Parker

Sergeant Parker was a non-commissioned officer in the UNSC Marine Corps and an Orbital Drop Shock Trooper. Sergeant Parker was stationed aboard the as part of the ODST detachment under First Lieutenant Melissa McKay in September 2552 during the Battle of Installation 04.

Battle of Installation 04
Like most of his comrades, Sergeant Parker abandoned the Autumn when it was attacked by the Covenant over Installation 04 using an SOEIV to drop down to the surface of the ring. He then assisted in the attack on the mesa that would be Alpha Base.

Later, he led the ODST attachment that accompanied SPARTAN John-117 on the mission to rescue Captain Jacob Keyes, who was held prisoner aboard the Truth and Reconciliation. After being deployed beneath the ship via Pelican Echo 419, Parker and his ODSTs assisted the Master Chief; John felt that the ODSTs slowed him down because they did not have the reflexes and combat skill Spartans had.

Parker was wounded by the spines of an Mgalekgolo in the vessel's cargo bay. Nevertheless, he shrugged off his wound and continued to lead the attack, liberating Captain Keyes from the brig of the vessel.

He was an efficient, personable leader. He was also very duty-minded, as he continued to fight even after sustaining a serious wound. He was noted to have teased the Master Chief, whom he treated with more respect than most ODSTs.
