The Commandant of the Marine Corps (CMC) is normally the highest-ranking officer in the United States Marine Corps and is a member of the Joint Chiefs of Staff. The CMC reports directly to the United States Secretary of the Navy and is responsible for ensuring the organization, policy, plans, and programs for the Marine Corps as well as advising the President, the Secretary of Defense, the National Security Council, the Homeland Security Council, and the Secretary of the Navy on matters involving the Marine Corps. Under the authority of the Secretary of the Navy, the CMC designates Marine personnel and resources to the commanders of Unified Combatant Commands. The Commandant performs all other functions prescribed in Section 5043 in Title 10 of the United States Code or delegates those duties and responsibilities to other officers in his administration in his name. As with the other joint chiefs, the Commandant is an administrative position and has no operational command authority over United States Marine Corps forces.
Marine biology is the scientific study of marine life, organisms in the sea. Given that in biology many phyla, families and genera have some species that live in the sea and others that live on land, marine biology classifies species based on the environment rather than on taxonomy.
The United States Armed Forces are the military forces of the United States of America. It consists of the Army, Marine Corps, Navy, Air Force, and Coast Guard.

The Battle of Iwo Jima was a major battle in which the United States Marine Corps landed on and eventually captured the island of Iwo Jima from the Imperial Japanese Army (IJA) during World War II. The American invasion, designated Operation Detachment, had the goal of capturing the entire island, including the three Japanese-controlled airfields, to provide a staging area for attacks on the Japanese main islands.

The Great Barrier Reef is the world's largest coral reef system composed of over 2,900 individual reefs and 900 islands stretching for over 2,300 kilometres (1,400 mi) over an area of approximately 344,400 square kilometres (133,000 sq mi). The reef is located in the Coral Sea, off the coast of Queensland, Australia. The Great Barrier Reef can be seen from outer space and is the world's biggest single structure made by living organisms. This reef structure is composed of and built by billions of tiny organisms, known as coral polyps. It supports a wide diversity of life and was selected as a World Heritage Site in 1981. CNN labelled it one of the seven natural wonders of the world. The Queensland National Trust named it a state icon of Queensland.
The Corps of Royal Marines (RM) is the amphibious light infantry and one of the five fighting arms of the Royal Navy. The Royal Marines were formed in 1755 as the Royal Navy's infantry troops. However, the marines can trace their origins back to the formation of the English Army's "Duke of York and Albany's maritime regiment of Foot" at the grounds of the Honourable Artillery Company on 28 October 1664.
The Marine Raiders were elite units established by the United States Marine Corps during World War II to conduct special amphibious light infantry warfare, particularly in landing in rubber boats and operating behind the lines. "Edson's" Raiders of 1st Marine Raiders Battalion and "Carlson's" Raiders of 2nd Marine Raiders Battalion are said to be the first United States special operations forces to form and see combat in World War II.

Marines, also known as naval infantry, are typically an infantry force that specializes in the support of naval and army operations at sea and on land and air, as well as the execution of their own operations. In many countries, the marines are an integral part of that state's navy. In others, it is a separate organization altogether, such as in the United States, where the Marine Corps falls under the US Department of the Navy, yet it operates independently. Marines can also fall under a country's army like the Troupes de marine and Givati Brigade.
United States Marine Corps Forces Special Operations Command (MARSOC) is a component command of the United States Special Operations Command that comprises the Marine Corps' contribution to SOCOM. Its core capabilities are direct action, special reconnaissance and foreign internal defense. MARSOC has also been directed to conduct counter-terrorism, and information operations.
The Uniforms of the United States Marine Corps serve to distinguish Marines from members of other services. Among current uniforms in the United States Armed Forces, the Marine Corps dress uniforms have been in service the longest. The Marine Dress Blue uniform has, with few changes, been worn in essentially its current form since the late 19th century.
