I still don't get the militaristic part, even if we focus on the Viking era.

But you should not only look at the words when it comes to Civ Ability whats the effect?
Exactly! Militaristic gives a bonus to building barracks and gaining military experience, implying that a militaristic society has a willingness to support a large standing army and organizing it well.
The vikings weren't exactly notorious for either of these things. No standing army to speak of and not very organized at all.

Every free man had to carry a weapon with him. if you had a problem with another man you could challange him to a duel (holmgang) to settle it. You even had some warriors calling themselfs Berserkers who were alllowed to take everything a man had if he din't dare to face the Berserker in combat
I'm not a historian or anthropologist by any means, so I may be wrong, but these things are quite common in early societies, aren't they? No distinction between soldier and civilian (I don't think the Greek made this distinction, for example), trial by combat (the holmgång) and chewing on mushrooms to be a bit less afraid and more violent when you go into combat.
Well, perhaps the mushroom part, but you get my drift...
Violent? Yes. Militaristic? No
I'd go with commercial and expansionist, if I was you. But, apparently, I'm not. So I'll just advice you instead.
Looking forward to your finished civilization in any case. Good luck!
