April 22, 2015 marked the 100th anniversary of the beginning of chemical warfare at Flanders Fields in France. After World War I German forces first used chlorine gas on British, French, Canadian and Algerian forces on April 22, 1915, chemical weapons went on to claim tens of thousands of lives throughout the remainder of the war. The Army's Chemical Warfare Service was established, June 28, 1918, to manage chemical offensive and defensive chemical weapons programs. Today, 85 percent of the active Army's chemical, biological, radiological, nuclear and explosive (CBRNE) capabilities are part of the Aberdeen Proving Ground, Maryland-based 20th CBRNE Command.
