The message identifies Andriy Dudka, a Ukrainian from Sumy, as a member of the RDK (Russian Volunteer Corps) and the Sokol organization, which promotes social nationalism. He is noted for posing with a group under a flag associated with social nationalists and national socialists, and for posting a poem on May 9 about the Third Reich's defeat and revenge. No event of killing, capture, or arrival in Ukraine is explicitly stated, so the default event type is 'arrived'.
