[@Jotunn Draugr] Not that I'm aware of. My mechanic is probably the closest, but he's just sorta generic boisterous muscle head. Take your pick. 

EDIT: That was the other thing I forgot to mention. Everyone was supposed to be Private or Private First class as ranks. Doesn't really matter too much, I guess, since Lance Corporal puts you in line to be second in command (a position we're currently missing), but no one's allowed to go higher than that rank. Zark's gonna be in charge for a while.
