Sustainment (military)


Military logistics is the discipline of planning and carrying out the movement and maintenance of military forces. In its most comprehensive sense, it is those aspects or military operations that deal with:

The word "logistics" is derived from the Greek adjective logistikos meaning "skilled in calculating". The first administrative use of the word was in Roman and Byzantine times when there was a military administrative official with the title Logista. At that time, the word apparently implied a skill involved in numerical computations.

Historically supplies for an army were first acquired by foraging or looting, especially in the case of food and fodder, although if traveling through a desolated region or staying in one place for too long resources could quickly be exhausted. A second method was for the army to bring along what was needed, whether by ships, pack animals, wagons or carried on the backs of the soldiers themselves. This allowed the army some measure of self-sufficiency, and up through to the 19th century most of the ammunition a soldier needed for an entire campaign could be carried on their person. However this method led to an extensive baggage train which could slow down the army's advance and the development of faster-firing weapons soon outpaced an army's ability to supply itself. Starting with the Industrial Revolution new technological, technical and administrative advances led to a third method, that of maintaining supplies in a rear area and transporting them to the front. This led to a "logistical revolution" which began in the 20th century and drastically improved the capabilities of modern armies while making them highly dependent on this new system.
