United States. Marine Corps

Founded on November 10, 1775, the United States Marine Corps began as the Continental Marines during the American Revolution. Today it serves as a separate military branch within the Department of the Navy, with a long-standing role in deploying quickly by sea, air, and land.

The Marines are especially associated with expeditionary and amphibious operations, combining infantry, aviation, artillery, and special operations capabilities in a force designed to move fast and fight in difficult conditions. Over time, that mission has helped shape the Corps' strong public identity and its reputation for toughness, training, and unit pride.

Because this is an institution rather than a single author, there is no individual biography in the usual sense. Still, its history, traditions, and distinctive role in U.S. military life have made the Marine Corps the subject of many memoirs, histories, and firsthand accounts.
