Dalek task-force

The Daleks were typically organised into task-forces, (TV: Genesis of the Daleks, Resurrection of the Daleks, Attack of the Cybermen, Remembrance of the Daleks) led by Taskforce Commanders. (AUDIO: Pretty Lies)

History
The Sixth Doctor recalled that Gustave Lytton was associated with the Dalek Task Force. (TV: Attack of the Cybermen) Indeed, Lytton, acting on behalf of the Supreme Dalek, had led a group of Dalek Troopers on the mission to retrieve Davros from the Prison Station to gain his assistance against the Movellan virus. (TV: Resurrection of the Daleks)

A Dalek Taskforce Commander, serving under the Dalek Time Strategist, led the Dalek attack on Fergil in the Last Great Time War. (AUDIO: Pretty Lies)

Behind the scenes
The term is rendered as "Dalek task-force" in the novelisations The Mutation of Time, Doctor Who and the Genesis of the Daleks and Remembrance of the Daleks, while "Dalek Task Force" is used in Attack of the Cybermen. This latter use echoes the Dalek Task Force from the feature of the same name in The Dalek World.
