2 Lima 4 was a UNSC Army trooper who was a part of the unit 2 Lima, that fought during the Fall of Reach. During the Battle of Viery, he was pinned down by fire from a Tyrant, contacting Carter-A259 of his unit's status. The Tyrant was then destroyed by SPARTAN-B312 and Catherine-B320. He then requested an airstrike on 3 Scarabs attacking his position, which was approved by Air Control after Carter-A259 confirmed that the Tyrant was destroyed.
