The new Ogre faction is coming soon to tabletops in Vanguard. They're able to be hired by anyone, so they could be on your side of the table or your opponent's. Either way, it's good to know what you're fighting with or against, so Mantic has posted up some more previews for you to check out.
From the article:
After yesterday’s ogre preview, which looked at some of the major changes to the existing units (you can read that here), today we’re back with a preview of some of the new units that you can add to your warband.
