Emblem of the United States Marine Corps

The United States Marine Corps (USMC), also referred to as the United States Marines, is a branch of the United States Armed Forces responsible for conducting expeditionary and amphibious operations with the United States Navy as well as the Army and Air Force. The U.S. Marine Corps is one of the four armed service branches in the U.S. Department of Defense (DoD) and one of the seven uniformed services of the United States.

The Marine Corps has been a component of the U.S. Department of the Navy since 30 June 1834, working closely with naval forces. The USMC operates installations on land and aboard sea-going amphibious warfare ships around the world. Additionally, several of the Marines' tactical aviation squadrons, primarily Marine Fighter Attack squadrons, are also embedded in Navy carrier air wings and operate from the aircraft carriers.

The history of the Marine Corps began when two battalions of Continental Marines were formed on 10 November 1775 in Philadelphia as a service branch of infantry troops capable of fighting both at sea and on shore. In the Pacific theater of World War II the Corps took the lead in a massive campaign of amphibious warfare, advancing from island to island. As of 2017, the USMC has around 186,000 active duty members and some 38,500 reserve Marines. It is the smallest U.S. military service within the DoD.

Selected quote

Charles C. Krulak.jpg

"Sound morals and ethical behavior cannot be established or created in a day, a semester … or a year. They must be institutionalized our character over time. They must become a way of life. They go beyond our individual services and beyond our ranks or positions. They cut to the heart and soul of who we are and what we are and what we must be: men and women of character.

They arm us for the challenges to come and impart to us a sense of wholeness. They unite us in the calling we now know as the profession of arms. Of all the moral and ethical guideposts that we have been brought up to recognize, the one that, for me, stands above the rest. The one that I have kept in the forefront of my mind . . . is integrity."

— General Charles C. Krulak, USMC (Retired), January 27, 2000
