CIA operatives like Jerry Daniels worked hand in glove with General Vang Pao and the Hmong to conduct the Secret War in Laos. Hmong men and boys were recruited as soldiers for Special Guerrilla Units (SGU)—unofficial surrogates of the US armed forces. Many SGUs lost their lives defending US interests in Laos. The US radar facility Lima Site 85, also known as Phou Pha Thi, was one such loss.
