Jorge was born in Pálháza on Reach on March 5, 2511, and was abducted and conscripted into the SPARTAN-II program by Dr. Catherine Halsey in 2517 when he was six years old. While on Reach, he was trained by the AI Déjà and Chief Petty Officer Mendez along with the rest of the Spartan children.
In 2525, he and the other candidates underwent a series of augmentations to improve their overall combat prowess in several different fields. Jorge was among the candidates who survived the procedure.
Fall of Reach
Jorge served with Noble Team under the call sign "Noble Five" during the Fall of Reach in 2552. He acted in the capacity of heavy weapons specialist, and was the only SPARTAN-II on the team.
Prior to the Fall of Reach, Jorge-052 along with other members of Noble Team investigated an incident over at Visegrád Relay, only to discover that Covenant forces had bypassed Reach's defenses and infiltrated key installations and communications centers. During the preliminary stages of the Covenant invasion of Reach, Jorge and Noble Team partook in multiple operations against Covenant forces on the surface of Reach, including a counter-offensive operation to retake Sword Base and a large-scale UNSC assault on a Covenant-occupied site and neutralization of a Covenant Spire.
Realizing the presence of the Covenant supercarrier after the Battle of Viery as a great threat, the team devised Operation: UPPERCUT; a tactic which involved using a YSS-1000 "Sabre" - class starfighter to deliver a makeshift slipspace bomb to the supercarrier and destroy it via a slipspace rupture. After receiving authorization from Colonel Urban Holland, the team traveled to a besieged base and assisted the UNSC forces in repelling the Covenant forces. Jorge and Noble Six boarded a Sabre and launched into space to join the Epsilon Eridani Defense Fleet.
After rendezvousing with the UNSC fleet, the Sabres helped in repelling the Covenant invasion force and escorted the Savannah in commandeering a Covenant corvette. The Savannah diverted the Corvette's fire, allowing Noble Six to infiltrate the ship's hull and allow a Pelican carrying Jorge and the bomb inside the ship. Jorge and Six then used the hijacked Corvette, which was on course toward the supercarrier to refuel, to transport the the slipspace device within range of the Supercarrier. After they had taken control of the Corvette, Jorge discovered that they were not only cut off from their Sabres, the thrusters on the Pelican were damaged during the firefight, and that in order for them to return to Reach, the SPARTANS would have to free-fall back to the planet's surface. He also found that the timing device that would have been used to activate the SFTE was also damaged, and the only alternative would be to trigger it manually.
Jorge resolved that he would stay to activate the slipspace device himself and presuming that doing so would cost him his life, he entrusted Noble Six with his dog tags before forcing Six off the Covenant Corvette. His last known words, which were to Six, were "Tell them to make it count." As Six drifted away from the ship, Jorge activated the bomb, opening a slipspace rupture that enveloped the Corvette and a large portion of the Supercarrier's mid-section, sending it into the slipstream with no way out. UPPERCUT had been a success, but at the cost of Jorge.
