This should have allowed access to dox that would have given a clearer picture of soviet military theory & intentions. So, it seems to me that there should now be a much clearer view of how the soviets really intended to prosecute such a conflict, as well as how they actually trained for it. There should also have been official  accts & analysis of the performance of their armed forces in the Afghan conflict. (as an aside, the stuff I've read has been all over the place in regard to this)
