This was found here, in another thread, I just saved it.
Actually they focus fine on the Soviet made bodies. The Soviet QC might have been lacking, but frankly they're pretty damned good engineers. They could get 90% of what the West did with two sticks and a rock. I was constantly amazed at how innovative they could be when I would see a knock off and realize just what they had to work with.
