The Rookie is a Lance Corporal in the UNSC Marine Corps. He is an Orbital Drop Shock Trooper who served in Mombasa, Kenya in 2552 and is a part of the Captain's squad. The Rookie is the only known survivor of his unit after the Prophet of Regret's slipspace jump devastated the city when ODSTs were still conducting the drop.

Background
After the devastation of Regret's jump to slipspace above the city, the ODST was the only known survivor of his unit to land, with a 99.99% expected fatality rate (later corrected to 00.52%), having only battered armor and a 6 hour period of being unconscious to show for it. At the time of impact, the Superintendent displayed the message "Motor Vehicle Crash!" and when searching for the debris through the smoke, the SI attempted to acquire the HEV's vehicle ID. As a Civilian Infrastructure AI it would not have known what a HEV pod is and assumed it was a vehicle. This argument is further supported when the Superintendent attempts to obtain a vehicle I.D. for the Type-52 Phantom that came searching for survivors of the ODST drop. As a result of failing to identify the alien ship it then called the New Mombasa Police Department. After blowing the hatch off his pod and making sure it was clear, the Rookie stayed in the shadows to avoid the probing lights of the Phantom, and a patrolling Jiralhanae pack which had a sense that he was there but decided to move on thinking it was just debris. The Superintendent activated a set of signs and lights a row of warning arrows, showing the Rookie a safe path away from the patrol, and advising him to use caution on the road ahead.
