Rivet City Security Force

Led by Chief Harkness, Rivet City security serves as the security and police force of Rivet City.

Duties
The members of Rivet City security guard key points within the city, such as the bridge into the city and the market, as well as patrolling the ship's corridors for "troublemakers."

They seem to have a rather laid-back attitude towards their job, informing the player that if "someone steals something from you, take it back. If someone shoots at you, shoot back." and stating that they will only intervene against crimes they personally witness. They do, however, become hostile towards and hunt down anyone seen committing acts of violence against Rivet City inhabitants (namely, the player character).

Unnamed members
Rivet City guards wear a security uniform. They wield 10mm SMGs. In terms of durability, they're about on par with mid-level raiders.

Rivet City security guards carry a "hangar key" to the Marketplace.

There are an unlimited number of Rivet City security, as new members will gradually respawn to replace any that you kill. This makes them a source of repair parts for combat armor and 10mm SMGs. However, killing them will cause Rivet City to turn on you and cause karma loss unless the guards are killed in their sleep with the Mister Sandman perk.

Combat
The 10mm SMG is the standard-issue firearm for all Rivet City security officers. They have excellent training with small guns, though, so they'll often appropriate a better weapon from Flak 'N Shrapnel's or a dead foe. Officers sent on caravan duty are also issued grenades.

Broken Steel
In Broken Steel, Rivet City Security can be seen acting as guards for the Water Caravans transporting aqua pura from Project Purity to the rest of the Capital Wasteland. Each water caravan is usually accompanied by 2 Rivet City security guards armed with 10mm SMGs. If spoken to, these guards often express concern over water caravan duty, stating that it is a suicide mission. Indeed, these caravans often fall victim to attacks by super mutants, Enclave, critters, and the Wasteland's various other hostile inhabitants. The security guards will also have a water crate key in their inventory along with the hangar key.

Water caravans also sometimes have Brotherhood of Steel Initiates or Knights instead of Rivet City security as guards. These heavier-armed caravans tend to perform better when ambushed by hostiles.

Mothership Zeta
In Mothership Zeta, an abducted Rivet City security guard can be found in a holding cell. If the player completes Mothership Zeta and goes back to the cell, the guard will be calmly pacing round the room. However, if talked to she will respond with "This can't be happening, this can't be real!" as though it were the player had just esacaped his/her cell.

Quotes

 * "I oughta throw you off this ship for what you did, but the boss says Rivet City has to forgive and forget. Still, I'm watching you." (If the player has committed a certain crime on the ship.)
 * "They're all eating breakfast at Gary's, they'll still sell to you though." In the morning, when the Rivet City market people are at breakfast.
 * "They're all eating dinner at Gary's, they'll still sell to you though." In the evening, when the Rivet City market people are eating dinner.
 * "Welcome to Rivet City." The guard will say this when you use the intercom.

Bugs

 * Occasionally Rivet City guards can be found elsewhere in the wasteland wandering aimlessly around. The Super Duper Mart, a common spawn point for many a NPC, supports this spawn point for Rivet City guards for unspecified reasons.
 * When you are fully hidden, and kill a Rivet City Officer when no one is around, other Security Officers will become hostile to you, until you return 24 hours later.
 * Sometimes when you save at the top of the Washington Monument, then fast travel to Rivet City, kill the guard at the entrance, reload your save and fast travel to Rivet City again, the guard will be hostile as if you attacked them. Killing the guard again and then reloading the save should take care of this problem.
