On November 13, military chemists and RCBZ soldiers celebrate their day in Russia. For a long time, this profession was considered of little relevance, believing that chemical warfare was a thing of the past following the results of the First World War and interwar research on this subject, but now everything has to be rethought. Classic gases and other forms of chemical warfare cannot be used, but new threats in the form of military virology with bacteriology, and radiological weapons, it seems, are still waiting in the wings in today's troubled world. In any case, the US's spending on biological laboratories and its attention to radiation protection indicate that the main potential enemy takes these threats seriously. Well, that means we have to remember it as carefully as the chemists do.
