List of UNIT personnel
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.
Corporal Adams, played by Max Faulkner, is stationed in Devesham during the Kraal invasion, as seen in the Fourth Doctor serial The Android Invasion (1975). The Kraals make an android replica of him. Faulkner had previously played a UNIT Soldier in the Third Doctor serial The Ambassadors of Death (1970).
Colonel Ahmed (played by Sanjeev Baskhar) is a senior UNIT officer who is seen serving during the crisis when the Earth's dead are reconstituted as Cybermen, as seen in "Death in Heaven" (2014). He serves aboard the presidential aircraft Boat One, and is killed when the Cybermen destroys the aircraft.
Atkins, played by Tom Keller, is a UNIT commissionaire who guards the entrance to the Black Archive in the dungeons below the Tower of London. The Archive's 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 is his first. He is seen in "The Day of the Doctor" (2013).
Brigadier Winifred Bambera
|Brigadier Winifred Bambera|
|Doctor Who character|
|Home era||20th century|
|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 works alongside the Seventh Doctor, Ace and Brigadier Lethbridge-Stewart in defeating the extra-dimensional forces of Morgaine and Mordred in Carbury. She is in command during the mid-1990s and is tasked with transporting a nuclear missile across Britain. Bambera is shown able to fight with weapons and in hand-to-hand combat. She takes a no-nonsense, by-the-book approach to command that warrants the respect of those under her. Major Husak and Sergeant Zbrigniev reports 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 (1995) and The Dying Days. It is revealed that she has 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 (1996). 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 (2010).

Major Richard Blake
|Major Richard Blake|
|Doctor Who character|
|Home era||21st century|
|Appears in||"The Christmas Invasion"|
|Portrayed by||Chu Omambala|
Major Richard Blake works at UNIT during "The Christmas Invasion" (2005). He contacts the Torchwood Institute on the orders of Prime Minister Harriet Jones. Having been transported to their ship, he is killed by the Sycorax for protesting about them killing Daniel Llewellyn, the Project Director for the Guinevere One space probe.
Private Bryson, played by Colin Bell, is on duty during the supposed 'Dinosaur Invasion', as seen in the Third Doctor serial Invasion of the Dinosaurs (1974). Somewhat gullible, he holds the Doctor captive after his arrest, but gets sent away by Sergeant Benton to get rope to tie the Doctor up, allowing Benton to prompt the Doctor to escape.
Six unnamed corporals have appeared in the series, played by Billy Horrigan, (The Mind of Evil, 1971), Clinton Morris and Derek Martin (The Claws of Axos, 1971), Patrick Milner (The Dæmons, 1971), Pat Gorman (Invasion of the Dinosaurs, 1974) and Bernard G. High (Terror of the Zygons, 1975, the novelisation of which calls him Palmer).
Colonel Charles Crichton
Colonel Charles Crichton played by David Savile, succeeds Brigadier Lethbridge-Stewart as Brigadier following the latter's retirement. He briefly meets the Second Doctor during a UNIT reunion, featured in The Five Doctors (1983), at which Lethbridge-Stewart is also present. The Doctor brands him as "unpromising". He later becomes the deputy director of The Forge.
UNIT's principal scientific advisor since his third incarnation was exiled to Earth (having periodically collaborated with UNIT during his second incarnation) the Doctor has maintained a loose affiliation with UNIT in all[dubious ] his subsequent bodies. The Doctor departed from UNIT's full-time employ during his fourth incarnation, leaving a space-time telegraph (and, later, the TARDIS' telephone number) with which he could be summoned in emergencies. He retains his credentials, still bearing his third incarnation's portrait; 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."
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.
Bill Filer, played by Paul Grist, is an American intelligence agent sent to liaise with UNIT about the Master. Kidnapped and duplicated by Axos, he manages to escape and help the Doctor and UNIT defeat Axos, in the Third Doctor serial The Claws of Axos (1971).
