The Brotherhood-specific variant is not as rusted as the regular variant, due to the Brotherhood's high maintenance of weapons and armor. The armor is relatively rare in the Mojave Wasteland, as the Brotherhood of Steel, the only faction which regularly uses power armor has its own faction-specific version of the armor. In order to wear the armor, one must first acquire Power Armor Training, which can be obtained by completing the quest Still in the Dark and then completing Eyesight to the Blind or Tend to Your Business, or by completing the For Auld Lang Syne quest.
The Mojave variant of the T-51b is a type of powered infantry armor.
A pre- War product of West Tek in conjunction with the United States government, T-51 power armor is made of a poly-laminate composite, shielding the user from radiation and damage while providing increased strength.
