US Army 1960s Polygraph Training

The primary mission of military intelligence in the United States Army is to provide timely, relevant, accurate, and synchronized intelligence and electronic warfare support to tactical, operational and strategic-level commanders. The Army's intelligence components produce intelligence both for Army use and for sharing across the national intelligence community. The military will subject someone to a polygraph for several reasons: If that person needs to access confidential files; if they are accused of leaking government secrets; if they are accused of terrorism or of being a spy; if they are a foreign national who needs access to classified material, and several other reasons. The following is a 1960s Army training recording with information on administering a lie detector test.
