What does the U.S. Marine Corps motto "Semper Fidelis" mean?

The motto "Semper Fidelis," often abbreviated to "Semper Fi," translates to "Always Faithful." This phrase encapsulates the commitment and loyalty that Marines vow to uphold, not only to their service, but also to each other and to the country. It serves as a reminder of the enduring support and dedication that is expected among members of the Marine Corps. This sense of loyalty is central to the identity and ethos of the Marines, emphasizing the importance of trust and camaraderie within the ranks. While the other choices capture various admirable qualities, they do not reflect the specific meaning and tradition behind the motto as accurately as "Always Faithful."
