A black operation (or black ops) is a covert operation by a government, a government agency, or a military organization. This can include activities by private companies or groups. Key features of a black operation are that it is secret and it is not attributable to the organization carrying it out.[1] The main difference between a black operation and one that is merely secret is that a black operation involves a significant degree of deception, to conceal who is behind it or to make it appear that some other entity is responsible ("false flag" operations).[2][3] A single such activity may be called a "black bag operation";[1] that term is primarily used for covert or clandestine surreptitious entries into structures to obtain information for human intelligence operations.[4] Such operations are known to have been carried out by the FBI,[5] the Central Intelligence Agency,[6] Mossad, MI6, COMANF, DGFI, RAW, MSS, KGB and the intelligence services of other nations.
