What position does Carlos Ruiz hold?

The position of Sergeant Major of the Marine Corps is the highest enlisted rank in the United States Marine Corps. It serves as the principal advisor to the Commandant of the Marine Corps on matters involving enlisted personnel. This role requires extensive experience and knowledge of the Marine Corps, making it a significant leadership position that impacts policy and morale within the enlisted ranks. Carlos Ruiz, holding this position, would be expected to embody the ideals and standards of the Marine Corps while advocating for the concerns of enlisted Marines.

It's important to recognize that the other roles listed, such as the Commander of Naval Service Training Command or Master Chief Petty Officer of the Navy, pertain to different branches or organizations within the Navy and Marine Corps. Each of these positions has its own distinct responsibilities and areas of focus, differing from the overarching enlisted advisory role that comes with being the Sergeant Major of the Marine Corps. The NJROTC Director, likewise, focuses on Naval Junior Reserve Officers' Training Corps programs but does not hold the same level of authority or influence over the Marine Corps as the Sergeant Major does.
