Operation Raindance was a military operation of the Laotian Civil War, staged from 17 March to 7 April 1969. It was launched by the U.S. Air Force (USAF) in support of Hmong guerrillas raised by the Central Intelligence Agency (CIA). As the guerrillas were being pressured by enemy troops pushing to within ten kilometers of their main bases, the aerial campaign was planned to cause a pullback by the pressing communists.
