Deputy chief of mission
A deputy chief of mission is the number-two diplomat assigned to an embassy or other diplomatic mission. The deputy chief of mission is usually considered the second-in-command to the head of mission. DCMs serve as chargé d'affaires when the titular head of mission is outside the host country or when the post is vacant.
A DCM typically serves as a key advisor to the chiefs of mission as well as a chief of staff, and is responsible for the day-to-day management of the post. A DCM oversees the heads of sections at the embassy. They may also serve as de facto ombudsmen, responding to employee concerns and quality of life issues. Most career ambassadors have served as a DCM prior to their first assignment as chief of mission.
