The battalion was a distinguished unit with a valiant history, conducting hundreds of special operations and fleet-support actions during the Human-Covenant War, the Insurrection that had preceded it, and the conflict with the Remnant that followed on its heels. It was commissioned in 2521 and its current commander is Colonel Matthew "Maddog" McDonnell.
