wall standing was common after the lash was banned by the british army. Prisoners were stood facing a wall and forced to do the manual of arms. The sleep deprivation, nakedness was pioneered by the russians in the lubyanka. The hooding is a british tool because of the overcrowding they didnt have room to move prisoners so they could see no other peisoner. Yhe noise and disasociation in classical russian. The religious aspect was of course the british again all cheerfully used and refined by the Israelis and shared with the US.
