Inside the mess hall is the Boomer munitions manager's store at the north-west end of the hall way, there are various explosive weapons such as mines and missile launcher inside the store. Near the west entrance is an entrance to a kitchen with some Boomer chefs inside. In the middle of the hall are tables and chairs, as well as several Boomers eating. A couple of VR pods, similar to the Tranquility Loungers from Fallout 3, can be found at the southern part of the mess hall.
Inside the Boomer munitions manager's store at the north west end of the hallway a mini nuke can be found. It is in a box on the top, right hand shelf at the back, and must be stolen.
Near the western end of the building, there are many ammunition crates that primarily house missiles. All together, there are over 100 missiles scattered throughout various crates, all of which must be stolen.
As of patch 188.8.131.525, fewer missiles appear in the crates. It is still possible to find 15-20 missiles and various other ammunition, however.
