R/T soldier

A R/T soldier was a UNIT soldier.

Biography
When dinosaurs started to appear in London during the 1970s, the soldier was assigned to stay behind in the city.

He was on patrol when a Tyrannosaurus rex smashed through a building and trapped them. The soldier radioed in to UNIT HQ and told them that they were being attacked by a T-rex and that bullets wouldn't stop it. The patrol finally managed to force it back with a grenade.
