2002, this training program was adopted as a source of interrogation techniques to be used in the newly declared "War on Terror". When it was adopted for use at the Guantánamo detention and interrogation facility the only change that was made to Biderman's Chart of Coercion was to change the title (originally called "Communist Coercive Methods for Eliciting Individual Compliance"). The training document instructing on the use of these "coercive" methods was made public at a United States Senate Armed Services Committee hearing (17 June 2008) investigating how such tactics came to be employed. Col. Steven Kleinman, who was head of a team of SERE trainers, testified before the Senate committee that his team had been put under pressure to demonstrate the techniques on Iraqi prisoners and that they had been sent home after Kleinman had observed that the techniques were intended to be used as a "form of punishment for those who wouldn't cooperate", and put a stop to it. Sen. Carl Levin (chairman of the Senate Armed Services Committee) was quoted after reviewing the evidence as saying: What makes this document doubly stunning is that these were techniques to get false confessions. People say we need intelligence, and we do. But we don't need false intelligence. Camp detainees Since January 2002, 779 men have been brought to Guantanamo. Nearly 200 were released by mid-2004, before there had been any CSRTs (Combatant Status Review Tribunal) to review whether individuals were rightfully held as enemy combatants. Of all detainees at Guantanamo, Afghans were the largest group (29 percent), followed by Saudi Arabians (17 percent), Yemenis (15 percent), Pakistanis (9 percent), and Algerians (3 percent). Overall, 50 nationalities were present at Guantanamo. Although the Bush administration said most of the men had been captured fighting in Afghanistan, a 2006 report prepared by the Center for Policy and Research at Seton Hall University Law School reviewed DoD data for the remaining 517 men in 2005 and "established that over 80% of the prisoners were captured not by Americans on the battlefield but by Pakistanis and Afghans, often in exchange for bounty payments." The U.S. widely distributed leaflets in the region and offered $5,000 per prisoner. One example is Adel Noori, a Chinese Uyghur and dissident who had been sold to the US by Pakistani bounty hunters. Top DoD officials often referred to these prisoners as the "worst of the worst", but a
