The Spartan Program's emblem

The <Unnamed Spartan Program> is a SPARTAN program created in 2545. The first two candidates were taken in 2546 (Jack and Scarlet). One of the many challenges the Spartans faced were Trials. At the age of 11, each one of the Spartans fought against another one. The winners were augmented and received MJOLNIR armor, and extensive training in their specialized areas.
