"Soman is a human-made chemical warfare agent classified as a nerve agent. Nerve agents are the most toxic and rapidly acting of the known chemical warfare agents. They are similar to pesticides (insect killers) called organophosphates in terms of how they work and the kinds of harmful effects they cause. However, nerve agents are much more potent than organophosphate pesticides. [...] Soman was originally developed as an insecticide in Germany in 1944. [...] Soman is also known as 'GD.' [...] Soman is a clear, colorless, tasteless liquid with a slight odor similar to camphor containing mothballs or rotten fruit. It can become a vapor if heated."
