Spartan Elijah Townsend was a UNSC Marine who fought in the latter half of the Human-Covenant War. After the war, he was offered a position in the SPARTAN-IV Program's second class, which he accepted. After completing training and augmentations, he was assigned to Fireteam Blitzkrieg, under the command of Oliver Braun, a veteran who fought throughout the entirety of the war. In late 2558, Blitzkrieg was reassigned to the Office of Naval Intelligence's Special Activities Division's Operational Detachment-Sigma to fight against the threat of the Created. Shortly after the formation of ODS, they were deployed to the former colony world of New Zaječar to prevent the Created from gaining control of the Forerunner munfactorae located there. During the raid, he was killed in action by Promethean forces.