Major Frost is 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 is killed alongside her colleagues, fellow experts, by the Slitheen, electrocuted by devices planted on their nametags. 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[original research?] 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 is 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. She maintained communication with her former UNIT colleagues, as discussed in Invasion of the Dinosaurs (1974), but was not seen again until 2010 when she met her old successor, Sarah Jane Smith, and the Doctor's eleventh incarnation in the Death of the Doctor serial of the spin-off series The Sarah Jane Adventures. It is shown at that time that UNIT still knows 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
Private Gray, played by Wesley Theobald, codename "Greyhound 16", is 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 have their minds altered to obey only the Sontarans, and are sent back into UNIT as double agents. He is described by the Sontaran leader General Staal as smelling of sweat and fear. Once the Sontarans had arrived on Earth attacking in force in "The Poison Sky" (2008), he and Harris report to Commander Skorr for duty – and are casually gunned down.
Dr. Oliver Harrington
Private Carl Harris
Private Carl Harris played by Clive Standen codename "Greyhound 15", has appeared in 3 episodes of Doctor Who series 4. His first appearance in "The Sontaran Stratagem" and "The Poison Sky" (2008). He leads the UNIT operation into the ATMOS facility and teams 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 is impressed with Harris' courage, and declares 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 sets 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 are casually gunned down.
He returned in the episode "Turn Left" (2008), leading a UNIT operation in a parallel universe and announcing the Tenth Doctor's death during the events of the attempted Racnoss invasion, the events of which occurred previous to the Sontaran invasion.
On Page 129 of the reference book The Time Traveller's Almanac, Harris' first name is given as Carl.
Captain Hawkins, played by Paul Darrow, fights against the Silurians before being killed by the Young Silurian when he comes to Brigadier Lethbridge-Stewart's rescue in the Third Doctor serial Doctor Who and the Silurians (1970).

Sally Jacobs, played by Anita Briem, is a technician on duty in the UNIT facility in the Tower of London during the Sycorax invasion, seen in the Tenth Doctor episode "The Christmas Invasion" (2005). She reports that the Sycorax signal came from 5000 miles above the Earth, not from Mars, which leads to the realisation that there was a ship in orbit. 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.
Private Jenkins was a UNIT soldier, serving with the task force deployed to Devil's End in the serial The Dæmons (1971). Not to be confused with the Private Jenkins who later fought the Sontarans. He was apparently a skilled marksman; responding to the Brigadier's orders, "Jenkins; the chap with wings; five rounds rapid!"
Private Ross Jenkins
Ross Jenkins, codename "Greyhound 40", appeared in the Tenth Doctor episodes "The Sontaran Stratagem" and "The Poison Sky" (2008). He was portrayed by Christian Cooke. Ross is first seen talking to another UNIT soldier when Mace orders him to take the Doctor to the Rattigan Academy. He is shot and killed by the Sontaran Commander Skorr.
Private Johnson, played by Geoffrey Beevers, was revealed to be one of Reegan's henchmen in the Third Doctor serial The Ambassadors of Death (1970). According to the Doctor Who: Missing Adventures novel The Scales of Injustice (1996) by Gary Russell, his first name is Jeff.

She contacts the Doctor so he could help UNIT in the episode "The Sontaran Stratagem" (2008). She becomes trusted enough in UNIT to be given the Osterhagen Key, part of a mechanism for a program to destroy Earth, as shown in "Journey's End" (2008). Martha resigns following the events of "Journey's End".
Colonel Tia Karim
Colonel Karim, played by Laila Rouass, appeared in The Sarah Jane Adventures story Death of the Doctor (2010). She delivers the unfortunate news to Sarah Jane Smith, that the Doctor had been killed. She is actually in conjunction with a rogue faction of the Shansheeths for the Doctor's faked funeral at the UNIT base in Snowdon; she allied with the Shansheeth, so they could take her out into the universe, beyond the tiny world she saw as a prison. She is killed when the memory weave explodes.
Flight Lieutenant Françoise Lavel
Flight Lieutenant Françoise Lavel, played by Dorota Rae, flies Brigadier Lethbridge-Stewart (Ret'd), in a UNIT helicopter from his home to Carbury, scene of the battle against the extra-dimensional forces of Morgaine and Mordred, as seen in the Seventh Doctor serial Battlefield (1989). Morgaine crashes the helicopter and captures Lavel, stealing her memories then later killing her senselessly.
