The United Nations Intelligence Taskforce, commonly referred to as UNIT was a military organisation which operated under the auspices of the United Nations.
History
Roots
The roots of UNIT itself, however, lay in later alien encounters. The Intrusion Counter-Measures Group headed by Group Captain Ian Gilmore, which got involved in the Shoreditch Incident, served as a specialised military force with scientific assistance would seem almost a trial run for UNIT, though not an international organisation. Though Gilmore did have two scientific advisors serving much as the third incarnation of the Doctor and Dr Elizabeth "Liz" Shaw would later, the seventh incarnation of the Doctor did most of the work on the technical end. (DW: Remembrance of the Daleks, Who Killed Kennedy?)
An incident which led directly to the creation of UNIT was the takeover of London by the Great Intelligence, with robot Yetis and a deadly cobweb-like fungus. Assisted by the Second Doctor, another group of British infantrymen, led by then-Colonel Alistair Gordon Lethbridge-Stewart, beat back the Yeti from the tunnels of the London Underground. (DW: The Web of Fear) In reaction to the London Event, the British government formed the Home-Army Fifth Operational Corpsto combat alien threats, headed by Lethbridge-Stewart. Lethbridge-Stewart was part of the organisation until the formation of UNIT in 1969 (DW: Who Killed Kennedy?)

Early history
Formation
The United Nations were aware the world faced threats from extraterrestrial sources. As space programmes sent probes deeper and deeper into space, mankind was drawing attention to itself. (DW: Spearhead from Space) Unable to get the British government to form a permanent special operations force for alien threats, Lethbridge-Stewart went over their heads to the UN Security Council, who proved more receptive. (DW: Who Killed Kennedy?) The UN established UNIT with the mandate to investigate, monitor and combat such threats. At the suggestion of Gilmore from the ICMG, (DW: The Scales of Injustice) Lethbridge-Stewart was put in charge of the British contingent. (DW: The Invasion) This contingent was organisationally known as Department C19 within the British government. (DW: The Scales of Injustice)
Alistair Gordon Lethbridge-Stewart
One of UNIT's first missions was an intensive investigation of International Electromatics, which turned violent. UNIT agents were killed and UNIT launched a helicopter raid to liberate prisoners at an Electromatics' facility. With the help, again, of the Second Doctor, UNIT discovered the company was a front for a Cybermen invasion, and was able to defend against it. (DW: The Invasion)
Lethbridge-Stewart became convinced of the necessity of scientific advice in battling extraterrestrial threats. He recruited Liz Shaw from the University of Cambridge. Around that same time, the Third Doctor had been exiled to Earth by the Time Lords. He agreed to join UNIT as its scientific advisor just in time to help defeat the Nestene Consciousness' invasion of Earth using its Autons in an attack on the Auto Plastics factory. (DW: Spearhead from Space)
The Doctor continued to assist UNIT. In Wenley Moor, UNIT soldiers guarded the cave entrances to prevent the Silurians from getting out. Against the Doctor's wishes, the Brigadier ordered Corporal Nutting to blow up the Silurian base beneath Wenley Moor, permanently sealing the base off. (DW: Doctor Who and the Silurians) While the third incarnation of the Doctor stated in some accounts that this tribe had all died, (DW: Doctor Who and the Silurians) According to another account, the Ninth Doctor said they were only entombed. (DW: The Scales of Injustice) UNIT also encountered the Primords. (DW: Inferno)
