The fire direction center (FDC) concept was developed at the Field Artillery School at Ft. Sill, Oklahoma, during the 1930s under the leadership of its Director of Gunnery, Carlos Brewer and his instructors, who abandoned massing fire by a described terrain feature or grid coordinate reference. They introduced a firing chart, adopted the practice of locating battery positions by survey, and designated targets with reference to the base point on the chart. In the spring of 1931, the Gunnery Department successfully demonstrated massing battalion fire using this method, which was used extensively by field artillery during World War II.
