Holotank displaying Cortana.

The holotank, also referred to as a holo-projector, is a device used to project a hologram. A variety of different sizes and shapes of holotank exist, and the term is used to refer to both UNSC^[1] and Covenant^[2] devices. Small holotanks commonly used by AIs are often referred to as holo-pedestals.

UNSC

Holotanks are used to project a hologram of information and are sometimes reserved for 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 avatars to large tables used to display tactical information.

Covenant

The Covenant commonly use holotanks on their starships, and they are plentiful in High Charity as well. 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, 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-pedestals, to communicate over distance or in the battlefield. The Luminaries mounted on Covenant ships are typically linked to the bridge's holotank, which can display the information detected by the Luminary.^[2]
