Much of Ukraine's military was mobilised only after the Russian invasion in late February, drawing many of its soldiers from civilian life.
In recent weeks, Ukrainian troops have pushed towards the Russian border after Russia's offensive on Kharkiv, Ukraine's second largest city, stalled.
For weeks, Russia has been withdrawing forces from around Kharkiv, suggesting it may redirect troops to fighting in other areas of eastern Ukraine.
