"Hydraulics" effective in defending Kupinsk

Following the situation on the Ukrainian front, quite a few attention is focused on Pokrowsk in the Donetsk Oblast. And rightly, due to the fact that it is simply a very crucial city from a propaganda point of view, which the Russians have been trying to get for respective months. And fortunately, they don't succeed. However, equally crucial from a tactical and visual point of view is Kupansk, the second largest railway node in the Kharkiv region. This town and another towns in the Kharkiv region have been practically since the beginning of the full-scale war under Russian business for over half a year. However, in September 2022 the Ukrainian military broke out of the Cup and now defends it with all available means.
