Unranked servers do not count, they're just for running and gunning. You can use the weapons you've unlocked, you just won't be able to unlock more that way. But the unranked server software is a free download. I had one running once before the WOW craze took off; I could probably put it back up fairly easily. Just not sure if it would have Special Forces in it, either.
