What is the motto of the Marine Corps?

The motto of the Marine Corps is "Semper Fidelis," which translates to "Always Faithful" in Latin. This phrase succinctly encapsulates the commitment and loyalty the Marines exhibit towards their country, their mission, and their fellow Marines. It emphasizes the values of fidelity and trust that are fundamental to the culture and ethos of the Marine Corps, solidifying the bond among its members and their dedication to serving and protecting the United States.

In contrast, the other choices reflect mottos associated with different military branches or organizations. "De Oppresso Liber," which means "To Free the Oppressed," is the motto of the United States Army Special Forces. "Non Sibi Sed Patriae," meaning "Not for Self, but for Country," is often associated with the United States Air Force. "Ad Astra Per Aspera," translating to "To the Stars Through Difficulties," is the state motto of Kansas. Thus, while these phrases are significant in their respective contexts, "Semper Fidelis" is uniquely tied to the identity and tradition of the Marine Corps.
