Which element is considered a part of sustainment logistics?

Sustainment logistics refers to the processes that support the continuous supply and maintenance of goods and services necessary for operations. This includes ensuring that equipment remains operational and functional throughout its life cycle. Maintenance is a crucial element of sustainment logistics because it encompasses activities required to keep equipment and vehicles in proper working order, including repairs, inspections, and servicing. By ensuring that all operational capabilities are maintained effectively, units can remain mission-ready and sustain their operational tempo.

Planning, although important, aligns more with the overall logistics strategy rather than being a direct part of sustainment logistics. Dismissal does not pertain to logistics at all, and finance, while integral to the logistics process in managing resources, does not specifically address the maintenance aspect. Thus, maintenance stands out as the direct answer in the context of sustainment logistics, emphasizing its role in operational readiness and support.
