"Phosgene poison, in my opinion, if I am not mistaken now. The people do not know what to do with it, to be honest. Such a nasty thing. I have now graduated from tactical medicine at the military academy, and there was just a case at the front line with this gas. That is, a very sad experience," the officer said.
Phosgene was actively used as a chemical compound warfare agent during World War I and has a suffocating effect.
