Description

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 ##### ######### 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.
