well maybe u need to research a little more considering under the chain of command the marines fall under the navy dude. heres a little excerpt you to think upon.
Marines (from the English adjective marine, meaning of the sea, from Latin language mare, meaning sea, via French adjective marin(e), of the sea) are, in principle, seaborne land soldiers that are part of a navy. However, in some countries, Marines are no longer part of the navy, notably the United States Marine Corps, which has become an independent armed force falling only administratively under the navy.
