The primary role of the Marine Corps in the 21st century is to be America's Expeditionary Force in Readiness. We are a force that provides combined-arms operating forces - including integrated aviation and logistical components - for service as part of naval, joint, and combined forces worldwide. The Marine Corps fills a unique role in the capability range of America's armed forces.  

As the nation's Middleweight/Crisis Response Force, we are lighter than the Army, and heavier than Special Operations Forces (SOF). Our Corps' forces magnify the United States' power-projection capabilities, to ensure American military power remains influential during peacetime, compelling in crisis, and decisive in war.

As we look ahead, we will reinvigorate and reinforce our credentials as a lighter, faster, hard-hitting, expeditionary, and sea-based Marine Corps that relies on agility, shock, and surprise. Innovation and fiscal responsibility will also continue to be hallmarks of the Marine Corps. We will continue to invest limited resources to restore combat capability and enhance our Marines' readiness at home and in overseas operating areas. We also are monitoring our total investment requirements and measuring them against changing operational demands. For example, in the Marine Corps' ground and aviation programs, we continue to test, develop, and procure dual-use systems and employ emerging technology. However, our focus remains on the individual Marine's ability to carry out the tasks at hand.

The Programs Section of Concepts and Programs contains the information on Marine Corps programs of record and major end-item equipment, which will ensure that current and future Marines have what they need to accomplish their mission.

  • About Concepts and Programs

    The vision of the Concepts and Programs project is to provide political and military leaders with timely, accurate, and relevant information. The Concepts and Programs project is the premier strategic communications vessel the Marine Corps relies on to inform Congress, the Office of Secretary of Defense, Chairman of the Joint Chiefs of Staff, and Think Tanks about the Corps’ vision.
