Okay..Deseret would have claims on some land, if you mind modeling that in. Not much, but nevada was part of the Utah Territory with a mormon minority population, same northern arizona. They had claims on arizona, a swathe of (southern cali, mostly) california and new mexico, also.
They're leader at this time, was of course, brigham young.
They were a theocracy.In this game, facist, maybe?
They had fanatical morale and dedication. Weapons not so good.
Used scorched earth against the US army..werent afraid to lose anything, and alot of them had come across the ocean and then across a continent to start a new life in the wasteland. Devoted lot, and tightly unified around the church, which is led by the prophet, also the president of deseret, and the quorum of 12 apostles, although I dont know how that would factor in.
The LDS private militia-army was called the Nauvoo Legion. the mormons organized the mormon brigade for purposes of fighting in the mexican-american war; it never saw combat.
The official flag of deseret is/was this one

I think it's very pretty.
LDS church doctrine states that christ will eventually come in missourri, so that may or may not have relevence.
The LDS was unlikely to get rid of such notions as blood atonement (human sacrifice, or a better word maybe execution, for severe crimes) or polygamy without federal intervention.
anything else..?
