The division takes its name from the shoulder sleeve insignia designed for a 1917 training camp contest by American regionalist artist Marvin Cone, who was then a soldier enlisted in the unit. Cone's design evoked the desert training grounds of Camp Cody, New Mexico, by superimposing a red steer skull over a black Mexican water jug called an "olla." In World War I, the unit was called the "Sandstorm Division." German troops in World War II, however, called the U.S. division's soldiers "Red Devils" and "Red Bulls," the division later officially adopted the divisional nickname Red Bulls.
