When Russia’s invasion of Ukraine ignited into war, back in Moscow, a young Russian who now goes by the name of Karabas was plunged into despair. Shocked by images of what was happening to Ukrainians in Russian-occupied areas, he decided to act — against Russia, his home and country.

Karabas said he knew that what he was doing was drastic. He packed his bags and decided to find a way to get to Ukraine to join the ranks of Kyiv’s troops fighting Russian forces.

It took him almost a year to make it happen.

Today, he is part of the Siberian Battalion, a unit made up of Russians who have joined Ukrainian military ranks to fight against their homeland, hoping someday to help oust Russian President Vladimir Putin. Its members hail mostly from ethnic minorities from Russia’s far east.
