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. Australia In Australia each of the three independent Services of the Australian Defence Force (ADF) have different definitions for a 'Logistics Officer'. Logistics officers lead and coordinate planning and execution of the operations support components of the military effects which include the administrative (1) and logistics (4) functions, as well as major enabling support in the capability support dimension of force generation. Royal Australian Navy (RAN) logisticians are called a supply officer, the commissioned element of the Supply Branch. RAN "Loggies" conduct the non-technical component of 1/4 support effects. Australian Army logisticians are commissioned officers in the Australian Regular Army (ARA) or Army Reserve (ARES) normally drawn from the Ordnance (RAAOC), Transport (RACT), Catering (RAACC), Engineer (RAE), Electrical and Mechanical Engineer (RAEME), or Medical (RAAMC) corps. Army defines engineering as a subset of logistics. Royal Australian Air Force (RAAF) logisticians are called Logistics Officers (LOG), the commissioned element of the Logistics Employment Group (LEG). As in the RAF they are generally focused on the maintenance of the supply chain (in both Joint and Air environments), equipment governance, catering, movements and transport, the non-technical logistics disciplines. Unlike the Army RAAF "Loggies" work in parallel to RAAF engineers (Aeronautical [AERO], both Ground and Air Electrical [ELECTR], Armament [ARM] and Airfield [AFENG]) who comprise the specialist technical engineering and maintenance components of the RAAF integrated logistics workforce. LOG and ENG personnel (except AFENG) are managed by Logistics Branch - Air Force within Air Force Headquarters (AFHQ). AFENG are managed by the RAAF's Headquarters Combat Support Group. Additionally unlike their Navy and Army counterparts RAAF "Loggies" don't manage administrative, personnel or finance functions which are provided
