UNIT Central Control
From Tardis Wiki, the free Doctor Who reference
UNIT Central Control co-ordinated UNIT operations from Geneva. Alistair Gordon Lethbridge-Stewart reported to them during the Cyberman invasion in the late 20th century (DW: The Invasion) and threatened to contact them other times.
In 2009, UNIT Central Control declared its highest alert in the face of a Dalek invasion. (DW: The Stolen Earth)
