MILPERSMAN 1810-020 outlines the process for officers requesting voluntary retirement from active duty. Officers must submit requests via the Navy Standard Integrated Personnel System (NSIPS) and follow specific timing guidelines for submission. The request must be made 6 to 12 months before the desired retirement date, depending on whether it aligns with the projected rotation date. Exceptions can be granted under certain circumstances. All retirement requests are subject to approval by Navy Personnel Command.
