“ Brigadier General Oleksandr Tarnavskyi, who at the beginning of the summer resigned from the post of commander of the operational-tactical group “Donetsk” and commander of the 9th Army Corps, returns to the position of head of the corps. OTU “Donetsk” as a temporary body was liquidated within the framework of the corps reform. Source: two interlocutors of the UP in the Defense Forces Details: At the beginning of June, 55-year-old Oleksandr Tarnavskyi, as far as the UP knows, left both positions, allegedly due to health problems. He was replaced by the Chief of Staff of the 9th Corps – 50-year-old Major General Viktor Nikoliuk. From time to time, he could be seen in the photographs of the chief of missions to the Pokrovsky direction, where the 9th corps operates. Nikoliuk in the 1st and 3rd photos next to Syrskyi Tarnavskyi returned to his former position the other day, and Nikoliuk, as learned by UP, was appointed by Syrskyi as the commander of another – the 20th corps, which operates on the border of Donetsk and Dnipropetrovsk regions. Nikoliuk in the 20th Corps took the place of Colonel Maksym Kitugin, who was removed from his post due to the breakthrough of the Russians into the Dnipropetrovsk Region. For reference: Tarnavskyi is best known as the commander of the “Tavria” anti-aircraft missile defense system during the difficult and, unfortunately, unsuccessful offensive of the Defense Forces in the Melitopol direction in the summer of 2023. Then the Ukrainian army, attacking in a pre-announced direction with weak intelligence and planning, spent three long months on breaking through the first line of enemy defense in the Robotyny region. And within a year, Robotyne was back under the control of the enemy. In December 2024, Tarnavskyi assumed a new position – the commander of the 9th corps and the OTU “Donetsk” attached to this corps. In March 2025, the UP reported that since the appointment of Tarnavskyi, he had replaced at least eight brigade commanders in his area of responsibility. Two of them are convinced that Tarnavsky himself initiated their release. Read also: Will Ukraine fight in corps? Analysis of UP Background: In June, UP wrote that Tarnavskyi, who commanded the “Donetsk” operational-tactical group of troops, which includes a number of the most difficult areas of the front in Donetsk region, in particular Pokrovsk, resigned from his post. Major General Viktor Nikoliuk became the new commander of “Donetsk” at that time.”, — write: www.pravda.com.ua
