In 1775, the Marine Corps was formed as the Continental Marines. They were specifically established to serve as an infantry branch that was able to engage in combat both on land and at sea during the American Revolutionary War. Today, members of the Marine Corps work closely with the Navy as well as the Army and the Air Force, gaining nicknames such as "America's third Air Force" and "America's second land Army." This 5" Circle Sticker can be used by former and current Marines to show pride in their branch. It can also be used by others to show support for the USMC.
