What are the two levels of maintenance?

• A. General Maintenance and Depot Maintenance.
• B. Field Maintenance and Sustainment Maintenance.
• C. Local Maintenance and Depot Maintenance.
• D. Primary Maintenance and Secondary Maintenance.

Answer: (B)

Two levels of maintenance describe how repair work is organized to keep equipment ready for operations. Field maintenance is the hands-on, in-the-field work performed by unit technicians to handle routine servicing, fault isolation, and minor repairs so systems stay operational without returning to a depot. Sustainment maintenance covers more complex repairs, overhauls, and refurbishment needed to restore or extend readiness during ongoing operations, typically at higher-level facilities or sustainment depots. This split lets units fix what they can quickly and escalate the rest to a level equipped for deeper work, ensuring equipment remains mission-capable over time. Other terms mix different echelons and don’t reflect this standard two-tier arrangement.
