Covenant ranks
From Halopedia, the Halo wiki
I'm guessing the covanant ranks go something like this...
A hierarch.
Prophet councilers.
Legit Prophets.
Elite councilers (sorry I guess I lost the image)
Engineers
Honor Guard Elite
Zeilot
Ultra Elite
Spec Ops Elite
stealth
Major Elite
Ranger
And minor Elite Next the brute Cheiftain
Honer guard brute
Captain
Brute major
Brute minor
Drones
Hunters
Spec Ops Grunt
Gunner grunt
Grunt veterin
Grunt minors Jackal snipers
Jackal ranger
Jackal majors
Jackal minors
So I guess thats how the cast system works
