>>in order to produce mass casualties in battlefield conditions, a chemical attacker has to deploy tons – and I mean that word literally – of this stuff. While I do agree with much of what this guy has to say about elephants, he is totally wrong about chemical weapons. We don't use mustard gas because it would indeed require tons of gas and be ineffective, but chemical weapons have evolved in the last 100 years . Mod…
Well, how much does it take to create a cloud of poisonous gas that is sufficiently concentrated to induce lethality and also spreads reasonably quickly that people can't escape it? Bret gives the example of the Tokyo terrorist attack that released sarin in several crowded subway cars... and killed 12 people. Grenades would have killed far more people far more quickly... and that's the point: chemical weapons are far…
But to simplify, cluster mutinous are more effective vs troops than a single large detonation. Similarly, rather than starting from a single source you want to spread the weapon from a large number of points. By comparison to 7mg/m3 a 1 metric ton weapon could ideally cover a square kilometer to a thickness of 30m and concentration of 30mg/m3.
Notably, exposure time plays a major role in lethality so covering a wider area makes it much harder to escape from.
