The Radiation, Chemical, Biological and Nuclear (RCBN) Defense Troops of the Support Forces Command of the Armed Forces of Ukraine have recorded more than 13,700 cases of Russian forces using hazardous chemical agents against Ukraine's Defense Forces since the start of the full-scale invasion.

Maksym Kravchuk, Spokesperson for the Support Forces Command, told Ukrinform.

According to Kravchuk, Russian troops continue to systematically employ hazardous riot-control chemical agents alongside conventional weapons. Nearly 200 such incidents were recorded in June 2026, compared with almost 250 in May.

"At present, the number of such attacks has declined, but it is difficult to predict the enemy's future actions," Kravchuk said.

He specified that Russian forces use K-51 and RG-Vo gas grenades, as well as improvised containers filled with CS and CN chemical agents. These substances are primarily delivered by unmanned aerial vehicles.
