Ukraine's Counteroffensive Takes Shape Amid Cross-Border Attacks.
Ukrainian troops have reportedly launched a counteroffensive against Russian lines, with some initial gains suggested by Russian ultra-nationalist military bloggers. The attacks are likely probing in nature, searching for local Russian weaknesses, and could be a pathway to cutting the Crimean land bridge close to Mariupol. The manoeuvre warfare is reminiscent of the second world war, and Ukraine will need significant battlefield superiority to be confident of success. The anxiety in Kyiv runs deep, with many expecting high casualties.
