In 2008, UNIT Central witnessed the assassination of American President Arthur Coleman Winters aboard the aircraft carrier Valiant by a Toclafane acting on the orders of British Prime Minister Harold Saxon, actually. After the Year That Never Was was reversed, a transmission from UNIT Central, asking for clarification, was heard but not answered aboard the flight deck within the Valiant.

Behind the scenes
In The Van Statten Code, a puzzle-game in Doctor Who Annual 2006 not considered a valid source due to casting the reader as a character in the Doctor Who universe, "UNIT Headquarters in Geneva" receive a short message in Van Statten Code warning them to "beware the Bad Wolf".
