Trivia

 * The achievement's name is a direct quote of Avery Johnson's last words.
 * It also could be referring to the fact that this is the final mission of Bungie's last Halo game, meaning to end their involvement in the Halo franchise with a "bang", in this case the last action the player performs is shooting down a Covenant cruiser.
