Assessing Ukraine's Strategies in the Russo-Ukrainian War.

Satellite images analyzed by BBC Verify reveal extensive defences built by Russia in southern Ukraine, including trenches, bunkers, anti-tank ditches, and dragon's teeth. The build-up of defences is in preparation for a major Ukrainian counter-attack, which is expected to be a crucial test for Ukraine as it seeks to prove it can achieve significant battlefield gains with the weapons it has received from the West. The defences are likely to be a precaution, rather than a sign that Russia expects to defend a seaborne assault, since Ukraine has little naval capacity.
