Brigadier
Brigadier, also called brigadier general, was a military rank on Earth.
The Doctor's good friend and companion, Alistair Gordon Lethbridge-Stewart, was often referred to by this rank. Having first met him as a Colonel, (TV: The Web of Fear) the next time the Second Doctor met Alistair Gordon Lethbridge-Stewart, he had been promoted to Brigadier and made head of the United Kingdom branch of the newly formed UNIT. (TV: The Invasion) Though promoted to General decades later, (PROSE: The Dying Days) his friends and colleagues, such as the Doctor and Sarah Jane Smith, would continue to refer to him as "the Brigadier" (TV: The Poison Sky) or "the Brig" (TV: Revenge of the Slitheen) as he was commonly known. Lethbridge-Stewart himself, despite attaining the rank of Commander of the Most Excellent Order of the British Empire, prefered to go by Brigadier for "sentimental reasons". (PROSE: The Two Brigadiers) In 2009, he introduced himself as "Brigadier Sir Alistair Gordon Lethbridge-Stewart". (TV: Enemy of the Bane)
A later UNIT leader also held the same rank, Brigadier Winifred Bambera. (TV: Battlefield)
In 2000, William Bishop was promoted to Brigadier. (PROSE: The Two Brigadiers)
