Trivia

 * During the First Battle of Harvest, Byrne's call sign was Creeper.
 * He is most likely HEV Orbital Drop qualified given the fact he has the same training as Johnson while in NAVSPECWAR.
 * In Halo 3, with the IWHBYD Skull on, Marines may say when they throw a frag grenade on Legendary on Floodgate "this one's for Byrne!".
 * Byrne's fitting death date on November 17, alongside the Marines stating his name on Floodgate and the scripted Marine dialogue in case they live, led to the speculation Byrne was the sergeant who died and was infected by the Flood on the start of the level.
