What are the levels of maintenance?

• A. Field and sustainment
• B. Depot and organizational
• C. Intermediate and unit
• D. Global and local

Answer: (A)

The idea being tested is how maintenance work is organized by location and scope. In this framework, there are two levels: field maintenance, which is done at or near the unit to keep equipment running through troubleshooting and minor repairs, and sustainment maintenance, which covers more extensive repairs and overhauls at higher-echelon facilities away from the front line. This two-level view matches how repairs are typically separated into immediate, on-site support versus broader, deeper repair capability at centralized shops or depots. The other options mix terms that don’t fit this two-level framework.
