A master-pack is a Jiralhanae organization far above the level of pack. Incorporating a large number of smaller packs, and likely organized under Alpha Tribes, it is likely that master-packs are more of a political body than an actual military organization, with packs serving as the military branches. It is also possible that master-packs are as to packs much like divisions are to companies.

Prior to the Jiralhanae's discovery by the Covenant, rival master-packs had waged widespread mechanized warfare against each other across the surface of Doisac, causing such destruction that it reduced their species to a pre-industrial state.
