The Culture of the United States Marine Corps is widely varied, but unique amongst the branches of the United States armed forces. Because its members are drawn from across the United States (and resident aliens from other nations), it is as varied as each individual Marine, but tied together with core values and traditions passed from generation to generation of Marines. As in any military organization, the official and unofficial traditions of the Marine Corps serve to reinforce camaraderie and set the service apart from others. The Corps' embracement of its rich culture and history is cited as a reason for its high esprit de corps.
Many traditions and customs of the Corps are officially recognized through orders, histories, and ceremonies; some are even embodied within the uniform itself.
The Marine Corps Core Values of Honor, Courage, and Commitment have gained increased prominence in recent years. As an emphasis on performing morally on and off duty, the concept of core values has been infiltrated into many aspects of Marine life, beginning in recruit training and continuing into combat. This "warrior ethos" provides guidance to Marines in difficult ethical situations and acts as a reminder to provide good order and discipline.
The Marines' Hymn dates back to 1919 and is the oldest official song in the U.S. Armed Forces. It embraces some of the most important battles of the Corps at that time, including Chapultepec and Derna. Subtle changes and unofficial verses have been added as the history of the Corps grew.
The official Marine Corps emblem is the Eagle, Globe, and Anchor, sometimes abbreviated "EGA". Adopted in its present form in 1868 by Commandant Jacob Zeilin, it derives partially from ornaments worn by the Continental Marines and the British Royal Marines, and is usually topped with a ribbon reading "Semper Fidelis". The original eagle was a crested eagle found in the Americas, not the bald eagle that appears in the current emblem. The eagle stands on the Western Hemisphere and holds in its beak a scroll bearing the motto "Semper Fidelis", though the scroll is sometimes omitted from uniform insignia. An anchor fouled with rope stands behind the globe, and while it generally points to the left, it can be found reversed when paired so that the anchors continually face the other. The eagle stands for a proud country, the globe signifies worldwide service, and the fouled anchor signifies naval tradition.
