What document categorizes and classifies Navy and Marine Corps records?

The Standard Subject Identification Code Manual (SSIC) is the correct choice because it establishes the system for categorizing and classifying records within the Navy and Marine Corps. This manual provides a standardized method for organizing and managing documents, allowing for easier retrieval and reference. The SSIC system helps ensure that all personnel can identify and access records consistently, fostering efficiency in administrative processes.

In contrast, while the Records Management Manual also deals with the management of records, it does not specifically define the categorization system used for Navy and Marine Corps records. Document Control Guidelines focus on the processes related to controlling documents rather than their classification. The Field Manual for Administrative Procedures provides guidelines for conducting administrative tasks but lacks a structured classification system for records. The SSIC is specifically tailored for this purpose, making it the most appropriate answer for the question at hand.
