Asymmetrical Action Group
From Halopedia, the Halo wiki
Late in the Human-Covenant War, the Office of Naval Intelligence created the Asymmetrical Action Group as a cross-branch effort to disarm, disrupt, and dissolve Covenant activities. The group was formed around unconventional warfare veterans, though it eventually began to incorporate Spartans into its ranks.
Though the AAG's non-Spartan operators wore their own standard armor, the Beta-5 Division contracted Chalybs Defense Solutions to create a variant of the MJOLNIR Powered Assault Armor for its in-field Spartan operators. The resulting product, the MJOLNIR Mark V Operator variant, is designed to provide detailed on-the-fly transmissions that can circumvent most Covenant security networks.
