A logistics officer is a member of an armed force or coast guard responsible for overseeing the support of an army, air force, marine corps, navy or coast guard fleet, both at home and abroad. Logistics officers can be stationary on military bases or deployed as an active part of a field army, air wing, naval force or coast guard fleet. The responsibilities of Logistics Officers vary, depending on where they are deployed and what tasks they are assigned. In addition, different countries have different roles for Logistics Officers. The main role of these officers remains the same regardless of where they are stationed; to ensure that the force is supplied with enough food, water, fuel, ammunition and other goods and services to complete the task at hand.
