Cyber-Scout

Cyber-Scouts, also known as Cyber-Troopers, were a division of Cybermen that were specialised for reconnaissance.

On Mondas, Cyber-Scouts operated Cyber-Scout craft. (COMIC: The Dead Heart, The Prodigal Returns)

Some Cyber-Scouts were painted to best camouflage with their environment. A number of Neomorph Cyber-Scouts that patrolled the London Underground were painted black, making them nearly invisible in the dark tunnels. (TV: Attack of the Cybermen)

On Mondas
A Cyber-Scout was sent in a Cyber-Scout craft on a mission to find the Lizard Kings. Crashing in a jungle, the scout encountered a village of human Mondasians, who believed it to be a servant of the gods. Raven, a heretic, was selected by their religious leader to accompany the scout on its mission to find the Lizard Kings. At the edge of the Blisterlands, they encountered a cybernetic dinosaur which conveyed them to the Dead Heart of the World, an underground base. Inside, they revived Kho'dja, an augmented Lizard King, who told them the history of Mondas. The Cyberman killed Kho-Dja, declared that Mondas would belong to the Cyber-race, and had Raven placed in a conversion unit. (COMIC: The Dead Heart)

Manning a Cyber-Scout craft, a Cyber-Scout was sent on a mission to travel through a cosmic cloud that appeared the same time an ape-servant had arrived, to find the ape's home planet and convert their species. The Cyberman came through the cloud and was fired at by missiles by the Lizard Kings on Mondas, in an era before Mondas broke away from Earth. The missiles missed the Cyber-Scout craft, but the recoil injured it and damaged its voicebox. Noticing the Cyberman's technology was not unlike their own, the Lizard Kings decided to study the Cyber-Scout through vivisection and sent an ape-servant into the cloud to its world. The ape-servant inside the craft was the same ape that inspired the Cybermen to send the Cyber-Scout through the cosmic cloud in Mondas' future. (COMIC: The Prodigal Returns)

Later history
On Telos, Neomorph Cyber-Scouts usually patrolled a set route. They were targeted by Stratton and Bates. Other Cyber-Scouts travelled back with the Cyber-Leader in a failed effort to avert the destruction of Mondas. (TV: Attack of the Cybermen)

A Cyber-Scout was Time Scooped to the Death Zone by, where it was used to locate the Doctors, as the Cybermen planned to find the Doctor's TARDIS and destroy it with Cyber-bombs. (TV: The Five Doctors)
