List of UNIT personnel

From Wikipedia, the free encyclopedia
Jump to: navigation, search

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. Lethbridge-Stewart devised the organisation after the events of the Web of Fear and the RAF's ground skirmish with Daleks three years earlier[1] had demonstrated the need for a dedicated force to address alien defence.

UNIT went on to feature in many Third Doctor stories, as the Doctor was exiled to Earth in Spearhead from Space (1970), and became 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.


Corporal Adams[edit]

Corporal Adams, played by Max Faulkner, was stationed in Devesham during the Kraal invasion, as seen in the Fourth Doctor serial The Android Invasion (1975). The Kraals made an android replica of him. Faulkner had previously played a UNIT Soldier in the Third Doctor serial The Ambassadors of Death (1970).

Colonel Ahmed[edit]

Colonel Ahmed (played by Sanjeev Baskhar) was a senior UNIT officer who served during the crisis when the Earth's dead were being reconstituted as Cybermen (Death in Heaven). He served aboard the presidential aircraft Boat One, and was killed when the Cybermen destroyed the aircraft.


Atkins, played by Tom Keller, is a UNIT commissionaire who guards the entrance to the Black Archives in the dungeons below the Tower of London. The Archives' required memory wipes cause him to forget each work shift at its end. After a decade on the job, he still begins each day thinking it's his first. Seen in "The Day of the Doctor".

Appears in Battlefield
Portrayed by Angela Bruce

Brigadier Winifred Bambera, played by Angela Bruce, appeared in the Seventh Doctor serial Battlefield (1989) as UNIT's commanding officer. She worked alongside the Seventh Doctor, Ace (whom the Doctor had initially passed off as UNIT's former Scientific Advisor, Liz Shaw, with Liz's old security pass), and Brigadier Lethbridge-Stewart (pulled out of retirement for the duration of the crisis), in defeating the extra-dimensional forces of Morgaine and Mordred in Carbury. She was in command during the mid-1990s and was tasked with transporting a nuclear missile across Britain. Bambera is shown able to fight with weapons and in hand-to-hand combat. She took a no-nonsense, by-the-book approach to command that warranted the respect of those under her. Major Husak and Sergeant Zbrigniev reported directly to her. She uses the word "shame" as an expletive.

Bambera appears several times in the Virgin New Adventures novels, notably in Head Games and The Dying Days. It is revealed that she marries Ancelyn, the Arthurian knight from Battlefield, and that the couple have twins. She is mentioned as having served as a Colonel under Brigadier Crichton in the novelisation of Downtime. Her later life is seen in the Prelude to Transit (where she holds the rank of General) and the short story Excalibur of Mars in the Bernice Summerfield anthology Present Danger.

In the IDW comic The Forgotten, the Ninth Doctor used the name "Brigadier Bambera" as an alias when visiting World War I.

She reunited with the Seventh Doctor and Ace in the Big Finish Productions Lost Stories audio Animal.

The Doctor[edit]

See also Dr John Smith, below

UNIT's principal scientific advisor since his third incarnation was exiled to Earth (having periodically collaborated with UNIT during his second incarnation)[3] 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,[4] leaving a space-time telegraph[5] (and, later, the TARDIS' telephone number)[6] with which he could be summoned in emergencies. He retained his credentials, still bearing his third incarnation's portrait;[7] 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.[8]

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.[9]

Sergeant Duffy[edit]

Sergeant Duffy was a senior member of the UNIT platoon that arrested the Doctor and Sarah Jane Smith after their return to London in the Invasion of the Dinosaurs.

Major Frost[edit]

Major Frost was a high-ranking United States military officer called to 10 Downing Street during the crisis surrounding the appearance of aliens in London, seen in Ninth Doctor episode "Aliens of London" (2005), owing to her expertise regarding aliens. She was killed alongside her colleagues, fellow experts, by the Slitheen, electrocuted by devices planted on their nametags. Only the Doctor survives. 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.


Jo Grant[edit]

Main article: Jo Grant

Jo Grant was a civilian employee of UNIT who was assigned as assistant to the Scientific Advisor, the Third Doctor. The character appears from the serial Terror of the Autons in 1971 until The Green Death in 1973.

It is shown at that time that UNIT still knew how to reach her thirty-seven years later, and invited her to their Snowdon base for the purported funeral of the Doctor.

Private Steve Gray[edit]

Private Gray played by Wesley Theobald codename "Greyhound 16", was present during the investigation of the ATMOS corporation in The Sontaran Stratagem (2008). After stumbling across a Sontaran cloning laboratory, both he and Private Carl Harris had their minds altered to obey only the Sontarans, and were sent back into UNIT as double agents. He was described by the Sontaran leader General Staal as smelling of sweat and fear. Once the Sontarans had arrived on Earth attacking in force, he and Harris reported to Commander Skorr for duty – and were casually gunned down.


