However‚ this time‚ instead of being struck by a bomb‚ they were struck by a chemical warfare agent (CWA) known as sulfur mustard‚ which destroyed their home‚ murdered their newborn child‚ and resulted in weeks of intense medical care. The use of chemical weapons during World War One revolutionized chemical warfare. Since WW1‚ chemical weapons have grown in popularity. The experience with chemical weapons (CW) in WW1‚ the Northern Yemeni War‚ and Syria demonstrates why the production and
