Which document outlines the policies and procedures for the Navy 3-M System?

The correct answer is significant because OPNAVINST 4790.4E specifically pertains to the policies and procedures associated with the Navy's Maintenance Material Management (3-M) system. This instruction details how to achieve and sustain effective maintenance support across the naval operations, influencing how equipment and systems are managed within the fleet.

OPNAVINST 4790.4E integrates guidance on maintenance planning, performance assessments, and records management, ensuring a comprehensive approach to maintenance functions. Understanding this directive is essential for personnel involved in maintaining operational readiness and ensuring compliance with established standards.

The other documents may cover different aspects of naval operations or maintenance, but they do not provide the core framework and detailed protocol for the 3-M system specifically as OPNAVINST 4790.4E does. This distinction highlights why it's essential to reference the correct instruction for understanding the 3-M system thoroughly.
