Military logistics is the discipline of planning and carrying out the movement, supply, and maintenance of military forces. In its most comprehensive sense, it is those aspects or military operations that deal with: Design, development, acquisition, storage, distribution, maintenance, evacuation, and disposition of materiel. Transport of personnel. Acquisition or construction, maintenance, operation and disposition of facilities. Acquisition or furnishing of services. Medical and health service support. The word "logistics" is derived from the Greek adjective logistikos meaning "skilled in calculating", and its corresponding Latin word logisticus. In turn this comes from the Greek logos, which refers to the principles of thought and action. Another Latin root, log-, gave rise around 1380 to logio, meaning to lodge or dwell, and became the French verb loger, meaning "to lodge". Around 1670, the French King Louis XIV created the position of Maréchal des logis, an officer responsible for planning marches, establishing camp sites, and regulating transport and supply. The term logistique soon came to refer to his duties. It was in this sense that Antoine-Henri Jomini referred to the term in his Summary of the Art of War (1838). In the English translation, the word became "logistics". In 1888, Charles C. Rogers created a course on naval logistics at the Naval War College. In Farrow's Military Encyclopedia (1895), Edward S. Farrow, and instructor in tactics at West Point provided this definition:Bardin considers the application of this word by some writers as more ambitious than accurate. It is derived from Latin logista, the administrator or intendant of the Roman armies. It is properly that branch of the military art embracing all the details for moving and supplying armies. It includes the operations of the ordnance, quartermaster's, subsistence, medical, and pay departments. It also embraces the preparation and regulation of magazines, for opening a campaign, and all orders of march and other orders from the general-in-chief relative to moving and supplying armies.
