Soldier (Planet of the Spiders)

This Soldier was a UNIT soldier and technical officer under Brigadier Lethbridge-Stewart. While conducting maintenance upon the Third Doctor's new vehicle in UNIT HQ's carpark, he was approached by Lupton, who askedthe soldier the whereabouts of the Doctor. After an initial misunderstanding concerning the base's medical officer, he told the man the Doctor would be in his laboratory at this time of day. Having cleared that up, the Soldier requested a security pass from Lupton. Lupton attacked him with his advanced psychic powers and the soldier was left for dead in the carpark.

Behind the scenes

 * The Soldier was played by Pat Gorman, who played a UNIT Soldier in The Three Doctors (uncredited) and a UNIT Corporal in Invasion of the Dinosaurs. It is not unreasonable to assume that these three characters are one and the same.
