What is the title of the Commandant of the Marine Corps?

The title of the Commandant of the Marine Corps is indeed held by General Eric Smith. As the Commandant, he is responsible for all aspects of the Marine Corps, including its administration, training, and operations. This role is one of the highest positions in the United States Marine Corps and is typically held by a four-star general. The Commandant serves as the principal military advisor to the Secretary of the Navy and is primarily involved in strategizing the future development and employment of Marine Corps forces.

The other individuals listed have distinct titles and roles within the Navy and Marine Corps but do not hold the position of Commandant. For instance, the Sergeant Major of the Marine Corps is the senior enlisted advisor, while the Master Chief Petty Officer is a senior enlisted rank in the Navy, and the Admiral is a high-ranking naval officer, but not the Commandant of the Marine Corps. Understanding these distinctions can enhance knowledge about military structure and command.
