From its establishment in 1966 to its demise in the early 1980s, the Guardian’s Office (GO) of the Church of Scientology carried out numerous covert operations and programs against a range of perceived opponents of Scientology in the United States and around the world. The GO sought to discredit, destroy or otherwise neutralize – or “depower”, in Scientology jargon – any group or individual that it regarded as anti-Scientology. Instructions for such operations were distributed in the form of individually numbered “Guardian Program Orders”, abbreviated as GPgmOs, which were distributed from the GO leadership to GO branches in Churches of Scientology and ultimately used to task agents.
