Cmdr. John J. Christensen, incoming Commanding Officer of Coast Guard Cutter Seneca, addresses a crowd during the change of command ceremony, Thursday, May 24, 2018, in Boston, Massachusetts. The change-of-command ceremony is a time-honored military tradition aboard ships and shore commands and signifies a total transfer of responsibility, authority, and accountability from one individual to another.
