MAJESTIC

The highest security level known, higher than the Atom Bomb and effectively thirty-eight levels higher than Top Secret due to the compartmentalization of information. There are allegedly over thirty compartments of Top Secret which means that if you have a Top Secret clearance, it doesn't mean that you have access to all Top Secret documents, you must require the "need to know". Documents that require the"need to know" are classified as Top Secret xxx, where xxx can be any one of over thirty code names. Documents about S-4 / AREA 51 happenings are classed as "Majestic".
