SPARTAN-IV program

The SPARTAN-IV Program is the fourth generation of the SPARTAN program. It consists of members recruited from the UNSC's military, augmented to be capable of wearing a variant of the MJOLNIR armor. This phase was initiated by Admiral Margaret Parangosky after the Human-Covenant war, and some are stationed near the in the Oort Cloud.

Similar to the original ORION Project, the SPARTAN-IV Program would only consist of adult volunteers, as opposed to young children. When the Program was started, the surviving members of the previous generations were offered to be integrated into it, though it's unknown how many exactly accepted/declined. The first active SPARTAN-IVs were already deployed by 2553, as some of them were temporarily assigned to the before it was scheduled to launch.

Trivia

 * They may appear as customizable player characters in Halo 4's multiplayer.
 * The IV's appear to be wearing suits of powered armor similar to the MJOLNIR, though these cannot be used on un-augmented subjects. It's possible volunteers for the project experienced a procedure similar to CHRYSANTHEMUM.
