“…on April 16, 2003, Secretary [of Defense Donald] Rumsfeld approved twenty-four interrogation tactics from among thirty-five recommended by the DOD [Department of Defense] Working Group for use on detainees at Guantanamo. Secretary Rumsfeld stated that if the U.S. Commander, [of] U.S. Southern Command required ‘additional interrogation techniques for a particular detainee,’ he should send a written request to be approved by the Secretary. Some of the tactics had been authorized in the 1992 Field Manual, but others had not been.”
