How did 183 days of conflict change the Ukrainian and Russian armies?

How did Russia prepare to attack Ukraine and what did it number on by striking comparatively tiny forces? What destiny was cooked to Ukraine? What mistakes did the Ukrainians make and what did both sides learn during the ongoing and evolving conflict for six months? Finally: what phases can we separate in this war and, above all, what next? Maciej Szopa talks about this with Dr. Marek Kozubel, who conducts his own regular reports on the war.
