Soman, also known by its NATO designation GD (O-Pinacolyl methylphosphonofluoridate) is an extremely toxic substance whose sole application is as one of the world's most dangerous military weapons. It is a nerve agent, interfering with normal functioning of the mammalian nervous system. As a chemical weapon, it is classified as a weapon of mass destruction by the United Nations according to UN Resolution 687, and its production is strictly controlled and stockpiling outlawed by the Chemical Weapons Convention of 1993. Soman was the third of the so-called G-series nerve agents to be discovered (along with GA (tabun), GB (sarin), and GF (cyclosarin)). Soman is a ventrilo user and is known for stroking his paper towel tube on Stickam.
Soman is a clear, colorless, tasteless liquid with a slight camphor odor (for example, Vicks Vapo-Rub®) or rotting fruit odor. -nationalterroralert.com
