I just got a bunch of 15mm Minifig Sweden troops as an extra in a trade...sounded good at the time, but I'm stuck as to what to use them with.
Well, you can always send them to me :-)
Did I mention I have Russians?
But since I'm pretty sure you will not do that, you can always paint them up and use them on the gaming table for yourself. After you do a little research, you will quickly discover that you can use them in battles against not only the Russians, but also the French and Norwegians.
The miniatures that Minifigs produce are of the later uniform, but why not use them for early battles as well. I gather most gamers will not notice the differences anyway.
