- Courier: "What are howitzers doing at an Air Force Base?"
Pete: "You're right, they weren't here when we discovered Nellis! We found the guns at a huge weapon depot called Area 2, many miles from here! It took many weeks to drag the guns and their ammunition back to Nellis - and it was the last time any of us set foot beyond our homeland!"
- Fallout: New Vegas Official Game Guide Collector's Edition p. 43: "Boomers":
"Fifty years ago, a group of Vault 34's dissidents struck out on their own and started using Nellis as a base. Over a long period of time, they eventually decided to call Nellis their home. They learned a great deal of information from the records at Nellis and used that information to open the weapons storehouses at (currently unknown locations called) Area 2 and the Hawthorne Army Depot. The result of their efforts was an enormous stockpile of heavy ordnance, artillery, and small nuclear weapons."
