(If you're interested in seeing a very well though-out war machine, type in turtle ship in a search engine and read up on it. Completely sealed off from invaders gaining access to the inside of their boats and those aboard (spiked top), 26 canons set at different ranges, ~130 people on board, chemical weapon, used for about 4 centuries)
In the beginning of the war, only the Axis used poison gas (mustard gas was the first kind to be used), but by the end of the war, both sides used poison gas as a weapon.

The use of mustard gas in World War One was a terrible and inhumane weapon. Gas masks were the best protection soldiers had to avoid breathing in this gas.
Hiroshima is known as the site of the first military use of an atomic weapon.
It was a weapon. Weapons are used in wartime quite a lot.

* Germany's first gas attack was in October of 1914, was ineffective and hardly noted. * Its first effective use was on 3 January 1915 against Russia. * The first use of gas in warfare was made by the French using tear gas without effect and little notice in August of 1914. * It required serious experimentation by both sides before it became a battlefield weapon, but improvement came with lethal effect.
To create a weapon the likes that the world has never seen.

Although Germany is generally conceived as the first country to use gas warfare, the French used tear gas in 1914 during WWI. After extensive study, Germany made a comeback by using mustard gas, among other lethal gases.
