UNIT Central Control was placed in Geneva. (TV: The Invasion et al) This was done after a direct appeal by Alistair Gordon Lethbridge-Stewart. (PROSE: Who Killed Kennedy) UNIT's international status would allow it to go over the head of British military figures, (TV: The Invasion) but this also meant the authorities didn't trust it. (TV: The Ambassadors of Death)

General Carrington advised the UN Security Council to coordinate a global nuclear assault on the Ambassadors' spaceship. The Council could not agree on how to respond, leaving Carrington frustrated. (TV: The Ambassadors of Death)

In 2008, the UN went into emergency session as the Moon was drawn towards Earth. (TV: The Lost Boy)

By the 2009 Sontaran invasion of Earth, UNIT themselves identified as the "Unified Intelligence Taskforce.

(TV: The Poison Sky)

(TV: The Stolen Earth)

During the Miracle Day phenomenon in 2011, which rendered humanity immortal yet still susceptible to injury or disease, China made a threat to the United Nations that they would undervalue the currency down to fifty percent. (TV: Rendition) PhiCorp established overflow camps for patients, issuing a strategy to the United Nations. (TV: Escape to LA) Soon after, the UN officially sanctioned the category system, which they called a radical new start for the health of humanity. Jack Harkness observed that this gave them the power to define both life and death. (TV: The Categories of Life) Eventually, China withdrew from the United Nations and closed their borders. (TV: The Gathering)

In the year 4000, Marc Cory, Gordon Lowery, and Jeff Garvey scout Kembel, the most dangerous planet in the universe, seeking to learn of the Daleks' presence and plans. Their ship is from the United Nations Deep Space Force Group 1.

Behind the scenes
After the broadcast of Aliens of London, it was announced that the United Nations were no longer happy to be directly associated with UNIT. The term "UN" could, however, be used as long as it wasn't stated what it stood for. Later, UNIT was shown to stand for Unified Intelligence Taskforce, with the United Nations being mentioned as providing the organisation with unlimited funding.
