This Sergeant was assigned to Abu Ghraib prison from May 22, 2003 to November 4, 2003. The Sergeant stated "MPs never used physical force, withheld food, humiliated or otherwise abused detainees as a control measure. Military Police (MP) were asked to provide security for interrogations and I observed Military Intelligence (MI) interrogations both in the hard Site (Tier IA) and in tents in Camp Vigilant. I saw MI use stress positions (standing, arms outstretched) and believe this was an effective technique. I did not consider it to be abusive or employed excessively. MI also employed sleep deprivation and verbal assault (yelling) techniques. I never saw MI do anything I'd consider really "crazy.' MI (both sokliers and Other Government Agencies (OGA)) did use clothing removal as an interrogation technique in Tier IA. It was not conunon but it was routine and authorized by Ml."
