UNIT corporal (Invasion of the Dinosaurs)
From Tardis Wiki, the free Doctor Who reference
UNIT Corporal was the head of UNIT solders, left behind in an evacuated London to track time-displaced dinosaurs. (DW: Invasion of the Dinosaurs)
Behind the Scenes
UNIT Corporal was played by Pat Gorman, who played a UNIT Solider in The Three Doctors (uncredited) and Soldier in DW: Planet of the Spiders. It is not unreasonable to assume these three characters are one and the same.
