Just like in the original game, the United Earth Federation (UEF) is the most recognisable faction with its blocky, pure military design. They're "big on artillery" in Supreme Commander 2 which is proven by a ranged minor land experimental, the Fatboy II, and a dedicated artillery experimental turret. The UEF can even shoot their own units out of an artillery cannon across the map right into the battle with the troops having been built inside the cannon itself. UEF commanders also have the advantage of being able to start producing powerful gunships earlier than the other factions.
