Final answer:
The question relates to a specific policy in the United States Navy regarding the retention and transfer to the Fleet Reserve of Sailors based on their years of service and rate reduction. The information provided doesn't contain a direct answer, and the inquirer should consult the Naval Personnel Manual or a personnel officer for details.
Step-by-step explanation:
The original question posed pertains to the policies of the United States Navy concerning retention and transfer to the Fleet Reserve for Sailors who have completed certain years of service but have been reduced in rate before reaching 20 years of service. It's important to navigate official Navy regulations to find the answer to this policy-related question, although the question itself does not specify the exact number of years completed by the Sailor.
These regulations can be complex, detailing different scenarios under which Sailors can be retained or discharged. In the broader context of military personnel policy, the information provided about the shift in the National Guard's drill requirements and post-World War II demobilization illustrates the evolving nature of military commitments and composition over time.
The references provided do not contain specific answers to the question asked. Thus, the student might need to review the current Naval Personnel Manual (MILPERSMAN) or consult their command's personnel officer for the most accurate information relating to retention and fleet reserve transfer policies based on their years of service and change in rate. Given the nuanced nature of military law and regulations, direct access to updated service guidelines is required to provide a precise answer.
