Are those Vikings? They look more like Huns to me.
According to a site that watches those kinds of things (This one here) calls them barbarians. Most of the other sites I found dealing with that campaign calls them barbarians. Of course, that term would cover the Vikings, the Huns, the Visi- and Ostragoths, and a host of other cultures of the day.
Seeing as I have no knowledge of the other's pantheons, I can only comment on the Norse, and therefore I'll assume that the ad is using Vikings in their ads.
