Power Armor Training (Fallout 3)

Power Armor Training is a Fallout 3 perk. It is necessary in order to operate or wear a suit of Power Armor and a Power Helmet. It can only be gained at the Brotherhood of Steel Citadel, access to which is granted at the beginning of the main quest Picking up the Trail.

After gaining permission from Elder Lyons, Paladin Gunny in the Citadel Courtyard can teach you how to use power armor. Brotherhood members will say that Gunny is in the "Baily", but that is another term for the courtyard. Alternately, you will get this perk at the end of The American Dream when you become an honorary member of Lyon's Pride.
