R/T soldier

A R/T soldier was a UNIT soldier. When dinosaurs started to appear in London, he was a soldier who was assigned to stay behind in the city. He was on patrol when a Tyrannosaurus rex smashed through a building and trapped them. He radioed in to UNIT HQ and told them that they were being attacked by a T-rex and that bullets wouldn't stop it. They finally managed to force it back with a grenade. (TV: Invasion of the Dinosaurs)
