Martha & UNIT???

So we know Martha is back.... but is UNIT back as well? And is Martha a part of it???

We know that Martha will be appearing in Torchwood, so is obviously a part of that, but these new pictures (found on freemaagyeman.com) Suggest that she is more a part of UNIT than with Jack's team.

This kinda fits in with some rumors that I've heard about the climatic series 4 finale where almost everyone is going to be involved - Donna, Martha, Rose, Jack, etc - which could also bring in Torchwood and UNIT. We shall have to see.
