The New England Alliance is a faction in Shattered Union. It is 1st out of 7 in the order of movement for each turn in the campaign. In addition to the in-game description of its partial or complete member states, West Virginia appears to have sided with the NEA, since Morganton, Parkersburg, and the state capital of Charleston can all be found in the Ohio Valley territory. The New England Alliance's time of formation is not specified, but it would definitely be following the secession of California and Texas. The NEA is one of three factions to share a border with Canada at the start of the game, and the only one possessing a territory in which Canada can actually be seen- the Ohio Valley territory.
The New England Alliance, ironically, names its unique heavy tank the FCS Bragg, after Confederate general Braxton Bragg. The FCS Bragg is one of three factional heavy tanks to lack an actual main gun- the others are the anti-infantry FCS Jackson of the California Commonwealth and the Great Plains Federation's FCS Grant, which fires a heavy mortar. The FCS Bragg mounts several guided missile launchers in its turret, substituting them for the more typical main gun found in heavy armor.
In-game description: "The New England Alliance is made up of parts from the former states of New York, New Jersey, Pennsylvania, Ohio, Maine, Vermont, Connecticut, Rhode Island, Massachusetts and New Hampshire. Members of the New England Alliance are driven and feel a strong sense of purpose in this war. Though only comprised of three territories, the NEA has one of the highest population densities in America. Before the secession, New Englanders felt that they were not given a representative voice."
The New England Alliance starts with a number of ex-US military units that have fallen into its hands, and it is able to manufacture the full array of American military units to put on the field. NEA units appear colored teal on-map, and include:
FCS Bragg, Abrams, M60, JSF, Super Hornet, Stealth Bomber, A-10 Thunderbolt, Crusader, MERL, Paladin, Big Tom, Humvee, Striker, Bradley, LAV, Sheridan, M8, Defense Tower, Avenger, Vulcan, Warrior, Super Cobra, Apache, Militia, Engineers, Commandos, Bunker, Partisan NE, and 155mm M777.