Brigadier Alistair Gordon Lethbridge-Stewart
Brigadier Alistair Gordon Lethbridge-Stewart (later Sir Alistair Gordon Lethbridge-Stewart) is a founder of UNIT and the original commander of UNIT's British contingent. During the Doctor's exile on Earth, he hires the Doctor as his Scientific Advisor. He was the father of Kate Lethbridge-Stewart, another UNIT commander. As Doctor Who show-runner Steven Moffat noted,[when?] "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."
|Colonel A. Mace|
|Doctor Who character|
|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, 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.
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 (2009), John Frobisher and Colonel Oduya discuss Mace's posting in Vancouver. There is also a reference to Colonel Mace's posting in Vancouver in the Eleventh Doctor novel The Forgotten Army (2010).
Captain Erisa Magambo
|Captain Erisa Magambo|
|Doctor Who character|
|Home planet||Parallel Earth
|Home era||21st century|
|First appearance||"Turn Left"|
|Last appearance||"Planet of the Dead"|
|Portrayed by||Noma Dumezweni|
Captain Erisa Magambo is 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 helps construct a time machine from the TARDIS to send Donna back into the past.
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.
McGillop, played by Jonjo O'Neill in "The Day of the Doctor" (2013), 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. The Eleventh Doctor calls him to escort the Gallifrey Falls No More painting to the Black Archive. He, like Kate Stewart and Osgood, is impersonated by a Zygon.
Captain Jimmy Munro
Captain Jimmy Munro, played by John Breslin, is Brigadier Lethbridge-Stewart's captain during the first Nestene invasion of Earth, as seen in Third Doctor serial Spearhead from Space (1970). He cordons off Oxley Woods after the second fall of Nestene 'meteorites' and is the first to encounter the TARDIS and the Third Doctor.
Colonel Augustus Oduya, played by Charles Abomeli, appears in the Torchwood serial Children of Earth (2009). In the first part, he meets with civil servant John Frobisher to announce suspicions of an alien invasion by the 456. He correctly deduces that if UNIT had pieced the situation together, then Torchwood also must have done so as well. He meets with the Prime Minister as well as the interview with the 456 and, along with UNIT soldiers, witnesses the latter's death.
Sergeant Osgood, played by Alec Linstead, serves 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). He fights against Azal and Bok. He has the unenviable task of trying to build a device designed by the Doctor to be used against Azal. According to the Doctor Who: Missing Adventures novel The Eye of the Giant (1996) by Christopher Bulis, his first name is Tom.
Petronella Osgood (usually referred to only by last name), played by Ingrid Oliver, is a UNIT scientist and assistant to Kate Stewart in "The Day of the Doctor" (2013). 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" (2014), she wears a bow tie reminiscent of the Eleventh Doctor and Converse trainers reminiscent of the Tenth Doctor. 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.
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 her Zygon duplicate 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.
Corporal Palmer, played by Denys Palmer, fights 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.
Captain Marian Price
|Captain Marian Price|

|Portrayed by||Bridget Hodson|
Captain Marian Price first appeared in the background in "The Sontaran Stratagem" (2008) and was introduced fully in "The Poison Sky" (2008). She is in charge of monitoring systems and reports on how the planet was coping under the Sontaran gas, and controls the launching of UNIT-coordinated nuclear weaponry. After the Doctor clears the atmosphere with an atmospheric converter, she kisses Colonel Mace in excitement, only to remember herself afterward and awkwardly turns away. Like Colonel Mace she salutes the Doctor upon meeting him. Her collar dogs indicate that she is a member of the Royal Engineers.

Major-General Rutlidge, played by Edward Dentith, is a Minister responsible for supervising Brigadier Lethbridge-Stewart's UNIT operations on British soil at the Ministry of Defence and was seen in the Second Doctor serial The Invasion (1968). He is an old military school friend of the Brigadier. Tobias Vaughn takes control of his mind and uses him to prevent UNIT interfering with the Cybermen invasion of Earth. He is forced to kill himself by Vaughn, when he tried to rebel.
