Do You Think the Russians Are Starting to Get Under Some Serious Pressures?

There were a few occasions where tankers came in, but that was also partly because they were bringing in transport material as well. And did you see them using tankers in Syria or were those short missions that they didn't need to? No, generally not. The war is now in its ninth month, and there's been obviously a very high intensity air war going on. What do you think has been the impact on the airframes of the Russian fixed-wing aircraft, as well as the whole supporting infrastructure on the ground? Do you think that they're starting to get under some serious pressures in terms of things breaking replacement parts and so forth?
