Brotherhood First Expeditionary Force

The Brotherhood First Expeditionary Force is an upcoming faction, made up of Brotherhood of Steel soldiers sent from Lost Hills to re-establish contact with the Appalachian Brotherhood.

Background
When Roger Maxson formed the Brotherhood of Steel following the Great War, he used surviving satellites to communicate with survivors across the country, and attempt to recruit them into the Brotherhood. He succeeded in contacting Elizabeth Taggerdy, who formed a Brotherhood chapter with her Ranger unit in Appalachia. Contact was lost with Taggerdy as these satellites failed, and the Western Brotherhood left unaware of the outcome of their war against scorchbeasts and the accompanying Scorched Plague.

Led by Paladin Leila Rahmani, the First Expeditionary Force was sent cross-country from the Lost Hills bunker to re-establish contact with the lost Appalachian chapter of the Brotherhood. After crossing the Rocky Mountains radio communications were lost between Lost Hills and the Expeditionary Force, which have yet to be re-established.

Appearances
The Brotherhood First Expeditionary Force appears in Fallout 76, mentioned in The Legendary Run, introduced in the One Wasteland For All update, and expanded upon in Fractured Steel.
