Cyber-Scout

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

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

History
On Telos, Scouts usually patrolled a set route. They were targeted by Stratton and Bates. (TV: Attack of the Cybermen)

A Cyber-Scout was time scooped to the Death Zone by Borusa, 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)
