Who orders Navy Wide Advancement Exams for LDO purposes with an approved request?

The process of ordering Navy Wide Advancement Exams for Limited Duty Officer (LDO) purposes is primarily initiated by the member's command. This means that the commanding officer or the appropriate personnel at the member's command is responsible for submitting the approved request for these exams. The member's command is closely involved in the promotion and advancement process and ensures that the selected candidates for the LDO program meet the necessary qualifications before requesting the examination.

This flow of responsibility emphasizes the command's role in managing personnel advancement within the Navy. In contrast, other options represent levels of personnel management and administration that may be involved in broader policy or procedural oversight but do not directly place the order for exams. Therefore, it is the immediate command that acts upon the readiness and qualifications of its personnel to advance, making this option the correct choice.
