I'll list my own opinions about the traits too. I'm overviewing Finland culturally, so in this I've taken account the whole history, not just the time of independence.
What comes to the matter of Finland being Militaristic, it has two sides. First side is that we were under Swedish rule for a long time, and were involved in many wars with them. The effect of this was (naturally!) that Swedish crown drafted Finnish farmers, mainly in the cavalry service - the Finnish Hakkapelitas were known as one of the bravest part of the cavalry. However, they used the Finns so much that they literally ran out! So compared to population of Svealand, they used relatively much, much more Finnish troops in service. So this description supports the Militaristic trait.
And the other side? Well, the Finnish were not interested in war (of course, if you go to the 17th century and ask German farmer his opinion about the war, he will slash you in the head with his pitchfork!), at least not in offensive way. Finland was (and still is) sparsely populated, and so there was enough room and food for everyone.
But then, again, they resisted the crusades made by the English, and the landing of the Swedes. The Finns weren't organized as well as their conquerors, and lacked the government of any form - in fact they were just like any other native community, who are willing to defend what is rightfully theirs.
So my conclusion is that I'll bend slightly towards Militaristic trait, after I've taken account the Swedish rule and how they used us, the bloody civil war which ended the Russian rule and the World War II, where we were fighting, for the first time in our independent history, offensively. And today, as has been noted, we have very good knownledge of military technology suited for protecting our country.
OK, more ideas of traits. Agricultural? No. While it may seem the only one that fits, it cannot be. Almost all of the European countries have better food production potential and -capacity than Finland has. And the more we look back to the history, the more wildlands we will see - there was just that much of farming and hunting that the people stayed alive, and often not even that much (how else can we explain the fact that we have so little population compared to those who really have the farming capacity?)
Seafaring? No. While the present-day Finland has much of ship building industry (and a few fine cruise ships, too

), it has nothing to do with the Seafaring trait.
Industrial? Could be. I'm not going to say a single word about Nokia, as that matter has been already been discussed. I'm concentrating again to the big picture. Industrial means productivity. And we Finns have always been very productive. Because we have had to. Perhaps the most important export product were the naval supplies, mainly tar. Finland had many big customers, including England, Netherlands, France and even Spain. Unfortunately, under the Swedish rule and in the age of mercantilism and after, the Finns did not benefit from it, but it still shows that a little country can achieve great efforts.
So I'd suggest the second trait would be Industrious. However, it may also be Commercial if you want to take a different point of view. I'm so tired, it's 1 AM and I'm still here! So I think I'll leave this for now. Any counterthoughts? Hope this gives you some new vision to the topic!
Lastly, I must recommend you all to read Peter Englund's books, of which the first concentrates on 30 years was, the second in the time of warrior king Gustaf II Adolf, and the third in the battle of Poltava (there are more books, yet I haven't found them). They are filled with interesting facts about the time and habits, science, politics and war. Mostly war.
