National Intelligence Department

A civilian branch of the United States government, which appears to have a significant military component. The agency is devoted to the protection of Earth, and thus works with -- and often comes into conflict with -- Stargate Command. The N.I.D. is plagued by a rogue group within its ranks, which operates outside the law to acquired advanced alien technologies by any means necessary. This has included use of Earth's second Stargate for covert, off-world operations, placing a mole within the S.G.C., blackmailing General George Hammond, and stealing alien technology from Area 51.

Thanks to the efforts of agents like Malcolm Barrett, the N.I.D. is now something of a more legitimate, reformed agency committed to civilian oversight of military programs. Another of its most prominent agents is Richard Woolsey.
