SPARTAN-IV program

The SPARTAN-IV Program is the fourth iteration of the SPARTAN supersoldier program. It was conceived by Admiral Margaret Parangosky, the Commander-in-Chief of the Office of Naval Intelligence.

Background
Commissioned as a result of the success of the preceding SPARTAN-II and SPARTAN-III projects, the SPARTAN-IV Program was originally to be headed by SPARTAN-III lead Colonel James Ackerson, with SPARTAN-II project lead Dr. Catherine Halsey to be reassigned as Ackerson's subordinate. Ackerson was killed following the Battle of Mare Erythraeum and Halsey was arrested after returning from Onyx, though ONI continued the program without the two.

Like the original ORION Project, the SPARTAN-IV Program utilizes consenting adult volunteers selected from the other branches of the UNSC Defense Force. The remaining SPARTAN-IIIs and SPARTAN-IIs that survived the war were offered to be integrated into the SPARTAN-IV Program. An unknown number of SPARTAN-IVs were active by 2553. Some of them, including Majestic Squad, were assigned to the before it was launched. They trained with one another on the Infinity 's state-of-the art combat deck (a training chamber that is capable of replicating environments), in order to constantly stay battle-ready.

The SPARTAN-IVs serve in a dedicated branch of the UNSCDF known simply as "Spartan", whereas their forebears operated within other chains of command. Unlike their predecessors, the SPARTAN-IVs are identified by their surnames rather than numeric tags.