Grimshaw was a UNIT soldier saved by Sarah Jane Smith, in the Fourth Doctor serial Robot (1975).

He led the UNIT operation into the ATMOS facility and teamed up with Private Gray to secure the basement of the factory where they stumble across a cloning tank (complete with embryonic Clone) and the Sontaran leader General Staal. Staal was impressed with Harris's courage, and declared him an "above average soldier" before disparaging Harris' heightist jokes against him and brainwashing Harris to act as a double agent for the Sontarans. He set about capturing Martha Jones and assisting Commander Skorr with her cloning and then commandeering the TARDIS. Still hypnotised, he and Gray later reported to Skorr to fight alongside the Sontarans but were casually gunned down (although their deaths were never shown on screen).

She reported that the Sycorax signal came from 5000 miles above the Earth, not from Mars, which led to the realisation that there was a ship in orbit. She had A+ blood, which meant she succumbed to the Sycorax mind control. As a result of this, she stood 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.

Brigadier Alistair Gordon Lethbridge-Stewart (later Sir Alistair Gordon Lethbridge-Stewart) was a founder of UNIT and the original commander of UNIT's British contingent. During the Doctor's exile on Earth, he hired the Doctor as his Scientific Advisor. He was the father of the Doctor's (and possibly his own) eventual successor, Kate Lethbridge-Stewart. As Doctor Who show-runner Steven Moffat noted, "Out of all the people the Doctor has met, in all of space and time, Nicholas Courtney’s Brigadier Alistair Gordon Lethbridge-Stewart was the only one who was ever his boss."

Kate Lethbridge-Stewart[edit]


Colonel Mace[edit]

Doctor Who character
Colonel A. Mace
Affiliated UNIT
Species Human
Home planet Earth
Home era 21st century
Appears in "The Sontaran Stratagem" / "The Poison Sky"
Portrayed by Rupert Holliday-Evans

Colonel Mace is the commanding officer of a large contingent of UNIT (the Unified Intelligence Taskforce) in 2009. Mace first appeared in "The Sontaran Stratagem" / "The Poison Sky" (2008). He originally seemed to view the Doctor as a superior officer, saluting him and taking his orders; however, the two clashed and Mace began 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 agreed 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 organised the troops for an assault on a Sontaran position, telling the Doctor he wasn't listening any more, and rallied 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.

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.

In the Torchwood serial Children of Earth, John Frobisher and Colonel Oduya discuss Mace's posting in Vancouver. However, as this conversation is a swift change of subject to avoid classified information being heard by Lois Habiba, it is not clear if there is any truth in it. There was also a reference to Colonel Mace's posting in Vancouver in the Eleventh Doctor story The Forgotten Army.

Captain Erisa Magambo[edit]

Doctor Who character

First appearance "Turn Left"
Last appearance "Planet of the Dead"
Portrayed by Noma Dumezweni

Captain Erisa Magambo was the UNIT officer in Donna Noble's parallel universe, working with Rose Tyler to restore the correct universe in the 2008 episode "Turn Left". Her UNIT team helped construct a time machine from the TARDIS to send Donna back into the past.

Magambo returned in the 2009 episode "Planet of the Dead", this time on non-parallel Earth, as a senior officer of a UNIT patrol. She was leading 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 aided the Doctor's attempt to return to planet Earth from the Earth side of the wormhole, however when the Doctor refused to give full details of the impending Swarm she considered shutting the wormhole down to save the planet. Malcolm refused to shut the wormhole without the Doctor coming back through and resisted 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 led her troops in destroying the three Swarm aliens that came 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 commented on having to clear up the mess, to which the Doctor refused to help in the paperwork.


McGilliop, played by Jonjo O'Neill in "The Day of the Doctor", is a scientist with UNIT. The Doctor has his mobile number, and his phone is likewise capable of confirming the Doctor is the one calling. This, his access to the Black Archive, and his apparent authority to cause the large painting "Gallifrey Falls No More" to be immediately whisked away to the Tower imply a fair degree of seniority. He, like Kate Stewart and Osgood, was impersonated by a Zygon.

Captain Jimmy Munro[edit]

Captain Jimmy Munro, played by John Breslin, was Brigadier Lethbridge-Stewart's captain during the first Nestene invasion of Earth, as seen in Third Doctor serial Spearhead from Space (1970).

He met with the Prime Minister as well as the interview with the 456 and, along with UNIT soldiers, witnessed the latter's death.

Sergeant Osgood[edit]

Sergeant Osgood, played by Alec Linstead, served in Devil's End as UNIT's Technical Adviser, during the Master's interference there, as seen in the Third Doctor story The Dæmons (1971).

