Two years after Russia’s full-scale invasion captured nearly a quarter of the country, the stakes could not be higher for Kyiv. After a string of victories in the first year of the war, fortunes have turned for the Ukrainian military, which is dug in, outgunned and outnumbered against a more powerful opponent.
