Our operating forces are a crisis response expeditionary force, task organized, and able to conduct operations across the entire spectrum of military operations. We maintain a constant state of readiness through an organizational structure that enables rapid, global response by air, land, and sea. Fundamentally, our Corps is a “middleweight force” that fills the void in our Nation’s defense structure between light Special Operations Forces (SOFs) and heavier conventional units. Our Corps provides scalable and adaptive forces, which complements both lighter and heavier forces.

Over the last several years, while we have become leaner in size, the Active Component (AC) Marines continue to reflect a U.S. Marine Corps, which is ready to meet the demands of global commitments and combat operations. Within this time of restructuring, we continue to maintain balanced, combined arms capabilities, which are adapted to the new demands of regional conflicts. We also continue to develop agile and capable forces to meet future hybrid threats. The same will be true of our Corps as it adjusts to post-Iraq and post-Afghanistan environments, which will include a capabilities based force, and adapting to the complex environment, while retaining the flexibility and agility to respond to future needs. The Organization outlines our combined arms structure and highlights the unique capabilities that Marines bring to the fight.

  • 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.
