How do I get power armour training I found the brotherhood but I dont know how to get it.
I done the quest still in the dark and another 1 where you have to help Hardin take over the elder can I still get power armour training?

I'm not sure with Hardin as elder, but when I had the default guy, he had me do an extra mission after Still in the Dark, and then gave me a full set of t45d armor and training.

Arcade Gannon has a quest that will give you power armor training, even if the Brotherhood one gets glitched out.

I sided with Hardin and cannot trigger him to take over, if I kill him, his question fails. How do I trigger his quest to start? I waitned over 5 days and still cannot get him to take power.
