The publication that defines official correspondence as all written material, documents, publications, charts, messages, and so forth, that are addressed to or sent from a command is indeed SECNAV M-5216.5. This manual provides comprehensive guidance on correspondence procedures and establishes the criteria and formats for official correspondence within the Marine Corps and other naval commands.

This definition encompasses a broad range of materials, highlighting that official correspondence goes beyond mere letters or memos to include various forms of written communication that are vital for command operations. Understanding this scope is crucial for anyone involved in the processing and handling of official documents within the Marine Corps, ensuring that they can effectively identify and manage the correspondence that falls under this definition.

The other publications mentioned, such as OPNAVINST 3120.32, SECNAVINST 5210.11, and MARADMIN 5000, focus on different aspects of Navy and Marine Corps operations and administration, but they do not specifically encompass the comprehensive definition of official correspondence as articulated in SECNAV M-5216.5.
