Founded in 1775, the United States Marine Corps (USMC) has a long and storied history of answering the nation’s call to duty. Renowned as the “first to fight,” Marines are meticulously trained to be a highly lethal and adaptable fighting force. But What Do Marines Do beyond the battlefield? This article explores the diverse roles and responsibilities that define the USMC, highlighting their commitment to service, both at home and abroad.
A Legacy of Honor and Courage
Since their inception, Marines have been at the forefront of American military history, participating in countless battles to safeguard national interests and uphold cherished ideals. From the historic Battle of Belleau Wood to modern-day operations in Afghanistan, the Marine Corps has consistently served as America’s expeditionary force in readiness. This enduring legacy is built upon a foundation of unwavering courage and a relentless fighting spirit. Marines are known for their grit and determination, pushing forward when others might falter. This heritage of valor and sacrifice is deeply ingrained in every Marine.
Core Values: Honor, Courage, Commitment
At the heart of the Marine Corps ethos are three core values: Honor, Courage, and Commitment. These principles serve as the bedrock of their actions and strengthen their resolve to achieve victory in any situation. “Honor” guides Marines to act ethically and responsibly in all aspects of their service. “Courage” empowers them to face adversity and danger head-on, both physically and morally. “Commitment” reflects their dedication to the mission, their fellow Marines, and the unwavering defense of the nation. These values forge an unbreakable bond among Marines and fuel their inner drive to succeed.
America’s Expeditionary Force in Readiness
The Marine Corps is uniquely structured and trained as “America’s expeditionary force in readiness.” This means they are prepared to rapidly deploy and respond to crises around the globe, offering agile and innovative warfighting capabilities across all domains—land, sea, air, space, and cyberspace. As a naval expeditionary force, Marines are often the first boots on the ground in contingency operations, providing a crucial initial response to threats against national security.
Operating as a Marine Air-Ground Task Force (MAGTF), the USMC provides a versatile and comprehensive range of response options for the Joint Force. MAGTFs integrate ground combat, aviation, logistics, and command elements, enabling them to deter aggression, defend national interests, and support humanitarian assistance and disaster relief efforts effectively. This integrated structure allows for rapid and sustained operations in diverse and challenging environments.
Diverse Roles and Military Occupational Specialties (MOS)
While every Marine is fundamentally a rifleman, trained for combat, the Marine Corps offers hundreds of specialized roles known as Military Occupational Specialties (MOS). These roles span a vast spectrum, from infantry and artillery to aviation, intelligence, communications, logistics, and cyber operations. Marines serve in diverse capacities, including providing security for American embassies and naval bases worldwide, participating in Marine Expeditionary Units (MEUs) for rapid crisis response, and undertaking special assignments as directed by the President. This breadth of expertise ensures the Marine Corps can effectively address a wide array of global challenges.

Global Presence and Primary Base Communities
The reach of the Marine Corps extends across the globe, with deployments and installations strategically positioned to protect American interests and respond to emerging threats. From Marine Expeditionary Units operating in critical maritime regions to Marine Security Guards safeguarding U.S. embassies, Marines maintain a constant global presence. Primary base communities within the United States and abroad support these operations, fostering readiness and providing essential infrastructure. Marine Corps Installations Command (MCICOM) oversees these installations, ensuring efficient resource management and operational effectiveness.
In conclusion, what do Marines do? They are defenders of freedom, expeditionary warriors, and global ambassadors. They are defined by their core values of Honor, Courage, and Commitment and stand ready to answer the nation’s call whenever and wherever they are needed. Whether engaging in combat, providing humanitarian aid, or maintaining global security, the US Marine Corps remains “always ready when our nation is least ready.”
