Unless the Russians have greatly improved the quality control that bedevilled much of the Eastbloc's military output, I can't even see giving the stuff a second look. (See story below). As well as being a somewhat unstable place politically, IMHO Russia can be a very tricky and frustrating place to try to do business. It seems to me that there is far more corruption and outright criminal activity than we face here in the West (not say it doesn't exist...). How would we sort out business or trade disputes with a Russian manufacturer? Who would we appeal to? The Russian court system?
Story: In 1993 I served in Mozambique with a number of Czech Army officers. One of them, a Gunner, had commanded the first battery of the wheeled 152mm SPG "Dana" that you may recall from your AFV recognition training. When it appeared, we regarded this as a pretty impressive piece of gear. What the LCol told me was quite different. He said that when they received the guns and took them out for field training and firing, serious problems began to appear. The brake lines were mounted on the outside of the hull, so that when travelling cross country they were often damaged, with the result that it became difficult to stop the gun when moving at any speed. The autoloader that brought ammo from a storage magazine to the gun frequently jammed, requiring the crew to leave the NBC-protected gun cabin and manually free the jammed ammo. Overall, he said, it was a POS and a big disappointment.
Now: have Western armies bought gear that has also turned out be a disappointing POS? Yes, of course. The difference, I think, is that those quality problems in the West were not symptomatic of the whole industrial system. As well, we in the West have a thing called "competition" that tends to push defective firms towards the rear, or gradually out of business, if it is allowed to function properly.
