The conflict in Ukraine is about to enter a new high-intensity phase as Kyiv’s troops gear up for an anticipated counteroffensive. Ukraine’s persistent lobbying of allies has yielded significant results as NATO members have gradually relented about supplying high-tech weapons. The fighting in the coming weeks is likely to be bloody, as Ukraine aims to take back territory which Russia captured in the opening weeks of the invasion. A mix of complex weapons from across the world will require the adept handling of logistics if the offensive is to keep up its momentum, and supply and repair are vital for any advance to be successful. The Ukrainian military will have its work cut out. Russian forces have had months to prepare for the series of battles that could define the nature of the war. Both sides realise what is at stake. Russia will not give up its ground easily, despite talk of low morale among its forces.
