Holotank: Difference between revisions

The '''holotank''', also referred to as a '''holo-projector''', is a device used to project a [[Holography|hologram]]. A variety of different sizes and shapes of holotank exist, and the term is used to refer to both [[United Nations Space Command|UNSC]]<ref>'''[[Halo: The Fall of Reach]]''', ''page 221''</ref> and [[Covenant]]<ref name="CH">'''[[Halo: Contact Harvest]]''', "chapter 3", ''page 56''</ref> devices. Small holotanks commonly used by AIs are often referred to as '''holo-pedestals'''.

Holotanks are used to project a hologram of information and are sometimes reserved for [[Artificial intelligence|AIs]], though other information can be displayed, such as mission recordings and holo-vids. UNSC holotanks vary greatly in size and shape, ranging from small cylindrical pedestals reserved for AI [[avatar]]s to large tables used to display tactical information.

The Covenant commonly use holotanks on their starships, and they are plentiful in ''[[High Charity]]'' as well. [[Artificial intelligence|AIs]] can also access the map data from the holotank's link to the Covenant information network and give directions verbally to anyone near the holotank. During the [[Battle of High Charity|Battle of ''High Charity'']], [[Cortana]] entered one to aid [[John-117]]'s passage through the city, remaining there long after the space station was transformed into a [[Flood hive]]. The Covenant also utilize [[portable holo-pedestal]]s, to communicate over distance or in the battlefield. The [[Luminary|Luminaries]] mounted on Covenant ships are typically linked to the bridge's holotank, which can display the information detected by the Luminary.<ref name="CH"/>
