The UNSC Army Special Operations Group (ASOG) was a special operations force of the UNSC Army and the UNSC Special Operations Command established in the Galactic Era. It was previously an audacious and controversial special access program operated under the umbrella of the UNSC Office of Naval Intelligence, but after the Beyond Veil's Azure Crisis, it was reformed into a more legitimate and accountable UNSC Army special forces unit in the dawn of the 27th century.
