Army engineering maintenance

Army engineering maintenance consists of those engineers, technicians, and military organizations responsible for the expert repair and maintenance of army vehicles, weapon systems, and other equipment.

Army engineering maintenance should not be confused with military engineering which is distinctly separate and analogous to civil engineering while the former analogous to mechanical engineering and electrical engineering.

At the operational and tactical levels, army engineering maintenance is focused on the repair and scheduled maintenance work required to keep army equipment fleets operational.

At the strategic level, army engineering maintenance is closely linked to military logistics. At this level, it includes work such as the design, development, and testing of new vehicles and weapon systems. It also includes lifecycle management activities once new systems become operational.
