Storekeepers that fall under the authority of a supply officer are attached permanently or temporarily to a supply department, either ashore or afloat. There are exceptions to this practice as was the case of the Independent Storekeeper NEC which trains E-5 and above to operate independent of a supply officer, such as, or while deployed with surface or aviation units that operate in remote areas where no supply officer is present. Additionally, in Aviation Squadrons, the storekeeper falls under the chain of command of the Aircraft Maintenance Officer and his designate; the Maintenance Material Control Officer. The best example of this is the Storekeeper(s) tasked with operating the
Naval Air Station Sigonella Weapons Department in
Sicily,
Italy. 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. ==Rank and recognition==
