What is the title of the individual who oversees the Marine Corps as Commandant?

The Commandant of the Marine Corps is the highest-ranking officer in the United States Marine Corps and serves as the principal advisor to the President and the Secretary of Defense on Marine matters. This title signifies the top leadership position within the Marine Corps, responsible for overseeing the organization, readiness, and training of Marines. The Commandant acts as the spokesperson and representative for the Marine Corps and plays a crucial role in shaping military policy and strategy as it pertains to amphibious warfare and Marine operations.

Other titles listed, such as Chief of Staff, Major General, and Brigadier General, reference positions that have different responsibilities and ranks within the military hierarchy. The Chief of Staff typically refers to a senior officer managing staff functions but is not specifically tied to the Marine Corps command structure in the same way. Major General and Brigadier General are both ranks within the USMC, but neither position carries the overarching authority and responsibility that comes with being the Commandant of the Marine Corps.
