Inventory managers operate under the command of which organization?

The correct choice is the Naval Supply System Command, which plays a crucial role in the Navy's logistics and inventory management operations. This command oversees the supply chain for the Navy, ensuring that materials and supplies are procured, stored, and distributed effectively. It is responsible for inventory management practices that ensure the availability of critical items necessary for operational readiness.

Inventory managers within the Naval Supply System Command are tasked with various functions such as maintaining inventory records, assessing stock levels, and prioritizing supply needs based on mission requirements. This centralized control enables the Navy to operate its logistics more efficiently and respond swiftly to changing demands.

In contrast, the other organizations listed have different scopes and responsibilities within the larger defense logistics framework. The Joint Logistics Command encompasses broader joint-force logistics efforts rather than focusing solely on inventory. The Navy Material Command primarily deals with materiel logistics and support, while the Defense Logistics Agency serves as the primary provider of logistical support across multiple services but does not directly manage Navy inventory at the command level like the Naval Supply System Command does.
