Dalek Section Leader

Dalek Section Leaders were Daleks in charge for scientific researches and Dalek operations on many planets the Daleks conquered.

History
The original Dalek hierarchy established by the Dalek Prime designated Red Daleks as section leaders. (PROSE: The History of the Daleks)

The Dalek Survival Guide identified the black-domed Silver Daleks active in the Human Factor Incident as "section leader Daleks". (PROSE: Dalek Survival Guide) The Emperor himself designated them as Black Dalek Leaders. (TV: The Evil of the Daleks) Other accounts identified them as Elite Guard Daleks or Imperial Guard Daleks. (PROSE: Prisoner of the Daleks, Birth of a Legend, AUDIO: Order of the Daleks)

A grey Section Leader was tasked on Spiridon to experiment invisibility before it was killed by a Dalek Supreme for failing to meet its mission's objectives. (TV: Planet of the Daleks) A Dalek Section Leader was present on the planet Galacton. (PROSE: [[Mission to Galacton (short story)|Mission to Galacton)
