Halo Ranking Order

What’s the ranks in halo? Who can give orders to the Chief? Who has to follow Chief orders?

Commander Laski can, head leader Of ONI Admiral Serin Osman can.
The issue is, Master Chief do what he thinks it’s right and if this means surpass any authority he will do without hesitation

But UNSC and ONI know they can’t stop him because they need him and if they stop him some other Spartans would feel depressed or sad that the main motivation of becoming a Spartan was jailed or so
