Changing a face to a Campaign character

[Blackfox34]

Want to know how to use the faces from the SP of ARMA 2 and OA and possibly PMC and BAF as they are modeled great.

I particularly want this one, but can't find the identity or face name.

Any help would be great


Edit:

I know how to use the setFace and everything and how to manually change faces with the config, just need the actual classnames.

You can't use the faces of any Razor Team member, or any of the OA main characters, because they are on custom head models. You can use the BAF and PMC faces though.

His unit is Piece his unarmed unit is Pierce_Light his face is PierceHead_EP1. I'm not really able to get it working though.
