Brotherhood T-51b Power Armor

The Brotherhood T-51b power armor 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, T-45d power armor, and with salvaged power armor. Power Armor Training is required in order to wear this armor.

This armor acts as a Brotherhood of Steel disguise, which will provoke hostility with NCR personnel until having peacefully completed the Brotherhood section of For the Republic, Part 2.

Locations

 * Hidden Valley bunker - can be pickpocketed from Head Paladin Hardin if he becomes Elder as he will not wear it.
 * Black Mountain - two can be found in a radioactive crater southwest, on paladins Hughes and Fairbanks. If having only found Fairbanks (paladin with the logs), Hughes' body probably glitched into the side of the crater. About 5 centaurs, and Moe are holed up in and around the crater.
 * Nellis Air Force Base - two can be found just outside the base. They can be found while avoiding the artillery shells flying in one's direction, or gain entrance to Nellis then come back and search in relative safety.
 * REPCONN headquarters - two can be found on the third floor. There are two downed Brotherhood of Steel members, one under a fallen chunk of the ceiling, the other against the wall, a few feet from Piers Isley's briefcase.
 * Four more can be looted from dead Paladins depending on how Veronica's quest, I Could Make You Care, is finished.
 * Can be obtained from Hidden Valley if the Courier has the Mister Sandman perk and kills sleeping paladins. (Doesn't turn any BoS characters hostile), however, in a "Hidden" position, with a silenced weapon, the Brotherhood will turn hostile unlike any other faction even if members are stealthily killed.
 * Can also be pickpocketed from sleeping paladins as they will remove it while sleeping. The paladin at the shooting range, however, will not remove his to go to sleep. Also, the paladins who sleep in the beds near the range are the only ones who remove their armor for sleeping. It's almost impossible to pickpocket it, even with a Sneak skill of 100 or a Stealth Boy.

Bugs

 * Brotherhood T-51b power armor is much more common than intended, due to the armor occupying a list meant to hold Brotherhood T-45d power armor. Among other issues, this results in the dead paladins found in the quest Still in the Dark being attired in T-51b armor, rather than the intended T-45d armor.
 * If you give the armor to a companion to wear, and the response is "This follower will not wear this faction's armor," the armor might disappear. The only way to resolve this is to reload a save.
