Chiefs Cover Newly promoted Navy Chief Sarah Powers looks up as she receives a chief petty officer cover during a pinning ceremony aboard the amphibious assault ship USS Bataan at sea, Sept. 16, 2016. Powers is an aviation boatswain’s mate-handler. The pinning ceremony marks the end of "Chief's Season," and is a tradition unique to the Navy that signifies the chief petty officer's transition into new leadership roles and responsibilities.
