Again, please focus on the present when creating and guiding your characters. Zombie, you're free to start with the power armour so long as it's a T-45d model. It makes more sense to be suited in the same gear that was used in Anchorage than it does a model only released a year prior and probably dedicated to combat. Read up on some of the limits of the 45, such as mobility, areas of exposed circuitry, and energy consumption. Otherwise, you're good to go! 

Expect an IC post tonight.
