U.S. Navy Capt. Peter A. Ruocco returns a salute and departs from the 1st Dental Battalion change of charge ceremony at Camp Pendleton, Calif., Aug. 16, 2017. During Ruocco’s departure, the sideboys render their honors as the boatswain “pipes” Ruocco ashore. The Boatswain's pipe is traditionally used to pass commands to the crew as the sound of the crew or bad weather would drown out a Sailors voice. (U.S. Marine Corps photo by Lance Cpl. Joseph Sorci)
