Igor Rusakevych walks up to a desk and signs a few papers before a serviceman in army fatigues shakes his hand and welcomes him into the Ukrainian armed forces. Ukraine has been struggling to bolster its ranks after nearly three years of Russia's invasion, and the Ukrainian Legion, created for its nationals living abroad, is Kyiv's latest push to convince men of combat age to enlist. "I had to gather my strength," says construction manager Rusakevych, who has lived in Poland for over 30 years with his Polish wife and teenage son, adding, "I see that we are losing. Something must be done about it." IMAGES AND SOUNDBITES
