What are the two levels of Army maintenance?

The correct answer highlights the two primary levels of Army maintenance as Field and Sustainment. Field maintenance occurs at the unit level and involves tasks such as routine servicing, troubleshooting, and making minor repairs. This level is essential for maintaining equipment in an operational state, allowing units to perform their missions effectively without significant downtime.

Sustainment maintenance, on the other hand, takes place at designated facilities and is focused on more extensive repairs, overhauling, and rebuilding of equipment. This level of maintenance is crucial for ensuring long-term readiness and serviceability of equipment, providing the necessary support to keep the Army operational.

Understanding these two levels is vital as they define the structure and capabilities available for maintaining equipment throughout its lifecycle. This systematic approach ensures that both immediate and strategic maintenance needs are met efficiently.
