John Benton (Silurian Earth)

Sergeant John Benton was the version of Benton who lived on the alternate Earth ruled by the Silurians.

He led an expedition to London to acquire medical supplies for Jo Grant. After her death, the Brigadier ordered him to retrieve the other half of Computer Control Related Missile Launch Protocol Manual from its hiding place in Whitehall instead. He was later killed when UNIT attacked Ophidian as a diversion so General Hobson could launch the nuclear missiles on the HMS Revenge without the Silurians interfering. (PROSE: Blood Heat)
