Oh man. @theimage13 , a GREAT place to start with the disinformation stuff is a documentary called Mirage Men. It WAS on Netflix. It will blow your mind.
Here, too, is an interesting story about alleged disinformation agent Richard Doty. I might have misremembered when saying the information was declassified: I think it's more like corroborated.
But it's fairly convincing and makes perfect sense. Another interesting thing to research is the history of projects Grudge, Sign and Blue book and the attitudes of those running the programs as well as the (sometimes internal) criticisms leveled at said programs.
As for the holographic projection pysop plans, here's an old story about It from the Washington Post.
