From Halopedia, the Halo wiki
A levy was a military unit within the Covenant's military, composed of three low-ranking Unggoy soldiers. In battle, vast numbers of ill-trained levies were used for front-line combat as well as various menial roles. Levies were sometimes organized into lances under the command of a Sangheili overseer.
