What are the four levels of maintenance?

• A. Unit, Direct support, Expanded support, Depot
• B. Unit, Direct support, General support, Depot
• C. Unit, General support, Direct support, Depot
• D. Field, Unit, Direct support, Depot

Answer: (B)

Maintenance is organized into four echelons, each with a specific role and scope of work that grows as you move up. The four levels are Unit maintenance, Direct Support maintenance, General Support maintenance, and Depot maintenance. Unit maintenance covers the repairs and servicing that a unit can handle with its own personnel and tools, aiming for quick fixes and to return equipment to operation fast. Direct Support maintenance sits at a level that supports one or more units and handles more complex repairs that the unit can’t do on its own, using more specialized capabilities. General Support maintenance provides broader, area-wide repair capability that can service multiple units and handle major overhauls or rebuilds that require more extensive expertise and resources. Depot maintenance is the highest level, performed at specialized facilities with the most advanced equipment and processes for complete overhauls and rebuilding of major systems. The correct choice lists these four levels in the standard order: Unit, Direct Support, General Support, Depot. The other options modify the set or use nonstandard terminology, which doesn’t align with the established maintenance echelon structure.
