The Torture Manuals was a nickname for seven training manuals that had excerpts declassified to the public on September 20, 1996, by the Pentagon.

Other manuals were prepared by the U.S. military and used between 1987 and 1991 for intelligence training courses at the U.S. Army School of the Americas (SOA). The manuals were also distributed by Special Forces Mobile Training teams to military personnel and intelligence schools in Colombia, Ecuador, El Salvador, Guatemala, and Peru.
The manuals advise that torture techniques can backfire and that the threat of pain is often more effective than pain itself. The manuals describe coercive techniques to be used "to induce psychological regression in the subject by bringing a superior outside force to bear on his will to resist." These techniques include prolonged constraint, prolonged exertion, extremes of heat, cold, or moisture, deprivation of food or sleep, disrupting routines, solitary confinement, threats of pain, deprivation of sensory stimuli, hypnosis, and use of drugs or placebos.[29]
