Which source provides non-medical administrative material, including cleaning supplies?

SERVMART is the correct source for obtaining non-medical administrative material, including cleaning supplies. It is a retail supply establishment that offers a wide range of general supplies necessary for daily operations, such as office supplies, cleaning products, and other administrative resources. The purpose of SERVMART is to simplify the procurement of these types of items for military personnel, enhancing efficiency in ordering and inventory management.

Other options serve different functions; for instance, Medical Logistics focuses specifically on the procurement and distribution of medical items and equipment, which is outside the scope of non-medical administrative needs. The Supply Support Center is more involved in logistical support, including parts and repair supplies, primarily for maintenance operations, while the Fleet Supply Office coordinates broader supply chains and inventory management but does not specifically cater to general administrative materials like those provided by SERVMART.
