The Chemical Corps (also known as the "Dragons of the Battle") are the branch of the United States Army tasked with defending against chemical, biological, radiological, and nuclear (CBRN) weapons. The corps was founded as the U.S. Chemical Warfare Service (CWS) during World War I. Its name was changed to the Chemical Corps in 1946. For most of its history, the Chemical Corps was tasked with delivering chemical weapons rather than defending against them.
