I haven't seen Enemy at the Gates, but I've heard about it. And to be frank, all I had in mind was a foot soldier facing off with a sniper, or rather trying to survive. That is not to say that the sniper is going to be super-efficient and can pin a fly to a wall from miles away. They will have their faults as much as the soldier. I'll admit, it does sound iffy to me too, and I should probably put more thought behind it than I did beforehand.
