What is the official mission of the Marine Corps?

The official mission of the Marine Corps emphasizes its role as a highly trained, organized, and equipped force primarily focused on offensive amphibious operations. This mission reflects the Corps’ historical strengths and capabilities, particularly the ability to project power from the sea while maintaining readiness to respond rapidly to crises. The term "Force in Readiness" captures the essence of the Marine Corps, which is designed to be prepared for immediate action in diverse environments, making it a critical element of the United States' military strategy.

A mission centered on amphibious employment highlights the Marine Corps' unique operational focus compared to other branches, such as the Army or Air Force. While peacekeeping and diplomatic functions are important, they are not the primary mission of the Marine Corps. Therefore, the emphasis on offensive amphibious capabilities and readiness accurately portrays the essential purpose of the Marine Corps within the broader context of national defense and military operations.
