Semper Fidelis is expressed as 'Always faithful' to which entities?

• A. Always faithful to the Nation and the Marine Corps
• B. Always faithful to the Nation, the Marine Corps, and fellow Marines
• C. Always faithful to fellow Marines
• D. Always faithful—to the Nation, the Marine Corps, and fellow Marines

Answer: (D)

Semper Fidelis means lifelong loyalty to three related obligations. First, to the Nation that authorizes service and sets the conditions for duty. Second, to the Marine Corps as the institution that trains, disciplines, and provides purpose. Third, to fellow Marines—the comrades with whom a Marine serves, fights, and relies on for mutual protection. The best formulation expresses fidelity to all three without leaving any piece out, because the strength of the Marines lies in their shared commitment to country, their service branch, and the brothers and sisters in arms who stand with them. The dash is only a stylistic choice; it doesn't change the meaning. So the intended answer is always faithful to the Nation, the Marine Corps, and fellow Marines.
