The line comes from Sergeant Major Avery Johnson in Halo 2, Bungie's 2004 first-person shooter and the second entry in the Halo series. Johnson, a fan-favourite UNSC Marine leader, delivers the order during the game's campaign, and the clip has since become a staple for Halo fans sharing gameplay, memes and squad montages online. Its direct, no-nonsense tone fits team-based shooters perfectly, which keeps it in regular use long after Halo 2's release, especially in videos celebrating teamwork, strategy and coordinated attacks.
