General guidelines for retirement ceremonies are found in which resource?

The correct choice is the Naval Military Personnel Manual, as it contains specific guidance and instructions related to personnel policies, including the conduct of retirement ceremonies. This manual serves as an authoritative source for the Navy, detailing various standard practices and procedures that must be followed during official events such as retirement ceremonies. It addresses elements such as protocol, the roles of participants, and ceremonial customs, ensuring that such significant events are conducted with the appropriate decorum and professionalism expected in military settings. The other resources do not focus specifically on retirement ceremonies; the Uniform Code of Military Justice encompasses legal codes, Department of Defense Directives cover broader defense policies, and the Military Retirement Handbook may contain useful information but is not the primary authoritative source like the Naval Military Personnel Manual.
