The Montauk Project was purportedly established to continue the kinds of secret research that had begun with the Philadelphia Experiment. One of their alleged experiments was said to be a mind control program on boys between the ages of 6 and 22 who were brought to a secretive base at Montauk, Long Island in the 1970's.
In the book, Montauk Revisited, Preston Nichols writes that the idea with some of the younger boys was to assimilate them into society after they had been programmed, and then they'd be answerable to the "secret government" on both a "psychotronic/hypnotic basis or verbal command." The long-range plan was to activate them during periods of unrest, "so that they band together into vigilante squads and go after government enemies."
