UNSC rank structure

The rank structure of the United Nations Space Command's mainline branches of service (the Navy, the Marine Corps, the Army, and the Air Force) is largely derived from the system employed by the 21st century United States military. The recently-created Spartan branch is an exception to this, as its members lack conventional ranks.

Warrant Officer
A Warrant Officer is a military officer in the armed forces ranking above a non-commissioned officer (NCO) but below a commissioned officer.

The WO ranks, from lowest to highest are: Warrant Officer 1, Chief Warrant Officer 2, Chief Warrant Officer 3, Chief Warrant Officer 4, and Chief Warrant Officer 5. WO1s are made officers by warrant. Being promoted to the rank of Warrant Officer is considered a high honor for any NCO.

Trivia
The Halo Encyclopedia describes the structure and insignia of the UNSC's ranking system as being identical to those used in Halo multiplayer, Halo 3 in the original printing and Halo: Reach in the 2011 edition.
