There are a couple different ways to obtain training for Power Armor:
- You can ask for training from Paladin Gunny at the beginning of the quest Picking Up the Trail
- You will automatically receive this perk at the end of the quest The American Dream right before the start of Take it Back!
- Or if you have the Operation Anchorage DLC you will receive it at the end of the simulation.
- Or you can do a glitch which allows you the power armor training anytime you want it, including the very beginning of the game, and u can get the Smugglers End ;laser pistol while you're at it. Here's the Youtube video link: http://www.youtube.com/watch?v=YYHz3zeKFP8: if you're on xbox and was recently updated, this glitch still works. I hope I helped.
