What criteria does the Naval Military Personnel Manual provide information on?

The Naval Military Personnel Manual outlines critical information regarding personnel policies and procedures, including guidelines for retirement eligibility. This manual serves as a comprehensive resource for understanding the criteria that service members must meet to retire, such as age, years of service, and other relevant factors. It plays a vital role in helping personnel navigate their entitlements and benefits upon completing their service.

In contrast, while the other options touch on significant topics within the Navy or military context, they do not fall under the purview of the Naval Military Personnel Manual. Information regarding deployments, medical discharges, and chain of command structure is more likely found in separate documents or manuals that focus specifically on operational guidance, medical policies, and command structure, rather than on retirement specifics.
