AFAIK, the main reason gas wasn't used on the battlefield in WWII was because of its' limited tactical value. It can only be used if the enemy is down wind. Dispersion direction is hard to calculate, winds can suddenly shift and such. Also, the lingering effects makes it nigh impossible to use the speed element to secure the gassed area - you can't go in there either. In WWI, gas was used (at least by the germans) for areas intended to be enveloped, not assaulted directly.Originally posted by STEELER13
Yo All,
Actually I thought gas attacks were not used because of the mutual deterrence factor(although term is from Cold War, theory still applies). The fear was that once gas was used on the battlefield, there was no turning back and gas would be used by bombers against cities. From the late 1930's(following Italy's invasion of Ethiopia) many Europeans feared gas attacks on major cities. When war was declared September third, 1939, many citizens of London, Berlin and Paris carried gas masks with them. And when V2's were launched, the fear was that the Germans would attach gas warheads.
Would gas have changed things on a WWII battlefield? Depending how it was used, I think it could have, but not one worth the risk of the response.
Still, everyone expected and feared gas to be used, at least early in the war. Heck, we saw the same thing this very spring, didn't we? For strategical uses, like V rockets, city bombings and stuff, there might have been use for it. There, I think your argument of mutual deterrence applies.
