Rex 84, short for Readiness Exercise 1984, was a classified scenario and drill developed by the United States federal government to detain large numbers of American citizens deemed to be "national security threats", in the event that the President declared a "State of National Emergency". The plan was first revealed in detail in a major daily newspaper by reporter Alfonso Chardy in the July 5 1987 edition of the Miami Herald. Possible reasons for such a roundup were reported to be widespread opposition to a U.S. military invasion abroad, such as if the United States were to directly invade Central America. To combat what the government perceived as "subversive activities", the plan also authorized the military to direct ordered movements of civilian populations at state and regional levels, according to Professor Diana Reynolds.
Earlier reports on Rex 84 were published as early as 1984 by the Spotlight newspaper ("Reagan Orders Concentration Camps") and other far right publications; as well as an affidavit filed by Attorney Daniel Sheehan of the Christic Institute in the La Penca bombing case. These claims did not prove to be reliable based on later reporting and research.
Rex is Latin for "king", see Rex (king). Specifically, it was the title of the kings of ancient Rome.
