High Quality Content by WIKIPEDIA articles! Laos Site 85 (LS-85 alphanumeric code, "Lima Site 85" with phonetic 1st letter for cover) was a clandestine Laos military installation of the Hmong "Secret Army", the Central Intelligence Agency, and the United States Air Force used for Vietnam War covert operations against targets in the neutral Laos. Initially created for a CIA command post to support a local stronghold, the site was expanded with a 1966 TACAN area excavated on the mountaintop where a 1967 command guidance radar was added for Commando Club bombing of northern areas of North Vietnam. The site ended operations with the Battle of Lima Site 85 when most of the U.S. technicians on the mountaintop were killed, including SMSgt Richard Etchberger who was awarded the Medal of Honor.
