As with the United States Army, the United States Marine Corps (USMC) dates back to 1775 when the first battalions of men were formed under the command of Samuel Nicholas (1744-1790). Marines operate as part of the United States Navy and form the 'sea-borne infantry arm' of the American war machine - primarily assaulting enemy positions by way of amphibious means.
The USMC has participated in every major conflict since the inception of the United States of America including the Revolutionary War, the War of 1812, the Mexican-American War, the Civil War, World War 1, World War 2, Korea, Vietnam, the 1991 Gulf War, and - more recently - Iraq and Afghanistan. It was during World War 2 that the modern image of the fighting Marine was born, solidifying their place on the world stage for generations.
