Parker

Sergeant Parker was a noncommissioned officer in the UNSC Marine Corps and a member of the Orbital Drop Shock Troopers. Sergeant Parker was stationed aboard the Pillar of Autumn as part of the ODST detatchment under First Lieutenant Melissa McKay in 2552.

Like most of his commrades, Sergeant Parker abandoned the Pillar of Autumn when it was attacked by the Covenant over Installation 04 using a Human Entry Vehicle to "Helljump" to the surface of the Installation. He then assisted in the attack on the mesa that would be Alpha Base.

Later, he led the ODST attatchment that accompanied the Master Chief on the mission to rescue Captain Keyes, who was captured aboard the Truth and Reconciliation. Parker was tough and led his men well. After the drop off from Pelican Echo 419, Parker and his ODSTs were very helpful to the Chief, but he felt that they slowed him down because they did not have the reflexes and combat skill other Spartans had.

Parker was wounded by the spines of a Hunter in the cargo bay. Nevertheless, he shrugged it off and continued to lead the attack, liberating Captain Jacob Keyes from the brig of the vessel.

In Halo: Combat Evolved, he was killed when the Chief went to get Keyes and left Parker and his squad to wait by the Control Center. When the Chief returned, the entire ODST squad lie dead on the floor, with two Active Camouflaged Elites holding Energy Swords pacing the room. However the novel said the Chief simply regrouped with him. Regardless, he died during the Battle of Installation 04, along with the rest of the ODST contingent of the Pillar of Autumn (save for Corporal Locklear).
