Staff Sergeant Nolan Byrne is an UNSC Marine, a member Project: ORION, and a possible SPARTAN-I. He was in Operation: TREBUCHET with Avery J. Johnson, until he was severely injured from an explosion. Byrne was then reassigned to the planet Harvest to train a local militia with Avery J. Johnson.

Biography
Byrne participated in Operation: TREBUCHET in 2524 leading Bravo Squad of a platoon of marines alongside Staff Sergeant Avery J. Johnson. Their squads used Hornets to jump from target to target eliminating Rebel bomb making factories. However, when a rebel was cornered in a Jim Dandy restaurant, Byrne told Johnson to fire an M99 Special Application Scoped Rifle, (A.K.A gauss-rifle), at an Insurrectionist holding a child hostage. Johnson did not, leading to the boy's father tackling the woman, and the destruction of the Jim Dandy restaurant, along with many of the Marines in Byrne's squad and thirty eight civilians.

Later, Byrne was re-assigned along with Johnson to investigate the disappearance of freighters around Harvest, but officially, he was sent to help train the Colonial Militia on the planet. He and Johnson fought four Jackals in the first battle between the UNSC and Covenant,on board the human freighter called This End Up, and they successfully defeated them. Byrne and Johnson (with the rest of the militia of harvest) were also present at the initial negotiations between the Brutes and the Humans. They also fought Tartarus, Maccabeus and several Grunts. One militia soldier was torn apart by a Grunt, which sparked the firefight. As the conflict heated up, Byrne continued to defend the planet from Covenant hostiles and he received multiple injuries in the conflict. He was fortunate enough to live through the battle, and evacuated with Johnson, Jilan al-Cygni, and the rest of the Colonial Militia in a Pod heading from the Tiara. Whether or not he participated more in the Human-Covenant War is currently unknown.
