|Go to Mariposa Military Base.|

|Reward: 1500 XP, a weapon of choice|
Before receiving this quest, the player must have explored the Hub and talked with the locals about the missing caravans, however finishing any of the quests is not required. The player must also have spoken with Cabbot after being initiated. Then they can finally speak to Maxson and receive the quest.
Initial reports from scouts, as well as the location of the mutant body that Vree recovered, indicates that there's a massive source of super mutants brewing in the northern wasteland. The Elders of the Brotherhood of Steel want the Vault Dweller to verify the rumors.
To complete the quest, the Vault Dweller needs to head northwest of the bunker on the world map. After a few days of travel, the military base will show up. Entering the location is considered scouting.
When the existence of the base is revealed to High Elder Maxson, he convenes with the remaining Elders and the Vault Dweller may attempt to convince the Elders that he requires Brotherhood assistance in storming the base or Cathedral.
Once Maxson gives the quest, the Vault Dweller needs to ask for an additional weapon. He will then redirect them to Mathia, who will allow the Vault Dweller one of the following:
- A DKS-501 sniper rifle
- A Rockwell BigBazooka
- A Ripper vibroblade
- A Big Frigger power fist
- A Wattz 1000 laser pistol
- 1500 XP
