A Sector was a generic term for a vast number of large geographic and astrographic locations.

Description[edit | edit source]

Space[edit | edit source]

Space sectors usually contain several star systems, some of which are UEG colony worlds. Other sectors contain no planets at all.

There appear to be three systems for naming sectors, one for inhabited sectors, one for uninhabited sectors. The UNSC Navy designates sectors as "FLEETCOM Sector (number)" to denote the division of command the sector's inhabitants fall under.

Other sectors are simply designated "Sector (letter)-(three numbers)". Some were given conventional names.

There were known to be at least five sectors of human space.[1]

Planetary[edit | edit source]

Locations on planets can also be designated as a Sector. Often they were named "Sector (number/numbers/letter)".
