|I saw this the other day, and was surprised at how good it was. I had only heard it in passing as a low budget Afghanistan film, but on watching it, the budget was obviously huge - with the amount of authentic kit shown.
Some of the special effects were a bit dated (blue screen explosion stuff I guess), and some of the acting of the battle was a bit dubious with the whole Afghan human wave thing (for all I know that's how it played out) - but all in all I would well recommend it. It had some nice touches to detail you don't often see in films - for instance one Soviet soldier burning his hands on the barrel of a PK.
It's basically the parallel of "FMJ" or "Platoon", only in the context of the Soviets in Afghanistan.
