Army Field Manual 2 22.3, or FM 2-22.3, Human Intelligence Collector Operations, was issued by the Department of the Army on September 6, 2006. The manual gives instructions on a range of issues, such as the structure, planning and management of human intelligence operations, the debriefing of soldiers, and the analysis of known relationships and map data. The largest and most newsworthy section of the document details procedures for the screening and interrogation of prisoners of war and unlawful combatants. Political issues Drafting of the manual reflected concerns about enhanced interrogation techniques and/or torture, such as water boarding, that followed after a 2003 memo by John Yoo determined that the wartime authority of the U.S. president overrode international agreements against torture. Revision of the manual from the previous FM 34-52 Intelligence Interrogation followed passage of a law in 2005, pressed by Senator John McCain, that caused interrogation techniques not included in the manual to be considered illegal for the U.S. Army, but not for the CIA. Therefore, the release of the manual was seen to prohibit Army personnel from methods such as mock executions, sexual humiliation, hooding prisoners and "waterboarding". On March 8, 2008 president George W. Bush vetoed a bill, supported by Democrats and opposed by John McCain, which would have restricted the CIA to the techniques in the manual. Disputes during the manual's preparation included whether a section on interrogation techniques would remain classified, and whether the Geneva conventions ban on "humiliating and degrading treatment" would be removed. Executive Order 13491, issued by Barack Obama on January 22, 2009 (two days after Obama's inauguration) revoked Executive Order 13440 of July 20, 2007. It restricted the CIA and other Executive Agencies to proceed with interrogations "strictly in accord with the principles, processes, conditions, and limitations [Army Field Manual 2 22.3] prescribes". Persons associated with the U.S. government were advised that they could rely on the manual, but could not rely upon "any interpretation of the law governing interrogation – including interpretations of Federal criminal laws, the Convention Against Torture, Common Article 3, Army Field Manual 2 22.3, and its predecessor document, Army Field Manual 34 52 issued by the Department of Justice between September 11, 2001, and January 20, 2009." This order restricted the CIA and all other U.S. personnel to the same rules that the military uses in interrogations. Newsweek described the impact of this and three other
