Astronaut badge

The astronaut badge is a badge of the United States, awarded to military pilots, naval flight officers, navigators/combat systems officers (this badge can also be awarded to USAF officer astronauts who are not navigators/CSOs, but who wear the same insignia while designated as astronaut-qualified Air Force "observers"), flight surgeons, and civilian pilots who have completed training and performed a successful spaceflight. A variation of the astronaut badge is also issued to civilians who are employed with the National Aeronautics and Space Administration as specialists on spaceflight missions.

Eligibility

To earn an astronaut badge, a military officer must complete all required training and participate in a space flight more than 100 kilometers (62 miles) above the Earth. This boundary, known as the Kármán line, comes from the Fédération Aéronautique Internationale. However, in the 1960s, the United States Department of Defense awarded astronaut badges to military and civilian pilots who flew aircraft higher than 50 miles (80 kilometres). Seven USAF and NASA pilots qualified for the astronaut badge by flying the sub-orbital X-15 rocket spaceplane. American test pilots Michael Melvill and Brian Binnie were each awarded a commercial astronaut badge by the Federal Aviation Administration (FAA) when they flew sub-orbital missions aboard the Scaled Composites SpaceShipOne rocket spaceplane. All other men and women awarded the astronaut badge earned it travelling to space in non-winged rockets, the X-15, or the Space Shuttle.

Air force

An air force, also known in some countries as an air army, is in the broadest sense, the national military organization that primarily conducts aerial warfare. More specifically, it is the branch of a nation's armed services that is responsible for aerial warfare as distinct from an army, navy, or a marine corps. Typically, air forces are responsible for gaining control of the air, carrying out strategic and tactical bombing missions, and providing support to land and naval forces.

The term "air force" may also refer to a tactical air force or numbered air force, which is an operational formation either within a national air force or comprising several air components from allied nations. Air forces typically consist of a combination of fighters, bombers, helicopters, transport planes and other aircraft.

Many air forces are also responsible for operations of the military space, intercontinental ballistic missiles (ICBM), and communications equipment. Some air forces may command and control other air defence assets such as anti-aircraft artillery, surface-to-air missiles, or anti-ballistic missile warning networks and defensive systems. Some nations, principally Russia, the former Soviet Union and countries who modelled their militaries along Soviet lines, have an air defence force which is organizationally separate from their air force.

Marines

Marines, also known as a marine corps and naval infantry, are an infantry force that specializes in the support of naval and army operations on land and at sea, as well as the execution of their own operations. In the majority of countries, the marine force is part of the navy, but it can also be under the army like the Troupes de marine (French Marines) and Givati Brigade (Israeli Marines), or form an independent armed service branch like the United States Marine Corps and Royal Marines.

Historically, tasks undertaken by marines have included providing protection from war while at sea, reflecting the pressed nature of the ships' company and the risk of mutiny. Other tasks would include boarding of vessels during combat or capture of prize ships and providing manpower for raiding ashore in support of the naval objectives.

With the industrialization of warfare in the 20th century the scale of landing operations increased; this brought with it an increased likelihood of opposition and a need for co-ordination of various military elements. Marine forces evolved to specialize in the skills and capabilities required for amphibious warfare.

Coast guard

A coast guard or coastguard is a maritime security organization of a particular country. The term implies widely different responsibilities in different countries, from being a heavily armed military force with customs and security duties to being a volunteer organization tasked with search and rescue functions and lacking any law enforcement powers. However, a typical coast guard's functions are distinct from typical functions of both the navy (a pure military force) and a transportation police (a civilian law enforcement agency).

History

The modern Her Majesty's Coastguard of the United Kingdom was established in 1809 as the Waterguard, and was originally devoted to the prevention of smuggling as a department of the HM Customs and Excise authority. It was, however, also responsible for giving assistance to shipwrecks.

Each Water Guard station was issued with Manby's Mortar which was invented by Captain George William Manby in 1808. The mortar fired a shot with a line attached from the shore to the wrecked ship and was used for many years up and down the coastline. This began the process in which the Coastguard assumed a life saving role. In 1821 a committee of inquiry recommended that responsibility for the Preventative Water Guard be transferred to the Board of Customs. The Treasury agreed and in a Minute dated 15 January 1822, directed that the preventative services, which consisted of the Preventative Water Guard, cruisers, and Riding Officers should be placed under the authority of the Board of Customs and in future should be named the Coast Guard. In 1845 the Coastguard was subordinated to the Admiralty.

United States Armed Forces

The United States Armed Forces are the federal military forces of the United States. They consist of the Army, Marine Corps, Navy, Air Force, and Coast Guard. The President of the United States is the military's overall head, and helps form military policy with the U.S. Department of Defense (DoD), a federal executive department, acting as the principal organ by which military policy is carried out.

From the time of its inception, the military played a decisive role in the history of the United States. A sense of national unity and identity was forged as a result of victory in the First Barbary War and the Second Barbary War. Even so, the Founders were suspicious of a permanent military force. It played an important role in the American Civil War, where leading generals on both sides were picked from members of the United States military. Not until the outbreak of World War II did a large standing army become officially established. The National Security Act of 1947, adopted following World War II and during the Cold War's onset, created the modern U.S. military framework; the Act merged previously Cabinet-level Department of War and the Department of the Navy into the National Military Establishment (renamed the Department of Defense in 1949), headed by the Secretary of Defense; and created the Department of the Air Force and National Security Council.
