UNIT HQ

UNIT HQ was the name given to the operating base of a UNIT branch and usually refers to the headquarters of the British arm]. It is not to be confused with UNIT Central Control in Geneva (DW: The Invasion) the command and control facility for the entire international organisation.

List of known UNIT HQ Locations
UNIT HQ has occupied a number of physical locations, presumably to help keep its location a secret or adapt to current needs.

Military Plane
During the Cybermen invasion circa 1979 UNIT HQ was on a military cargo-type propeller driven aircraft. The facility included offices, a command and control centre, a vehicle bay and space and equipment for a UNIT Assault Platoon. The plane served as HQ for the officer commanding unit. There was also a Wing Commander aboard who held responsibility for flight operations. (DW: The Invasion)

Building in London
During the Auton incident UNIT HQ was in a building in London. This HQ included offices, a Science Lab and a parking garage. The guards did not wear UNIT uniforms, presumably to keep a low profile. (DW: Spearhead from Space)

Building on the edge of London
UNIT HQ later moved to a building on the edge of London. This set up featured more visible guards, offices, a parking garage and a science lab. It was briefly transported to an alternate universe by the Time Lord Omega. (DW: The Three Doctors)

Tower of London
During the Sycorax's attack of Earth, UNIT had a HQ located under the Tower of London. (DW: The Christmas Invasion)

Articulated Truck
During the Sontaran incident in 2008, UNIT maintained a mobile base in an articulated lorry. The vehicle included offices and modern command and control facilities. Nevertheless, at this time, the official HQ was still in The Tower of London. (DW: The Sontaran Stratagem)
