13 press briefing.A total of 4,800 incidents involving chemical weapons, including tear gas and chemical agents typically intended for riot control, have been documented against Ukrainian forces since the war began, said Vlasiuk, who serves with the Support Forces’ Radiation, Chemical, and Biological Protection Command, at a briefing in Kyiv.Russian forces deliberately conceal their use of such weapons under the cover of "intense artillery, rocket, and bomb attacks," making it difficult to track, collect samples, and investigate these violations for prosecution against Russia.In an interview with the Kyiv Independent in October, Vlasiuk said the lack of specific equipment has hindered the Ukrainian military’s ability to identify new or mixed types of gases and develop effective protective measures for its personnel.He added that since the invasion began, more than 2,000 servicemen showing symptoms of chemical poisoning have been treated in military and civilian medical facilities for varying levels of exposure to known or unidentified substances.
