- A copy of Duck and Cover! - On the middle bookshelf with the grenade rifle and ammunition.
- Col. Blackwell's key - In the right-hand filing cabinet against the southwest wall. The key can be used to unlock the weapons chest in the Vault 34 armory containing the pulse gun. Without the key, a Lockpick skill of 100 is required to obtain the unique weapon.
- The inventory transfer order - A note related to the pulse gun, inside the right-hand filing cabinet.
- A unique version of the head wrap - In the left bathroom locker of Pearl's barracks. Although the Pip-Boy identifies it as a regular head wrap, it differs from the regular version for having a faded green and red pattern on an ochre background.
- All items in the building are flagged as owned. Taking anything will result in a loss of Karma and possible Boomer infamy.
- Despite the building's name, Pearl sleeps in the women's barracks.
Pearl's barracks appear only in Fallout: New Vegas.
