This historical monograph is one of a series of active duty and Reserve regimental histories. This series covers each regiment in the Fleet Marine Force. The narrative highlights the significant activities of the 14th Marines and offers a general history of the Marine Corps activities in which it participated. This particular monograph was assigned to a member of Mobilization Training Unit (History) DC-7, an organization composed entirely of Reservists tasked with augmenting the activities of the History and Museums Division, Headquarters, U.S. Marine Corps. These Reservists provide skills as historians, artists, and curators as part of their MW duties and stand ready to be called to active duty if needed. The 14th Marines is the artillery regiment assigned to the 4th Marine Division, the ground combat arm of the select Marine Corps Reserve. As such the 14th Marines represents one-quarter of the direct support and almost all of the general support heavy artillery in the Marine Corps. A Brief History of the 14th Marines is a concise narrative of the regiment, including its brief service during the World War I era, its proud service in the Pacific during World War II, and its reactivation and reorganizations since 1962. Official records of the Marine Corps and appropriate historical works were used in compiling this short history. This monograph is published for the information of those interested in the 14th Marines and the events that shaped its history.
