The Navy Secret of the Marines

Although they operate as a distinct branch, the U.S. Marines are technically a part of the Department of the Navy. This unique relationship allows them to function as a self-contained force that can project power from the sea to the land.

While the Marines have their own infantry and aviation units, they rely on the Navy for transport and medical support during missions. They specialize in amphibious warfare, which means they are designed to launch attacks from ships directly onto foreign shores. This hybrid structure is what makes them the primary expeditionary force for the country. It is a rare example of two different branches working under a single administrative umbrella to maximize military efficiency.
