On September 14, 2003, Senior Commander of U.S. forces in Iraq, “General [Ricardo] Sanchez ‘signed a memorandum authorizing a dozen interrogation techniques beyond [U.S. Army] Field Manual 34-52–five beyond those approved for Guantanamo’–and Under-Secretary of Defense Stephen Cambone testified later before a Senate Committee that severe and ‘stress matrix’ tactics, including the use of dogs to intimidate, had been approved by U.S. commanders in Iraq, whereas others added that such measures included the use of hoods, ‘fear up harsh,’ isolation for longer than thirty days, ‘sleep management,’ and ‘sensory deprivation.’ ”
