The Command Master Chief’s Challenge Coin sits atop a folded U.S. flag at the U.S. Coast Guard Atlantic Area Command Master Chief Change of Watch ceremony in Portsmouth, Virginia, on June 6, 2022. Challenge coins are used as unofficial awards by command staff to show appreciation and unit morale. The ceremony is rich in military history to allow subordinates to witness the formality of command change from one leader to another. (U.S. Coast Guard photo by Auxilarist Andrew Winz)
