Rear Adm. Dave Callahan, commander of 8th Coast Guard District, pins a departing award on Capt. Peter Martin, commander of Sector Houston-Galveston, during a change-of-command and retirement ceremony at San Jacinto College in Houston, Apr. 24, 2017. The change-of-command ceremony is a time-honored, military tradition that conveys to officers and enlisted personnel that although the authority of command is relinquished by one person and assumed by another, it is still maintained without interruption.
