U.S. Coast Guard Capt. Michael F. Nasitka and Cmdr. Mark A. McDonnell salute each other signaling the change of command for Coast Guard Cutter Campell Saturday, April 8, 2017, at Portsmouth Naval Station in Kittery, Maine. The Change of Command Ceremony is a time-honored military tradition conveying to officers and enlisted personnel of the cutter that the authority of command is relinquished by one person and assumed by another.
