Which command provides technical guidance and administrative assistance to Ships Stores under authority from NAVSUP?

The correct choice is NEXCOM, which stands for Navy Exchange Service Command. NEXCOM is responsible for providing operational support and guidance for Navy Exchanges and Ships Stores. This includes managing retail operations, ensuring compliance with regulations, and offering training and resources to personnel involved in managing retail services at sea and ashore. Their role emphasizes the importance of supporting the morale and welfare of Navy personnel through effective retail services.

Understanding the function of NEXCOM in relation to Ships Stores is vital, as it directly impacts the operations and success of these retail outlets. Authorization by NAVSUP, or Naval Supply Systems Command, facilitates NEXCOM's initiatives in offering this necessary support.

The other options, while related to Navy logistics and support services, do not have the primary focus on directing and assisting Ships Stores. COMNAVSUP is the command that oversees NAVSUP, which manages supply chain systems; DFAS (Defense Finance and Accounting Service) is responsible for financial management, while NAVSUP focuses on overall supply systems but does not directly provide the specialized support that NEXCOM offers to Ships Stores. Thus, NEXCOM is specifically designated to address the unique needs and operations of Ships Stores under the authority granted by NAVSUP.
