A Legion is a division of many Sangheili warriors which is usually led by a high ranking officer, such as a Zealot or an Ultra.


The responsibilities and purposes of a Legion seem to vary. They are capable of performing tasks ranging from bridge-crew on starships to ground combat.[1]

The violent nature of the Elite society likely demands that Legions should be capable of engaging in varied forms of combat.

Warrior CrècheEdit

A Warrior Crèche is likely a type of Legion where newer warriors hone their combat skills before being assigned to a regular legion. Warrior crèches seem to be specifically used for ground combat, and are carried aboard Covenant Fleets should any ground actions be needed.[2]
