special Forces was given that mission. The White Star mission in Laos was initially covert, and used Special Forces and other personnel under Central Intelligence Agency control. Whether the mission is called counterguerrilla, counterinsurgency, or foreign internal defense, it involves assisting a friendly government—the "foreign" in FID—to defend against guerrillas acting inside its borders. FID can also involve training a foreign government to deal with a future internal guerrilla threat. Later in Southeast Asia, SF personnel, often assigned to the Studies and Observation Group, carried out SR missions against infiltrators from the North, directing air strikes and assessing damage. 1970s and 1980s In the 1970s, until the NCA withdrew them as part of its "tilt" to Iraq, SF supported Kurdish resistance to Iraq under Saddam Hussein. In the 1980s, SF worked with the Afghan Mujahideen against the Soviets, but in a role of supporting rather than leading the local personnel. They did not need to create an underground and an auxiliary, and
