Who is authorized to assign the "Mandatory" priority level?

The correct answer is that the 3MC (Maintenance Material Control Officer) is authorized to assign the "Mandatory" priority level. This role is critical within the Navy’s 3-M System, as the 3MC is responsible for overseeing maintenance, material, and logistics within their area of operation. Assigning a "Mandatory" priority signifies the urgent necessity of addressing a maintenance requirement to sustain safety, readiness, or operational capability; thus, only the individual with the appropriate authority and oversight, such as the 3MC, can make this designation. This ensures that all maintenance priorities are aligned with the overall mission and safety requirements of the Navy.

In contrast, while roles like DIVO (Division Officer), LCPO (Leading Chief Petty Officer), and DH (Department Head) play important parts in the organization’s maintenance processes, they typically do not have the delegated authority to assign "Mandatory" priorities, which is specifically reserved for those in the 3MC position who have a comprehensive understanding of the 3-M System and its operational impact.
