What are the two maintenance levels described in the material?

• A. Field and sustainment
• B. Depot and sustainment
• C. Field and depot
• D. Sustainment and depot

Answer: (A)

Maintenance levels show where repairs are done and how complex the work is. The material describes two levels: field maintenance and sustainment maintenance. Field maintenance is performed close to the equipment, at the unit level, by technicians who handle routine servicing, basic troubleshooting, minor repairs, and component replacements that don’t require extensive tools or facilities. Sustainment maintenance sits above field and covers more complex diagnostics, repairs, and component rebuilds that field crews can’t complete, often at more capable shops or mobile support teams. It acts as the bridge between field work and the deeper capabilities of depot-level repair.

So the two levels described are field and sustainment because they reflect the near-site, day-to-day work and the higher-echelon work that requires more resources, without invoking the full depot overhaul. Depot-level maintenance is a separate, more intensive capability outside what the material is describing as the two levels.
