John Benton

John Benton was a member of UNIT during the Third Doctor's exile on Earth and after. He was promoted from Corporal to the rank of Warrant Officer Class 1, holding the post of Regimental Sergeant Major. One source says that he later achieved the rank of Lieutenant.

Early life
John Benton's grandfather met the Ninth Doctor and Rose Tyler in the trenches of World War I in 1914. (IDW: The Forgotten) Likewise, John Benton's father also served in the military. As a boy, John looked up to him and wanted to be just like him. His brother, Chris Benton, did not want to be a soldier. (RP: Wartime)

In 1944, while his father was on embarkation leave, the Benton family had a picnic in the woods outside Bolton. While the boys played, Chris fell from a tower to his death. John tried to save him but failed and blamed himself ever after. Some time later, his father was killed in Normandy by a grenade. (RP: Wartime)

John Benton also had a younger sister (DW: The Android Invasion). He also had an auntie, who was implied to be a medium and died in the late-1960s. (MA: The Eye of the Giant)

Military career
Benton met the Doctor for the first time while he was a Corporal, though he was initially doing surveillance work rather than serving in uniform. He helped the Second Doctor against the Cybermen and Tobias Vaughn. (DW: The Invasion)

By the time of the Doctor's regeneration and exile, Benton had been promoted to Sergeant. He quickly formed a close working relationship with the Third Doctor, Captain Mike Yates and Brigadier Lethbridge-Stewart. Lethbridge-Stewart, in fact, often called Benton rather than Yates when an order needed to be carried out.

Benton was always a down-to-earth British infantryman and non-commissioned officer - reliable, uncomplicated and with a good dose of common sense. When the Doctor asked him if he was going to comment that his TARDIS was bigger on the inside than on the outside as everyone did, Benton's classic reply was, "Well, that's pretty obvious, isn't it?" (DW: The Three Doctors) Despite not understanding what the Doctor was doing or any of his explanations, Benton always took the Doctor at his word and trusted him implicitly. Benton was loyal, not just to the rank but also to the people he worked with and was willing to disobey orders when necessary to help them. (DW: Invasion of the Dinosaurs)

Little, though, is known of his personal life at this time. It seems Benton was single and preparing for a dancing date with his sister when a crisis with Azal interrupted his plans. (DW: The Dæmons) He flirted briefly with Jo Grant and Sarah Jane Smith, though as far as is known, this never progressed beyond good-natured banter.

Benton had some memorable experiences in UNIT. He fought Daleks and Ogrons from an alternate timeline. (DW: Day of the Daleks) The Master's TOMTIT machine regressed him to a baby. When restored to adult form, he appeared before his UNIT colleagues stark naked. (DW: The Time Monster) Benton also worked alongside both the current Doctor and the Doctor's previous incarnation, whom the Time Lords had called in to help against Omega. Benton was delighted with the reunion. (DW: The Three Doctors)

Shortly before the return of the Doctor to Earth and his regeneration into his fourth incarnation, Benton was promoted to Warrant Officer. (DW: Robot) As a Regimental Sergeant Major, Benton helped against the Zygons. (DW: Terror of the Zygons) He was stationed at the Space Defence Station at Devesham during the Kraals' attempted invasion of Earth, where he was replaced by one of Styggron's android duplicates. (DW: The Android Invasion)

While transporting radioactive cargo through the woods outside Bolton with Private Willis, Benton was haunted by the ghosts of his brother and father. He overcame his feelings of guilt (which were apparently the source of these hauntings) and returned to his post in time to prevent the cargo from being hijacked. (RP: Wartime)

Life after UNIT
In 1979, Benton had left UNIT and become a used car salesman. (DW: Mawdryn Undead) Some time later he was married and had three children. (EDA: Genocide)

In 2010 he attended the wedding of Bernice Summerfield and Jason Kane. By this time he was in his seventies, well-tanned and stocky. (NA: Happy Endings)

Apocryphal information
One alternative account states that by 1986, Benton had returned to UNIT and become a commissioned officer with the rank of Lieutenant, subsequently leading a UNIT team to Antarctica to clear up the chaos left by the Cybermen's attempt to drain Earth of its energy. (DWN: The Power of the Daleks)

Behind the scenes

 * Benton would have appeared in a cameo in DW: The Five Doctors, not recognising the Second Doctor and denying him admittance to UNIT's reunion. However John Levene declined to take up the role again on the grounds that Benton would have remembered that version of the Doctor and not made such a mistake. Instead, he was replaced by the character of Colonel Charles Crichton.
 * During his onscreen appearances, Benton's first name was never given. It was first revealed in BBV: Wartime, but it appeared in later, fully-licensed work, such as NA: Happy Endings.
