The Brotherhood scouts are three scouts for the Brotherhood of Steel in the Mojave Wasteland in 2281. They can be found spread throughout the Mojave Wasteland, posted on three vantage spots near other faction's settlements, following their movements.
These three Knights were sent out by McNamara on scouting missions. When the patrols failed to return, McNamara assumed the worst and sent a single communication to the scouts to hold position and maintain radio silence. They hold reports from nearby NCR movements which the Courier needs to acquire and return to McNamara.
Still in the Dark - McNamara wants the Courier to contact the scouts and gather their reports. Once found, they need a secret phrase to be responsive. The Courier should return when all reports are gathered.
