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 (e.g. false flag operations).[5][6]
^Popular Electronics, Volume 6, Issue 2–6. Ziff-Davis Publishing Co., Inc. 1974, p. 267. "There are three classifications into which the intelligence community officially divides clandestine broadcast stations. A black operation is one in which there is a major element of deception."
^Djang, Chu, From Loss to Renewal: A Tale of Life Experience at Ninety, Authors Choice Press, Lincoln, Nebraska, p. 54. "(A black operation was) an operation in which the sources of propaganda were disguised or misrepresented in one way or another so as not to be attributed to the people who really engineered it."
