https://www.youtube.com/watch?v=SiF_MpHcjd0Pretty good documentary , but the focus changes as it goes.
It begins as an engineering admiration of the Mi-24 , one of the best gunship helicopters ever made.
About halfway through it is about USSR policy and Afghanistan , then it is about Russian conscripts and Mujahadeen , then it is about the conduct of the Afghanistan war, then again it is about Russian conscripts and Mujahadeen plus the stinger missile , then again it is about USSR policy and Afghanistan, finally they mention the Mi-24 again.
If WWIII had happened as a conventional war in Europe, our tanks and troops would have been opposed by thousands of these, very tough helicopters.
