What do Standard Subject Identification Codes (SSIC) primarily indicate?

Standard Subject Identification Codes (SSIC) serve as a systematic coding mechanism that categorizes the subjects of naval documents. Each SSIC is represented by a four or five-digit number, which allows for the efficient organization and retrieval of documents within the Navy's documentation system. This structured approach aids in ensuring that information is easily accessible and helps personnel find relevant documentation pertaining to specific subjects or topics.

The primary function of SSICs is to maintain a consistent reference framework for naval communications, thereby allowing personnel to quickly reference the subject matter of documents without confusion. This is crucial in promoting clarity and standardization across various naval operations and administrative tasks. Conversely, the other options do not accurately describe the purpose of SSICs, which are specifically focused on identifying document subjects.
