Smoke munitions Japanese

The Japanese also used mustard for filling shells and bombs, primarily as a 50 50 mixture with Lewisite to lower the freezing point. Examples of Japanese chemical munitions are Artillery shells, 150 mm and 105 mm and Mortar rounds 90 mm, filled with either mustard gas /Lewisite mixture or diphenylcyanoarsine, and Artillery shells 75 mm filled with either phosgene or diphenylcyanoarsine. In addition there were 15 kg and 60 kg aerial bombs, toxic smoke candles and canisters filled with diphenylcyanoarsine. [12] Japan is estimated to have produced a total of around 1.7 million CW bombs and shells, and 5.7 million chemical candles and grenades. One source quotes the total amount of chemical munitions produced by Japan, regardless of agent fill, as approximately 7.4 million.[20] As already stated in an earlier paragraph, Chinese sources estimate that approximately 2 million of these rounds were abandoned in Northern China.[7]...
