I ask this because "In the year 2254, some time after the (apparent) destruction of the Enclave, the Brotherhood's ruling council, based in the Lost Hills bunker in Southern California, decided to send a contingent of soldiers all the way to the East Coast, with two important objectives. First, to scour the ruins of Washington D.C., once the nation’s capital, to recover any and all advanced technology. Second, to investigate the reports of super mutant activity in the area."
I can see the BoS going "lets send some people out East to DC" after all New Vegas has an image of Mr.House standing in front of what can only be
But how did they know of the super mutants? Why would stupid mutants few in numbers in DC be a threat to them in California? Its possible they got their hands on Vault records but still its not a threat to them. Nothing on the scale of the Masters Super Mutant Armies. With over 2000 miles between Western BoS and DC I don't see it as possible for the BoS to know, at least nothing worth making it a second objective. MWBoS don't seem to be in contact with the Western BoS so they would not act as a relay and why would they not just take them out if they were talking to one another?
Edit: I say threat because, with the BoS in decline they would need more reason to send people all the way to DC then just find tech that might not even be there anymore. I also should have Called this Topic FO3/New Vegas Canon issues...
