Resident of Vorkuta. In August 2024, he was taken off a train while returning from holiday with his family. He was then detained on charges of calling for extremism and terrorism and involvement in terrorist activities. The case is based on his emotion-filled online postings and a message addressed to his son, a Russian serviceman, to whom Kalashnikov sent a video of the Russian Volunteer Corps with the words "Let's go to RVC!". On May 22, 2025, Kalashnikov was sentenced to 15 years in a strict regime colony.
