USMC

United States Marine Corp
The United States Marine Corps (USMC) is a branch of the United States armed forces responsible for providing force projection from the sea, using the mobility of the United States Navy to rapidly deliver combined-arms task forces. It is one of seven uniformed services of the United States. In the civilian leadership structure of the United States military, the Marine Corps is a component of the Department of the Navy, often working closely with U.S. naval forces for training, transportation and logistic purposes; however, in the military leadership structure the Marine Corps is a separate branch.

Captain Samuel Nicholas formed two battalions of Continental Marines on 10 November 1775 in Philadelphia as naval infantry. Since then, the mission of Marine Corps has evolved with changing military doctrine and American foreign policy. The Marine Corps served in every American armed conflict and attained prominence in the 20th century when its theories and practices of amphibious warfare proved prescient and ultimately formed the cornerstone of the Pacific campaign of World War II. By the mid-20th century, the Marine Corps had become the dominant theorist and practitioner of amphibious warfare. Its ability to respond rapidly to regional crises gives it a strong role in the implementation and execution of American foreign policy.
