Which document provides instructions and references required for use in the 3-M System?

The document that provides instructions and references required for use in the 3-M System is OPNAVINST 4790.4(series). This instruction outlines the processes and responsibilities associated with maintenance management within the Navy's 3-M System, which encompasses the Maintenance, Material Management, and Maintenance Control functions.

In the context of the 3-M System, this instruction serves as a fundamental guideline for effective maintenance practices, detailing standards for maintenance scheduling, reporting, and documentation. It ensures that personnel involved understand their roles and the necessary procedures to maintain equipment and facilities efficiently and effectively.

Given the specific focus of the other options, such as OPNAVINST 3120.3(series) which pertains to the organization and administration of certain operational aspects, and OPNAVINST 5100.19(series) which addresses safety and health standards, they do not directly provide the comprehensive framework or guidance related to the 3-M System. Similarly, OPNAVINST 4441.170A focuses on logistics and supply operations rather than maintenance management specifically. Therefore, OPNAVINST 4790.4(series) is uniquely positioned as the correct choice for accessing the essential instructions and references for the 3-M System.