Steven Moffat revealed that he is also the father of Osgood as played by Ingrid Oliver


Osgood, played by Ingrid Oliver, is a UNIT scientist and assistant to Kate Stewart in "The Day of the Doctor". She wears a long, knitted scarf of many colours, reminiscent of the Fourth Doctor's scarf, and suffers from a respiratory ailment for which she uses an inhaler when over-excited. She was once impersonated by a Zygon. In the episode "Death in Heaven" she wears a bow tie reminiscent of the Eleventh Doctor and Converse trainers reminiscent of the Tenth Doctor as a tribute to both incarnations, whom she met and was influenced by in "The Day of the Doctor". She was 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 was disintegrated by Missy in the "Death in Heaven". Osgood displayed a great deal of self-control as she near-calmly tried persauding Missy to spare her with logical explanations. Her death seemed to affect the Doctor greatly.


Corporal Palmer[edit]

Corporal Palmer, played by Denys Palmer, fought against Omega's Gel Guards in the Third Doctor serial The Three Doctors (1973). This may be the same character as the Corporal named in the novelisation of Terror of the Zygons, according to The Universal Databank by Jean-Marc Lofficier.

He also entrusted her with one of five Osterhagen Keys for use in case that search failed. Following Martha's escape it was heavily implied that he was exterminated by the Daleks. His right-sleeve shoulder patch shows that he formerly served in a combat theatre with the 82nd Airborne Division.

Years later, a photograph of the late LTG Sanchez with Dr Jones hangs on a bulletin board in UNIT's black archives in the Tower of London during the tenure of Kate [Lethbridge]-Stewart as Chief Scientific Advisor.[9]

Dr. John Smith[edit]

Dr. John Smith is an alias of the Doctor, and the name used on his UNIT credentials. Second Doctor companion Jamie McCrimmon devised the alias when looking at a piece of medical equipment manufactured by John Smith & Associates while answering medical questions aboard the Wheel, circa 2050,[11] unaware that the First Doctor had already used the alias in 1963 when joining the Shoreditch Public Library;[12] Chang Lee similarly devised the same alias independently when paramedics treated the unconscious Seventh Doctor.[13] When Brigadier Lethbridge-Stewart hired the Third Doctor as his scientific adviser, the former insisted upon a name other than "the Doctor" for the latter's credentials; the Doctor told him to use "John Smith".[14] He was introduced by that name to companion Sarah Jane Smith who was then posing as her aunt, Dr. Lavinia Smith.[15] He last used the name for UNIT purposes during his seventh incarnation when he presented his old credentials to Brigadier Bambera,[7] but continued to use for other purposes; the Tenth Doctor was posing as a school teacher with that name when reunited with Sarah Jane.[16] UNIT personnel were most recently seen referring to the Doctor as "Dr John Smith" in the direct-to-video release, Auton.[17]

Portrayed by Beverley Cressman
Jemma Redgrave

Like Professor Arthur Candy and Luna University,[18] Kate Stewart or Kate Lethbridge-Stewart (her birth name is mentioned by the Doctor in "The Power of Three" and he addresses her as such in "The Day of the Doctor" and credited as such in Death In Heaven, and is called "Tiger" by her father[19]) originated in spin-off media. Kate was introduced in the home video release, Downtime (1995), in which she was the estranged daughter of retired Brigadier Lethbridge-Stewart and single mother of the young Gordon Lethbridge-Stewart; the family reunited at the end of that film. She took a more active role in defending the Earth from alien forces in the sequel, Dæmos Rising in which she starred. Kate first appeared on Doctor Who in the 2012 Eleventh Doctor story "The Power of Three" as UNIT's Head of Scientific Research. She had dropped Lethbridge when joining UNIT so as to avoid the appearance of nepotism and to be judged on her own merits. Nevertheless, her father had mentored her until his death in early 2011, and always taught her that "science leads" - a motto he had attributed to the Doctor. This motto eventually culminated with her directorship of UNIT and the radio call-sign "Greyhound Leader",[20] previously held by her father, Brigadier Winifred Bambera,[7] and Lockwood.[21] After becoming acquainted with the Eleventh Doctor, she assigns the TARDIS' materialisation sound as the Doctor's ringtone on her mobile.[22]

Kate is portrayed by Beverley Cressman in Downtime and Dæmos Rising, and by Jemma Redgrave in "The Power of Three", "The Day of the Doctor" and "Death in Heaven" (in which she is saved by a Cyberman reincarnation of her father). Each actress also portrayed an alien who disguised itself as Kate.[23]

Kate makes the third on-screen reference to the inconsistency of dates in the UNIT stories in "The Day of the Doctor" when she orders the Cromer incident record to be pulled from her late father's archives, and states that it will be filed under "70s or 80s, depending on the dating protocol."[24]
