Fleet

A Fleet is a large, permanent organization of Starships. Fleets are usually relatively large and manned by thousands of individuals on what is normally hundreds of ships. Though the size of Fleets vary, UNSC and Covenant Fleets are very different.

UNSC Fleets

UNSC Fleets are massive divisions of UNSC ships. UNSC Fleets usually consist of large numbers of Frigates and Destroyers, escorting a handful of larger Carriers and Cruisers. These Fleets also usually have a Prowler to act as the Fleet's eyes and ears and to also serve as saboteurs. Fleets are given a simple, numerical designation.

Smaller UNSC groups of ships are called Battle Groups.

Covenant Fleets

Unlike in the UNSC, Covenant Fleets are dominated by larger ships. Frigates are common in smaller Fleets, however, there are usually far more Destroyers and Cruisers. Covenant Fleets are essentially self-sustaining Armadas, capable of operating without supply for indefinite periods thanks to their use of Agricultural Support Ships. They are also given different designations, like ships.

Smaller groups of Covenant ships are called Task Forces.
