Deletion

Deletion was what the Cybermen of Pete's World termed the killing of all those they deemed incompatible for the upgrade to cyber-form. The primary instruments of deletion were the hands of the cyber-suits, which were capable of transmitting a fatal electric shock to humans, (TV: Rise of the Cybermen/The Age of Steel) and projectile weaponry such as cyber wrist blaster or energy blasters. (TV: Army of Ghosts/Doomsday) In N-Space, Cybermen of N-Space used eradication. (TV: Silver Nemesis)

Deletion was similar to the creed of extermination followed by the Daleks, who the Cybermen engaged during the Battle of Canary Wharf. (TV: Doomsday)
