List of UNIT personnel

UNIT stands for UNified Intelligence Taskforce, (formerly it stood for United Nations Intelligence Taskforce), a fictional entity in the Doctor Who universe.

UNIT first appeared in the Second Doctor serial The Invasion, (1968), although Alistair Gordon Lethbridge-Stewart had appeared earlier in The Web of Fear (1968) as a colonel.

UNIT went on to feature in many Third Doctor stories, as the Doctor is shown being exiled to Earth in Spearhead from Space (1970), and becomes UNIT's Scientific Advisor following the Auton attack. The Doctor would maintain this post in subsequent incarnations. UNIT is a large organisation and many personnel have featured in Doctor Who over the years. Some lead, supporting and recurring characters have worked for or have been affiliated with the organisation.

The Doctor

UNIT's principal scientific advisor since his third incarnation was exiled to Earth (having periodically collaborated with UNIT during his second incarnation)^[19][27] the Doctor has maintained a loose affiliation with UNIT in all his subsequent bodies. The Doctor departed from UNIT's full-time employ during his fourth incarnation,^[28] leaving a space-time telegraph^[29] (and, later, the TARDIS' telephone number)^[30] with which he could be summoned in emergencies. He retains his credentials, still bearing his third incarnation's portrait;^[5] and, initially, UNIT personnel Surgeon-Lieutenant Harry Sullivan and Sarah Jane Smith as his companions. Despite the looseness of his UNIT affiliation and his frequent disagreements with the organisation, the Doctor continues to consider UNIT's scientific advisor to be his job, even into his eleventh incarnation; when advising UNIT leader Kate Stewart in "The Day of the Doctor" (2013), the Eleventh Doctor insists to a sceptical Clara Oswald, "I work for them. … This is my job."^[4]

Despite enjoying UNIT's confidence and admiration, the Doctor's extraordinary abilities and independence concern UNIT to the point that the Black Archive is designed to be impenetrable by his TARDIS, although it remains vulnerable to his subterfuge.^[4]

She is killed alongside her colleagues, fellow experts, by the Slitheen, electrocuted by devices planted on their nametags.^[32] Her name, 'Frost', is only given on her name tag and it has led to fan speculation that it is derived from character Muriel Frost, featured in the comic strip in Doctor Who Magazine. This argument is fuelled by earlier drafts of the episode's script that had the Doctor refer to her directly as "Muriel Frost". However, in this episode, she is dressed in US military uniform. According to the UNIT website set up by the BBC, she was commander of the Geneva EVA Team.

She has A+ blood, which meant she succumbs to the Sycorax mind control. As a result of this, she stands poised to jump off the roof of the Tower of London. When the Doctor presses a glowing red button aboard the Sycorax ship, the humans affected are released from the Sycorax mind-control and come down from the roof safely, but confused, with no memory of how they got up there.^[18]

Appears in	"The Sontaran Stratagem" / "The Poison Sky"

Colonel Mace is the commanding officer of a large contingent of UNIT, appearing in "The Sontaran Stratagem" / "The Poison Sky" (2008). He originally seems to view the Doctor as a superior officer, saluting him and taking his orders; however, the two clash and Mace begins to be irritated by the Doctor's manner and repeated casual dismissals of him and UNIT, while simultaneously irritating the Doctor through his overtly militaristic manner and insistence on a combat solution to the situation brought on by the Sontarans (Although both agree that the presence of 'Sir Alistair' would be of great assistance at this time).

Despite repeatedly being told UNIT could not face the Sontarans, he organises the troops for an assault on a Sontaran position, telling the Doctor he is not listening any more, and rallies the troops with a speech about how they would show "every passing alien with an axe to grind" to not mock them and see "what the human race is capable of". He even manages to impress the Doctor by having the Valiant clear away the poison gas surrounding the factory. He then successfully leads the recapture of the area, managing to personally kill the Sontaran second-in-command, Commander Skorr.^[30][34]

Although Colonel Mace's first name was never mentioned on screen, the letter initial of A can be seen on the I.D. Card displayed on his uniform. On Page 129 of the reference book The Time Traveller's Almanac, it says that the A stands for Alan.

Magambo returns in the 2009 episode "Planet of the Dead", this time on a non-parallel Earth, as a senior officer of a UNIT patrol. She leads a team of UNIT soldiers and Doctor Malcolm Taylor who were investigating a wormhole which was, unbeknownst to them, created by the deadly Swarm. Taylor and Magambo aid the Doctor's attempt to return to planet Earth from San Helios from the Earth side of the wormhole; however, when the Doctor refuses to give full details of the impending Swarm, she considers shutting the wormhole down to save the planet. Malcolm refuses to shut the wormhole without the Doctor coming back through and resists even under the threat of Magambo shooting him. Yet the Doctor was able to come back through with the aid of the modified 200 Bus and Magambo leads her troops in destroying the three Swarm aliens that come through the wormhole before its closure. After thanking the Doctor and bringing his TARDIS back to him (apparently it had been found in the gardens of Buckingham Palace), she comments on having to clear up the mess, to which the Doctor refused to help in the paperwork.^[46]

She is shown to be eager to please the Doctor and admires him. The Twelfth Doctor hints that he might consider making her a companion, but she is disintegrated by Missy in "Death in Heaven". Osgood displayed a great deal of self-control as she near-calmly tried persuading Missy to spare her with logical explanations.^[3]

Despite her apparent death, Osgood returned alongside the Zygons again in the two-parter "The Zygon Invasion" / "The Zygon Inversion". It is revealed in "The Zygon Invasion" that either a Zygon duplicate created during the events of "The Day of the Doctor" or her real self was killed by Missy in "Death in Heaven", but the other one survived, causing a breakdown in the treaty between the humans and the Zygons. Once the crisis is resolved in "The Zygon Inversion", her identity as human or Zygon is left ambiguous, and Osgood gains a new "sister" in another Zygon named Bonnie who assumes her form to renew the treaty.
