Final answer:
A Chief Petty Officer in the United States Navy wears three stars arranged in a diagonal line on their sleeve.
Step-by-step explanation:
A Chief Petty Officer (CPO) in the United States Navy wears three stars arranged in a diagonal line on their sleeve. Each star represents a rank of the CPO, which is one of the senior enlisted ranks in the Navy. The CPO is responsible for leading and supervising junior enlisted personnel.
The three stars on the CPO sleeve are referred to as the CPO rating badge. The rating badge is worn on the left sleeve of the enlisted service uniform, dress uniform, and dinner dress uniform jackets.
The rating badge is designed to indicate the rank and rating of the sailor. In addition to the three stars, the rating badge also displays the sailor's rating, which represents their job specialty in the Navy. The specific design and color of the rating badge vary depending on the sailor's rating and community within the Navy.
