From Halopedia, the Halo wiki
For the UNSC naval officer, see Jenkins (captain). For the UNSC Marine assigned to the UNSC Pillar of Autumn, see Wallace A. Jenkins.
L. Jenkins was a UNSC Marine infantryman who participated in an engagement against the Covenant during the Human-Covenant War. He, L. P. B., and another Marine barely avoided a Type-1 Antipersonnel Grenade during that engagement.
His name is a reference to Leeroy Jenkins, a meme from the MMORPG World of Warcraft. In the clip, Leeroy ruins a carefully planned battle plan by charging straight into a room full of enemies while shouting his name, resulting in his entire raid party getting killed within seconds.
