Sex in battlefield conditions hardly seems worse than sex with a pie.

I thought the love story was the best part, because of the political overtones. A lot of people missed it, but right at the end the propaganda officer realizes that the love triangle has driven him to do bad things to the hero. I forget the details. Just before he sacrifices himself, he realizes that if two men can't share one woman, then there's no chance for millions of Russians to share everything under communism. Human nature conquers all.
