Senior petty officer grade, E-6, worn in both the Navy and Coast Guard as three chevrons below the eagle. First class petty officers commonly serve as leading petty officers of divisions, senior watch supervisors and instructors, and form the pool from which chiefs are selected.
Example: PO1 Grant, the division LPO, approved the watch bill for the in-port period.
