Pride-and-ego down is a US army term that refers to humiliation techniques used by captors in interrogating prisoners to encourage cooperation, usually consisting of "attacking the source's sense of personal worth" and in an "attempt to redeem his pride, the source will usually involuntarily provide pertinent information in attempting to vindicate himself." [1] Official documents state that such techniques should not go "beyond the limits that would apply to an EPW [enemy prisoner of war].".
