Vault 101 security
More kids looking to get us all killed. Now it's up to security to keep them in line.”— Officer Gomez during Trouble on the Homefront.
The Vault 101 security is a department in Vault 101. This department enforces the Overseer's word as law in the Vault. Officers in are hand-picked by the Overseer himself for their discretion and loyalty. They are the only residents with authorization for carrying firearms, besides the Overseer. Vault security have a office located in the upper level.
The standard accouterments of a security officer is armor worn over a utility jumpsuit, helmet, and boots. As with all vault residents, officers have Pip-Boy 3000s. A few officers don't wear helmets. The officers can carry either N99 10mm pistols or police batons.
The Overseer commands the security force with the chief of security acting as his representative in his absence. Most of the officers obey the Overseer without question and have no qualms in injuring or killing residents during a crisis.
They are on par with a mid-level raider in terms of durability.
Getting through the quest "Escape!" without killing security guards, they can be interacted with most of them upon returning to Vault 101.
The Vault 101 security appears only in Fallout 3.
