The United States Marine Corps specialty is the execution of naval landings. In this role, the corps played a key role in the Pacific during World War II. Nowadays, Marine troops usually fight alongside ground troops of the U.S. Army as mechanized infantry. USMC soldiers areoften on the toughest stretches of combat.

On February 19, 1945, the landing on Iwo Jima was led by the Marines. The first task was to occupy the airport and then seize Mount Suribachi, from where the Japanese carried out a heavy shelling.

A photo of a group of Marines clotting an American banner at the summit of Suribachi has become one of the most significant and recognizable images of the war.
