Sworn statement of a Staff Sergeant, US Army Reservist- member of GTMO Tiger Team, which deployed to Abu Ghraib prison from early October 2003 until mid December 2003. Recalled interview techniques, including 'fear up' and 'ego down,' stated the techniques were verbal and not abusive. Also observed sleep deprivation being used and stress positions (make the detainee stand or sit/stand/sit repeatedly). Did not observe naked detainees, but heard a detainee in Tier 1B being stripped down and another being shackled because he would spread/eat his own feces. Did not observe dogs in AG, but knew it was a 'fear up' technique used in GTMO.