Lieutenant General Sanchez, played by Michael Brandon, is the American officer commanding UNIT's Manhattan base in "The Stolen Earth" (2008). His authority includes oversight of Project Indigo, and he directs Martha Jones to use the Sontaran based technology to find the Doctor. He also entrusts her with one of five Osterhagen Keys for use in case that search failed. Following Martha's escape it is heavily implied that he is 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 Archive in the Tower of London during the tenure of Kate [Lethbridge]-Stewart as Chief Scientific Officer.
Dr. Elizabeth Shaw
Originally drafted as Scientific Advisor, Dr. Elizabeth Shaw accepts the position of Assistant when the Third Doctor took the job of Scientific Advisor.
Lieutenant Shears was a UNIT officer during the serial Invasion of the Dinosaurs (1974). He commands the platoon that arrests the Doctor and Sarah Jane Smith on their return to London.
Dr. John Smith
Dr. John Smith is an alias of the Doctor, and the name used on his UNIT credentials. When Brigadier Lethbridge-Stewart hires the Third Doctor as his scientific adviser, the former insists upon a name other than "the Doctor" for the latter's credentials; the Doctor told him to use "John Smith". He is introduced by that name to companion Sarah Jane Smith who is then posing as her aunt, Dr. Lavinia Smith in the serial The Time Warrior (1973–74). He uses the name for UNIT purposes for the last time during his seventh incarnation when he presents his old credentials to Brigadier Bambera. UNIT personnel are most recently seen referring to the Doctor as "Dr John Smith" in the direct-to-video release, Auton (1997).[note 1]
Sarah Jane Smith
Sarah Jane Smith is an investigative journalist who becomes a UNIT associate by way of her companion relationship with the Third, Fourth, Tenth and Eleventh Doctors. She first gains access to UNIT in the serial The Time Warrior (1973–74) by posing as her aunt and foster mother, the famous virologist Dr. Lavinia Smith — a guise through which the Third Doctor immediately sees, as he had read papers which Lavinia published when Sarah Jane was but a young child. Sarah Jane maintains contact with, and receives support from, senior UNIT personnel well after leaving their employ.
Several unnamed soldiers have appeared in the series, played by: Max Faulkner, (The Ambassadors of Death, 1970) (Faulkner later played Corporal Adams in The Android Invasion, 1975); Les Conrad, (Terror of the Autons, 1971); Pat Gorman, (Planet of the Spiders, 1974; the novelisation of which refers to him as Corporal Hodges) (Gorman had appeared in a prior serial, Invasion of the Dinosaurs, 1974, as a UNIT Corporal); Brian Fellows (Robot, 1974–75); and Peter Symonds (Terror of the Zygons, 1975). Another soldier is seen in The Time Warrior.
|Doctor Who character|
|Home era||20th–21st centuries|
|First appearance||Downtime (spin-off)
The Power of Three
|Portrayed by||Beverley Cressman
Like Professor Arthur Candy and Luna University,[note 2] Kate Stewart or Kate Lethbridge-Stewart (her birth name is mentioned by the Doctor in "The Power of Three", 2012, and he addresses her as such in "The Day of the Doctor", 2013, and credited as such in "Death in Heaven", 2014, and is called "Tiger" by her father) originated in spin-off media. Kate is introduced in the home video release, Downtime (1995), in which she is 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 takes a more active role in defending the Earth from alien forces in the sequel, Dæmos Rising (2004), 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,[additional citation needed] and always taught her that "science leads" – a motto he had attributed to the Doctor. This motto eventually culminates with her directorship of UNIT and the radio call-sign "Greyhound Leader", previously held by her father, Brigadier Winifred Bambera, and Lockwood.
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". Each actress also portrayed an alien who disguises itself as Kate.[note 3]

He is implied to still be in UNIT's employ in "The Day of the Doctor" (2013); the Tower of London's robotic or cybernetic ravens fall under his remit.[note 4]
Field-Marshal Thatcher is based in Geneva during the Second Doctor serial The Invasion (1968). When Major-General Rutledge, under Tobias Vaughn's duress, tries to prevent UNIT from interfering with the Cybermen invasion of Earth, Brigadier Lethbridge-Stewart threatens to go over Rutledge's head, directly to Thatcher.
