"The Devil Goblins from Neptune" (1997) by Keith Topping and Martin Day introduced a division within the Central Intelligence Agency headed by a man known only as Control, which has featured as a rival to UNIT in subsequent novels "The King of Terror" and "Escape Velocity", "King" seeing the Fifth Doctor working with the Brigadier on an investigation in 1999 that forces them to work with the CIA and Control, and "Escape" depicting Control trying to deal with a new alien presence on Earth before UNIT discover it, only for the threat to be thwarted by the amnesic Eighth Doctor. "Alien Bodies" (1997) by Lawrence Miles introduced a more ruthless UN division called UNISYC (United Nations Intelligence Security Yard Corps), which by the 2040s has replaced UNIT.
