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 Rivet City security uniform (an inferior variant of combat armor but excellent to repair Reilly's armor with) and a Rivet City security helmet (a combat helmet with a Plexiglas face shield in front). They wield 10mm SMGs. In terms of durability, they're about on par with mid-level raiders, and go down after 2 or 3 hunting rifle shots.

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 decent source of repair parts for combat armor and the 10mm SMG, although killing them for their equipment will of course put you at odds with Rivet City. As well as causing the player to lose karma.

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.

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.

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 an NPC, supports this spawn point for Rivet City guards for unspecified reasons.
