There are many types of chemical weapons, some of these include mustard gas, chlorine gas, sarin, and tear gas. The results can leave humans disfigured and severely burned, almost to death. Death by mustard gas is described as especially horrible.

       One World War I nurse, Vera Brittain said, “I wish those people who talk about going on with this war no matter what the costs could see the soldiers suffering from mustard gas poisoning. Great mustard-coloured blisters, blind eyes, all sticky and stuck together, always fighting for breath, with voices a mere whisper, saying their throats are closing and they know they will choke.”

       The gases are extremely deadly, but even more than that they drive fear into the heart of the opposing forces. Seeing a massive cloud of gas moving towards you scares even the most experianced troops. Just as harmful are invisible, odorless gases. Seeing your comrades fall down and choke takes the nerve out of anyone, especially if they know they have been exposed to the same thing. More and more chemical weapons are produced each day.
