Missions have changed over the years, but what has remained constant since November 10, 1775 is our unyielding commitment to protecting the lives of our citizens and the interests of our nation. Our purpose, by congressional mandate, is to be this nation's rapid response force; we are thus called to be "most ready when the nation is least ready." From humanitarian relief efforts to combat operations; from air, land and sea to every clime and place, the Marine Corps is ready to answer our nation's call.
We make Marines. We win our nation's battles. We develop quality citizens. These are the promises the Marine Corps makes to our nation and to our Marines. They are the reason for our demanding recruit training process. They form our reputation as America's force in readiness and are honored through the reciprocal commitment, between the Marine and Marine Corps, expressed in our motto: SEMPER FIDELIS.
Every Marine is a rifleman, trained first as a disciplined warrior regardless of military occupational specialty. This training is key to our philosophy of maneuver warfare. Maneuver warfare combines operational positioning with firepower, demands agile forces capable of quick decision making, and employs the human elements of war—boldness, creativity, intelligence and the warrior spirit. Our combined arms approach multiplies the Marine Corps' strengths by bringing our land, air and sea forces together to achieve every mission. This organization creates a scalable force with incomparable warfighting capabilities. It is the key to winning battles.
