Their responsibilities generally include purchasing and procurement, shipping and receiving, and issuing of equipment, tools, consumable items or anything else obtained through the Federal Stock System.

The best example of this is the Storekeeper(s) tasked with operating the Naval Air Station Sigonella Weapons Department in Sicily, Italy.

[citation needed] The department, a semi-autonomous entity within NAS Sigonella, is headed by a weapons officer to whom the Storekeepers report.

Since there is no supply officer within a weapons department either ashore, or afloat, the tasks of material control, inventory control, financial accounting, material custody, issuing, receiving and warehousing and disposition actions all fall within the storekeeper's scope of work, validating, initiating and signing requisitions falls upon the Independent Storekeeper.
