Final answer:
Nuclear-trained Sailors will submit HYT waiver requests to their commanding officer or the appropriate authority within the Navy.
Step-by-step explanation:
Nuclear-trained Sailors will submit High Year Tenure (HYT) waiver requests to their commanding officer or the appropriate authority within the Navy.
HYT waivers are usually granted to allow Sailors to continue serving beyond their mandated service limits, if there is a critical need for their specialized skills.
In the case of nuclear-trained Sailors, who are highly trained in operating and maintaining nuclear systems on board Navy ships, their expertise is crucial to the mission readiness and effectiveness of nuclear-powered vessels.
