Commander, Naval Special Warfare Command Rear Adm. Collin Green relieved the three senior leaders of SEAL Team Seven from their positions Sept. 6.

Green relieved the unit’s commanding officer, Cdr. Edward Mason; executive officer, Lt. Cdr. Luke Im; and the team’s top enlisted leader, Command Master Chief Hugh Spangler due to a loss of confidence that resulted from leadership failures that caused a breakdown of good order and discipline within two subordinate units while deployed to combat zones.

SEAL teams conduct special operation missions in support of U.S. combatant commanders at forward locations throughout the world.
