Dalek hierarchy

Due to their highly militaristic culture, the Daleks operatee under what is nominally a rigid hierarchy; there are often variations to it, however, depending on era and circumstance.

Figurehead

 * Dalek Emperor: the overall leader of the Dalek Empire.
 * Davros: Davros, the creator of the Daleks served as leader of the Imperial Daleks.
 * The Mentor: The creator of a faction of Daleks from another universe, who led them.

Council

 * Cult of Skaro: A council of elite Daleks created to think of imaginative strategies, previous to or during the Last Great Time War (DW: Doomsday onwards)
 * Dalek Council: A governing body under the Emperor. (REF: Doctor Who: Aliens and Enemies) In some instances, they appear to rule the Daleks in the permanent or temporary absence of an Emperor. (DW: The Daleks, Planet of the Daleks)

Commanders

 * Dalek Supreme: High-ranking generals, commanding major operations or planetary occupations. These are usually black. In the early days of the Daleks, the Supreme was the direct second-in-command to the Emperor. (The Dalek Chronicles) During the Imperial-Renegade Dalek Civil War, the Renegade Dalek faction was led by a Supreme instead of an Emperor; and in the New Dalek Empire, a Supreme Dalek took command. (DW: The Stolen Earth)
 * Dalek Supreme Controller - Red-coloured Daleks, second to the Supreme. (BFDE: "Death to the Daleks!")
 * Dalek Scientific Division - high-ranking, their needs override all other orders and concerns. (BFA: Return of the Daleks)
 * Dalek Saucer Commander
 * Blue Dalek - equivalent of non-commissioned officers (EDA: War of the Daleks)

Ordinary Daleks

 * Standard Dalek

Others

 * Special Weapons Dalek - designed solely for combat, lacking the abilities of the standard Dalek. Reviled as "the Abomination". (DW: Remembrance of the Daleks, DWM: Emperor of the Daleks)
 * Marsh Dalek - designed solely for swamp combat. (The Dalek Book)
 * Servants, mercenaries and slaves: Daleks have at times also employed slaves such as Robomen (DW: The Dalek Invasion of Earth, BFA: The Mutant Phase), and pig slaves (DW: Daleks in Manhattan/Evolution of the Daleks) or mercenaries such as Ogrons (DW: Day of the Daleks, Frontier in Space) Werelox (DWM: Doctor Who and the Dogs of Doom) and Dalek Troopers (DW: Resurrection of the Daleks).

Visual distinctions
Daleks often showed their rank via colours. In one version, gold Daleks are the highest, followed by black, red, blue and grey. (EDA: War of the Daleks)

For a time, the majority of Daleks were silvery with blue "bumps", with Saucer Commanders being partially black and Black Daleks/Dalek Supremes being full commanders. (DW: The Daleks, The Dalek Invasion of Earth)

During the Last Great Time War and in New Dalek Empire, almost the entirety of Daleks shown were of the same colour; the Dalek Supreme in the latter was marked out by being red, while Dalek Sec of the Cult of Skaro was black.

Variations of standard colours have also included white (Imperial Daleks) and gold-bronze (Time War).
