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 Citadelby Paladin Gunny, access to which is granted at the beginning of the main quest Picking up the Trail, or by finishing the Anchorage quest in the Operation: Anchorage DLC pack.

Obtaining the perk
After gaining permission from Elder Lyons, Paladin Gunny in the Citadel Courtyard can teach you how to use power armor (which literally just consists of him telling you to relax your muscles while wearing Power Armor). Brotherhood members will say that Gunny is in the bailey, but that is another term for the courtyard. Once you have undergone the training, you may use any kind of Power Armor, including the Enclave's and the Outcasts' varieties.

If you do not ask for training on your own, you will get it automatically at the end of The American Dream when you become an honorary member of Lyons' Pride.

You automatically gain this perk when you finish the Anchorage Reclamation simulation in the Operation: Anchorage DLC.

Console command
Through normal gameplay, training is required to wear power armor of any variety. However, the skill can be unlocked via the console in the PC version by typing "setpccanusepowerarmor 1". This does not add the perk to the list of the player's aquired perks, but it does open the use of power armor. It may be advisable to turn off the flag before actually training for the perk by using "setpccanusepowerarmor 0".
 * The method used to hack the actual perk can be found on the "Console" page.
