Dispatches - The Guantanamo Guidebook

A manual called "Camp Delta Standard Operating Procedure" (SOP), dated February 28, 2003 and designated "Unclassified//For Official Use Only", was published on Wikileaks. This is the main document for the operation of Guantánamo Bay, including the securing and treatment of detainees. The 238-page document includes procedures for identity cards and Muslim burial. It is signed by Major General Geoffrey D. Miller. The document is the subject of an ongoing legal action by the American Civil Liberties Union (ACLU), which has been trying to obtain it from the Department of Defense.

On July 2, 2008, the International Herald Tribune revealed in an article that the U.S. military trainers who came to Guantánamo Bay in December 2002 had based an entire interrogation class on a chart copied directly from a 1957 Air Force study of Chinese Communist torture techniques used during the Korean War to obtain confessions, many of them false. The chart showed the effects of "coercive management techniques" for possible use on prisoners, including "sleep deprivation," "prolonged constraint,"also know as "stress positions" and "exposure", all of which are imposed on U.S. as well almost all military personnel as part of standard initial training (but in isolation, except for the minority who go to advanced courses). The 1957 article from which the chart was copied, written by Alfred D. Biderman, a sociologist then working for the Air Force, was entitled "Communist Attempts to Elicit False Confessions From Air Force Prisoners of War". Other techniques used by the Chinese Communists that were listed on the chart include "Semi-Starvation," "Exploitation of Wounds," and "Filthy, Infested Surroundings," along with their effects: "Makes Victim Dependent on Interrogator," "Weakens Mental and Physical Ability to Resist," and "Reduces Prisoner to 'Animal Level' Concerns." The only change made to the chart used at Guantánamo was an altered title.
