"Finally came Category III. These methods were to be used for only a very small percentage of detainees - the most uncooperative (said to be fewer than 3%) and exceptionally resistant individuals - and required approval by the commanding general at Guantánamo. In this category were four techniques: the use of "mild, non-injurious physical contact", such as grabbing, poking and light pushing; the use of scenarios designed to convince the detainee that death or severely painful consequences were imminent for him or his family; exposure to cold weather or water; and, finally, the use of a wet towel and dripping water to induce the misperception of suffocation. This last technique came to be known as water-boarding, described on a chat show by the vice-president, Dick Cheney, as a "dunk in the water" and a "no-brainer" if it could save lives." (thanks May)
