What is the Marine Corps?

We are America's Expeditionary Force in Readiness - Response at a Moment's Notice

"The Marine Corps is the Nation’s expeditionary force in readiness. On a day to day basis, we are forward deployed, forward engaged, and prepared for crisis response. We are also ready to respond in the event of a major contingency. The American people have come to expect us to do what must be done “in any clime and place” and under any conditions. They expect us to respond quickly and to win.

Our expeditionary nature provides combatant commanders other options that are increasingly in demand. While Marines are naval in character and uniquely capable of coming from the sea, our expeditionary nature allows us to operate effectively in underdeveloped conditions ashore."

 

- General James Dunford

36th Commandant of the Marine Corps
