Here's a really great Russian / Finnish film about the Soviet war in Afghanistan. The movie came out in 2005. It follows a group of young recruits from a their time back home, during their intense training, and culminates with an intense mountain top battle in Afghanistan against the mujahideen.
The film is mainly based on events which took place in early 1988 during the last large-scale Soviet military operation "Magistral". This film was given the Golden Eagle Award for the Best Feature Film by the Russian Academy of Cinema Arts. It's interesting to see the similarities in the combat that took place then, and what the Allied troops (mostly US) are facing now. The reason for our involvement is completely different though. Regardless of your politics, the action in this movie is fantastic. It's also really cool to see all the AK-74's, which are starting to make their way to our (US) civilian market in large numbers (semi auto versions that is). I have linked clips of the major battle scenes. Enjoy!
