WWI style war indeed. Trench warfare and excessive use of artillery. There are even attempts at chemical weapons use through detonation of ammonia storage by Ukrainian troops on retreat. The West likes this development, I think. Remember how Germany was appearing as a winner in WWI if you consider their significant land grab, until suddenly it wasn't, due to internal economic collapse. So the West predicts the same fate to Russia. Russians, on the other hand, think they can rely on internal resources much more than West does so they hope to outlast this conflict in such way. By spring time we'll see which side is in a better shape.
