This is one of the first declassified manuals released by the CIA entitled the 'KUBARK
Counterintelligence Interrogation''. KUBARK was a U.S. Central Intelligence Agency cryptonym
for the CIA itself. The cryptonym KUBARK appears in the title of a 1963 CIA document KUBARK
Counterintelligence Interrogation which describes interrogation techniques including among
other things coercive counterintelligence interrogation of resistant sources. This is the
oldest manual and describes the use of abusive techniques as exemplified by two references to
the use of electric shock in addition to use of threats and fear sensory deprivation and
isolation.
