A four-man sniper unit. Does exactly what you think they do - kill things dead from a distance. These fellows will either shine or do nothing spectacular, seeing as your opponent don't want you to take out impoartant support pieces before they can do their thing. Then again, that draws attention away from your other stuff...

Been with me since day 1, and they've had a lot of game time since then. I rarely go without these guys in a list.
