What is the official symbol of the United States Marine Corps?

The official symbol of the United States Marine Corps is the Eagle, Globe, and Anchor. This emblem represents the core values and mission of the Corps. The eagle symbolizes the United States, as it is the national bird, while the globe signifies the Marine Corps' commitment to protecting national interests around the world. The anchor reflects the Marine Corps' naval heritage and its long-standing relationship with the U.S. Navy. Together, these three elements embody the spirit, tradition, and purpose of the Marine Corps, highlighting its role as an elite fighting force within the U.S. military.

In contrast, the Sword and Shield is associated more with the concept of defense and combat readiness, while the Star and Stripes is the national flag of the United States, rather than a specific symbol for any one branch of the military. The Lion and Tusk does not represent any known affiliation with the Marine Corps or its values. Thus, the Eagle, Globe, and Anchor distinctly represent the identity and mission of the United States Marine Corps, making it the correct choice.
