Bald and gribbly.
Hot damn, dude. I'm glad they're on my side.
I've been considering getting a few squads of Space Wolves to 50/50 on some smaller games just for looks but damn, if that's how they roll... I might need some to beef up my assaulting.
They're not all out assaulty as say the Blood Angels, I would get hold of the codex and have a look. What they do have are the sagas, which are very very snacky.

This kind of gives a pretty fair view of what to expect.
