What type of documents should have "by direction" authority limited to within the Marine Corps?

The designation of "by direction" authority is specifically intended for routine documents within the Marine Corps context. This means that these documents can be signed by a subordinate on behalf of a superior officer, indicating that the action or correspondence is being conducted under the authority granted by that superior. Routine documents typically encompass communications that are standard in nature and do not involve sensitive or classified information, thereby making it appropriate to limit this authority within the Marine Corps environment.

Routine documents include things like administrative paperwork, reports, or internal communications that require timely responses but do not have significant implications beyond day-to-day operations. By restricting "by direction" authority to these documents, the Marine Corps ensures that more sensitive communications, such as legal or confidential documents, maintain the necessary level of oversight and authority, safeguarding the integrity and security of the information shared.
