The Supporters Groups… and there are a few of them wrapping themselves around Atlanta United as a part of the #17’s you see on kits all over the place in the Southeast…
The four officially recognized groups that you will see in the north end zone at Bobby Dodd Stadium every home match are Terminus Legion, Resurgence, The Faction, and Footie Mob.
Each has their own personality and approach to the game and the game day experience. But the questions about starting something organic and having it instantly be a part of the fabric of the franchise is worth exploring, as other expansion franchises (and those in place as well) might see how these four act as one come home matches.
