An expert on the dead Russian OSINT researcher Nemek has revealed confirmation of the death of Russian Armed Forces Colonel Andrei Ronchuk as a result of a Ukrainian attack on command posts in Donetsk on August 26. Ronchuk served as the Chief of Engineering Troops of the Central Military District of the Russian Armed Forces. At the same time, Rumchuk does not appear among the names of the 20 Russian officers killed in the attack and confirmed by Mediazona - which means that the real number of dead may be higher than is currently known.
