The SERE program, which Mitchell and Jessen would reverse engineer, was used to train pilots and other soldiers on how to resist "brainwashing" techniques assumed to have been employed by the Chinese to extract false confessions from captured Americans during the Korean War. The program subjected trainees to "waterboarding ... sleep deprivation, isolation, exposure to extreme temperatures, enclosure in tiny spaces, bombardment with agonizing sounds at extremely damaging decibel levels, and religious and sexual humiliation," including forced enemas and other anal assault. Under CIA supervision, Miller and Jessen adapted SERE into an offensive program designed to train CIA agents on how to use the harsh interrogation techniques to gather information from terrorist detainees. In fact, all of the tactics listed above would later be reported in the International Committee of the Red Cross Report on Fourteen High Value Detainees in CIA Custody as having been used on Abu Zubaydah.
