Brotherhood of Steel

Fallout Lore
The Brotherhood of Steel (or just BoS) is a Extremely Powerful and highly regarded Post-War faction that traces back its heritage from before the bombs fell. Originally the founding members were involved in 'The Mariposa Rebellion' as the guards of a scientific experiment and after realizing about the Forced Evolutionary Virus that the scientists were experimenting on they officially declared their dissertation from the U.S. Army and founded the Brotherhood of Steel in California under Captain (High Elder) Roger Maxson.

Since the events at Mariposa the Brotherhood has made it its goal to secure and contain technology no matter the circumstance and thus became one of the most technologically advanced Factions in the Post-War United States only rival to the Enclave and the Shi.

However as the Brotherhood set on 'Crusades' out East to recover new technologies the leaders of each group sent out altered the goal of the Brotherhood slightly and eventually creating their own 'chapters' of The Brotherhood. Some of them have totally different goals in mind such as helping civilians and recruiting outsiders.

FactionWars!
In FactionWars! The Brotherhood is an extremely powerful and easy faction to play as, they are a good ally for those not playing them and boast the largest Tech-Tree in-game. They have many Commanders and leaders and can defeat other factions easily. Their focus tree however is broken into three branches representing each of the main chapter's ideologies. Their un-unification is their biggest flaw and The West-Coast Brotherhood can even trigger a Brotherhood Civil War.
