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.

First Expeditionary Force, this is L-H with a recorded Priority Gamma message.
Papa Romeo missed the last four check-ins. No contact since crossing the Rockies. Scribes estimate unit position in the vicinity of Lincoln. Orders are to re-establish comms with L-H ASAP and provide a full report of whereabouts and activities since last communication.
Acknowledge on coded channel two three.
- ↑ Lost Hills message 5: "First Expeditionary Force, this is L-H. Elder Maxson recording.
Paladin Rahmani, your unit has now been out of contact with Brotherhood headquarters for over three months. Our Scribes estimate that your unit should be entering Appalachia and closing in on the ATLAS Observatory shortly. It is imperative that your first order of business after securing the facility is to reestablish communications and provide a full report on your activities during the period of radio silence.
You now represent the Brotherhood in Appalachia. When you restore contact with us, there will once again be one Brotherhood on both sides of this land and your deeds will enter the Scrolls forever.
Adhere to the Codex. Conduct yourselves with honor.
Maxson out. Message repeats."
