Work at PMC "Wagner". Evgeny Prigozhin, Dmitry Utkin and others. The book “My Call Sign “Martin”” consists of two parts. The first part - “In the same river twice” - was published in 2022 in Russia in an abridged version, it tells about the participation of Russian legionnaires in the civil war in Syria. In Germany, the first part was published in its entirety. The second part of the book – “The Advisor” – is a continuation of the first. Here the author talks about how he was Yevgeny Prigozhin’s assistant and how he left the Wagner PMC. Published in Germany. Published for the first time. Marat Gabidullin. Born in 1966 in the city of Sterlitamak, Bashkir Autonomous Soviet Socialist Republic, he spent his entire childhood in Uzbekistan in the city of Zarafshan. After graduating from school in 1984, he entered the Ryazan Higher Military Airborne School, from which he graduated in 1988. He served in the Airborne Forces until 1993 and was dismissed due to a bureaucratic error. In 1994, he came into conflict with the leader of a criminal group, spent three years in prison, and was released in 1997. In 2015, he joined the ranks of the Wagner PMC and went from an ordinary soldier to the commander of a reconnaissance company. After being seriously wounded near Palmyra in 2016, he was appointed assistant chief of staff of the assault detachment. In September 2017, he worked for four months in Prigozhin’s central office as an assistant supervisor of the Wagner PMC for tactical situations. Throughout 2018, he served as senior adviser to the Syrian ISIS Hunters battalion; in February 2019, he retired from the Wagner PMC. The first time I tried to publish a book about the Wagner PMC was in 2020, but due to threats from the Wagner PMC security service, I refused to publish it. The book “The Same River Twice” was published in early 2022. Currently lives in France.
