The crew of the Coast Guard Cutter Tern, an 87-foot Marine Protector Class patrol boat homeported out of Coast Guard Sector San Francisco, gather for a group picture with their former commanding officer after a change-of-command ceremony, July 27, 2020. The change-of-command ceremony is a time-honored event preserved by the heritage of naval tradition. It is a custom that is formal, follows military protocol and is designed to strengthen the respect for the continuity of command that is vital to military organization.(U.S. Coast Guard photo by Petty Officer 1st Class Emma Croft)
