Brotherhood T-51b Power Armor

The  is a piece of armor in Fallout: New Vegas.

Characteristics
Brotherhood T-51b power armor provides a damage threshold of 25 as well as a bonus of 1 to Strength and +25% Radiation resistance. It can be repaired with T-51b power armor. To be able to equip it as a usable item you must first complete Power Armor Training.

This armor acts as a Brotherhood of Steel disguise, which can make NCR hostile towards you, unless you have allied the NCR and the Brotherhood via For The Republic, Part 2 quest.

Locations
You can find it on dead Brotherhood of Steel members in the Still in the Dark quest:
 * Two can be found just outside the Nellis Air Force Base. You can find it while avoiding the artillery shells flying at you; or gain entrance to Nellis then come back and search in relative safety.
 * Two can be found on the third floor of the REPCONN Headquarters. You'll find two downed Brotherhood of Steel members, one under a  fallen chunk of ceiling, the other against the wall, a few feet from Piers Isley's Briefcase.
 * Two can be found in a radioactive crater east of "Hidden Valley" (If you only find the body of the dead paladin with the logs, the other body probably glitched into the wall). About 5 centaurs are in and around the crater including a bigger centaur called Moe.
 * Four more can be looted from dead Paladins depending on how you finish Veronica's quest, I Could Make You Care.

Bugs

 * Sitting on a bench or couch while wearing the armor will cause the shoulder guards to move out of place.
