Object 37: U.S. Marine "Doughboy" Helmet from WWI
After the 1871 Corean Incident, the U.S. Marine Corps remained nearly continuously engaged in action around the world. This honed their tactics and techniques, and prepared them for their legendary battles in World War I. It was during this period that some of the Marine Corps' great heroes emerged. And when the Marines finally entered World War I, they did so wearing combat helmets for the first time.
