Final answer:
To address the situation where a Sailor lacks the needed 12 months for an Exchange of Duty, they should seek approval for an Exchange of Duty with another eligible Sailor, with necessary endorsements and approvals. If this is not possible, they may consider submitting a request for early transfer or extending their current sea tour.
Step-by-step explanation:
When a Sailor does not have 12 months remaining on their current prescribed sea tour to complete the required time aboard for an Exchange of Duty, they should seek approval for an Exchange of Duty. This involves coordinating with another Sailor who is both eligible and willing to exchange duty stations. The process of an Exchange of Duty requires proper endorsement and approval from commanding officers and detailers. If this option is not feasible, then alternatives such as submitting a request for an early transfer or extending the current sea tour may be considered, depending on the Sailor's circumstances and the needs of the Navy.
