Security uniform

The security uniform and matching security helmet are pieces of armor in Fallout 3. It comes in two versions with different appearances but identical stats.

Characteristics
The Rivet City security uniform and the matching Rivet City security helmet are the standard protection for members of Rivet City security. Whereas the Tenpenny security uniform is worn by the guards of Tenpenny Tower, the Tenpenny security helmet can be found in the game files but is not actually used in the game.

The two security uniforms have the lowest damage resistance out of all combat armor variants, offering slightly less protection than even the Talon combat armor. Nonetheless, they provide better protection than most clothing worn in the wasteland, including merc outfits and raider armors, and convey a small bonus (+5) to small guns.

Rivet City security uniform
The black-colored Rivet City security uniform and helmet are worn by the Rivet City security guards at Rivet City. Visually, the uniform appears to be scratched and worn. It also seems to have a very faint camouflage pattern if looked at closely enough (more visible on the female version of the armor). The helmet comprises a black combat helmet and a Plexiglas face shield identical in appearance to the Vault 101 security helmet (See Vault 101 security armor) with 2 main differences, it has a higher damage resistance and can be equipped with eyewear like sunglasses but won't be visible when worn by a character with the exception of biker goggles and the ghoul mask.

Tenpenny security uniform
The khaki-colored Tenpenny security uniform is given to all of the security guards at Tenpenny Tower.

Locations

 * Rivet City security guards wear them. The uniforms can be obtained by planting items (better armor in this case) or looting the guards after they are killed.
 * Dusty of Big Town, who wears one of the helmets, is the only character to wear a part of a Rivet City uniform without living in Rivet City.

Bugs

 * When male characters equip the Rivet City security helmet, some of the player facial texture, mainly the eyebrows will change much like when you add facial hair for the first time to a clean cut player . This will change back when you remove the helmet.
 * When worn by a female character, the Tenpenny security uniform has the green sleeves from standard combat armor. Bethesda used the standard combat armor mesh with an alternate texture, however the 3D index for Arms02 was mistakenly set to 4 instead of 2 causing the texture error.
 * The above bug isn't an issue for the Fallout:3 GOTY addition. A female character wears the Tenpenny security armor without the texture clash. The color is exactly as seen in game.
