More than a motto, a way of life

Semper Fidelis distinguishes the Marine Corps bond from any other. It goes beyond teamwork – it is a brotherhood and lasts for life. 
 
Latin for "always faithful," Semper Fidelis became the Marine Corps motto in 1883. It guides Marines to remain faithful to the mission at hand, to each other, to the Corps and to country, no matter what. 
 
Becoming a Marine is a transformation that cannot be undone, and Semper Fi reminds us of that. Once made, a Marine will forever live by the ethics and values of the Corps.  
 
There is no such thing as an ex-Marine.
