25mm alien combat armor

I'm looking for a 25mm figure in combat suit or battle armor with a
helmet 
that looks like it can fit a snout (as in a dog's snout).....  Any
suggestions? 
Other than Space Marines?  I want to build a squad or three of Vargr
from 
Traveller to use in boarding scenarios once I get my 25mm deckplans done
(though 
we'll probably actually have gravitics by the time that happens).  
Thanks,
Jed Docherty
