Ralph-103

Ralph-303 was a SPARTAN-II commando of the UNSC Naval Special Warfare Command. He later served in the UNSC Marine Corps for unknown reasons before being killed during an engagement with Covenant infantry on Harvest.

Conscription
Ralph was abducted and conscripted into the SPARTAN-II program by Dr. Catherine Halsey in 2517 when he was six years old. He and the other Spartans were taken to the planet Reach and trained by the AI Déjà and Chief Petty Officer Mendez. In 2525, he and the other candidates underwent a series of augmentations to improve their abilities. Ralph was among the ones that survived without being crippled or killed by the procedure.

Escape
A few weeks after the augmentation procedures, Ralph, along with Daisy-023, Joseph-122, and two other Spartans, rebelled against their trainers, taking them hostage and demanding that Dr. Halsey let them leave. Halsey granted them freedom, and they escaped Reach as stowaways, hoping to return home to their parents.

Later Career and Death
Through unknown means, Ralph stopped serving as a Spartan, became a Marine, and later participated in the Harvest Campaign. During an engagement with the Covenant, Daisy-023 attempted to assist him and a group of other Marines. After being mortally wounded by Needler fire, Daisy-023 unsuccessfully attempted to cover the Marines' retreat. They and Ralph were killed by a Sangheili's Fuel Rod Gun while trying to escape in a Pelican. Because Ralph became a Marine, it is possible that he was exempted from Office of Naval Intelligence Directive 930 and listed as KIA.
