Editing Covenant Citadel

The '''citadel''', sometimes known as '''occupation citadel'''{{Ref/Book|Id=enc22p301|Enc22|Page=301}} or a '''forward operations citadel''',{{Ref/Book|Id=enc22p223|Enc22|Page=223}} is a [[Covenant]] [[Socket Base|base structure]], and the Covenant equivalent of the [[Firebase|UNSC Firebase]].{{Ref/Site|Id=hwsite|URL=http://www.halowars.com/GameInfo/Citadel.aspx|Site=Official Halo Wars Community Site|Page=Citadel|D=18|M=11|Y=2010|LocalArchive=Archive:Halowars.com/Covenant#Citadel}} It contains a command center, [[seven]] modular building sites, and four turret foundations.

== Overview ==

The citadel is a basic command structure deployed during interplanetary warfare or occupation campaigns. The citadel provides field command facilities for the commander of invading or defending Covenant forces to issue orders; it employs a modular system to build structures that support aggressive colonization as well as rapid deployment of troops and armor. Whereas UNSC Firebases and [[Banished Outpost]]s are prefabricated and airlifted into the battlefield large transport craft such as the [[D20 Heron]], [[D81-LRT Condor]] or [[Lich]], Covenant citadels and their supporting sub-structures are [[Teleporter|teleported]] into the battlefield whole. From here, supplies are driven into the base via [[gravity lift]] and stored in the Warehouses.{{Ref/Reuse|hwsite}} Once established, a large gravity lift is established in the front of the base, which can be used to move troops and vehicles to the front lines of the battle. The citadel does not appear to have any physical openings for which to enter or exit the base—troops simply use teleporters to enter and exit the base. When threatened, the base can lock down, which will establish a shield around the teleporter into the base to prevent unauthorised entry or exit into or out of the base.

The Covenant also made use of Minibases, smaller outposts only capable of supporting one additional structure. They were notably employed during the Battle of the Trove, where they were used as forward airbases with which to construct {{Pattern|Oghal|Banshee}}s and {{Pattern|Bkowe'nei|Vampire}}s.{{Ref/Level|Id=beachhead|HW|Beachhead (Halo Wars level)|Beachhead}} Unlike their UNSC [[Firebase#Minibase|counterpart]], there is no structure for the building of the Covenant minibase to attach to; simply a teleporter pad on the ground for troops and supplies to use to enter the lone building.

=== Expansions ===

The citadel is capable of hosting up to seven modular structures, alongside up to four turret slots.

Covenant citadels were employed by the Covenant during several battles in [[2531]]. One was employed during the [[Harvest campaign]], in which it was used to defend the [[Relic (location)|relic]].{{Ref/Level|HW|Relic Approach}} Several were later used in the [[Battle for Arcadia]]; one was deployed in [[Pirth City]] to defend a {{Pattern|Emp'seam|Antlion}} that was shelling the city,{{Ref/Level|HW|Arcadia City}} while another was deployed in the city's outskirts.{{Ref/Level|HW|Arcadia Outskirts}} Several citadels and minibases were deployed under the protection of a massive Covenant [[Energy shielding|dome]], though they would eventually be destroyed by an [[Orbital bombardment]].{{Ref/Level|HW|Dome of Light}} The Covenant also made extensive use of citadels during the [[Battle of Trove]]; UNSC forces from the {{UNSCShip|Spirit of Fire}} destroyed four citadels to establish a stronger foothold on the surface.{{Ref/Reuse|beachhead}}

At some point before the [[Battle of Line Installation 1-4]] in [[2552]], [[SPARTAN-II program|Spartan-II]] [[Black Team]] destroyed a citadel.{{Ref/Comic|HBL|Issue=5}} Shortly following the end of the Human-Covenant War, a citadel being used as an airbase on the swamp-moon of [[Kostroda]] by shipmaster [[Let 'Volir]] would be attacked by [[Atriox]] and his Banished forces.{{Ref/Comic|RoA|Issue=4}}

== In-game information ==

===''Halo Wars''===

In ''[[Halo Wars]]'', a default Outpost costs {{HWResources|500}} [[Supplies|resources]] to be built, and only provides three construction slots and no turret foundations. A gravity lift is automatically placed at the front of the base; units (other than the Scarab) can be sent to the gravity lift which transports them to the Leader unit's location. The gravity lift can also be used to recall the Leader unit to the base instantaneously for the cost of {{HWResources|100}}.

 

*The '''Keep''' is an upgraded version of the Firebase, retaining the command center, but adding two more building sites (for a total of five) and four turret foundations.

*The '''Citadel''' upgrade allows two other building sites, totaling to [[seven]] building sites and the same four turret sites from the station. It also features a self-destruct sequence allowing it to destroy itself for other allies to make a base in its spot and damage any enemy units nearby. The Citadel also allows for a lock sequence that will not allow any newly trained units to leave the base when done training/being produced.
