The United States Armed Forces[5] are the federal military forces of the
United States. They consist of the
Army,
Marine Corps,
Navy,
Air Force, and
Coast Guard.[6]
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.
The U.S. military is the largest military in the world in terms of number of personnel. It draws its manpower from a large pool of paid volunteers; although conscription has been used in the past in various times of both war and
peace, it has not been used since
1972.
As of 2016, the United States spends about $580.3 billion annually to fund its military forces and
Overseas Contingency Operations.[4] Put together, the United States constitutes roughly 39 percent of the world's military expenditures. For the period
2010–14,
SIPRI found that the United States was the world's largest exporter of major arms, accounting for 31 per cent of global shares. The United States was also the world's eighth largest importer of major weapons for the same period.[7] The U.S. Armed Forces has significant capabilities in both defense and power projection due to its large budget, resulting in advanced and powerful equipment, and its widespread deployment of force around the world, including about 800 military bases in foreign locations.[8]
History[edit]
Main article:
Military history of the United States
The history of the U.S. military dates to
1775, even before the
Declaration of Independence marked the establishment of the United States.
The Continental Army,
Continental Navy, and
Continental Marines were created in close succession by the
Second Continental Congress in order to defend the new nation against the
British Empire in the
American Revolutionary War.
These forces demobilized in 1784 after the
Treaty of Paris ended the
War for Independence.
The Congress of the
Confederation created the
United States Army on 3 June 1784, and the
United States Congress created the
United States Navy on 27 March 1794, and the
United States Marine Corps on 11 July 1798. All three services trace their origins to the founding of the
Continental Army (on 14 June 1775), the Continental Navy (on
13 October 1775) and the Continental Marines (on
10 November 1775), respectively. The 1787 adoption of the
Constitution gave the
Congress the power to "raise and support armies", "provide and maintain a navy", and to "make rules for the government and regulation of the land and naval forces", as well as the power to declare war. The United States
President is the U.S. military's commander-in-chief.
Rising tensions at various times with
Britain and
France and the ensuing Quasi-War and
War of 1812 quickened the development of the
U.S. Navy (established 13 October 1775) and the United States Marine Corps (established 10 November 1775). The U.S. Coast Guard dates its origin to the founding of the
Revenue Cutter Service on 4 August 1790; that service merged with the
United States Life-Saving Service in
1915 to establish the Coast Guard.
The United States Air Force was established as an independent service on
18 September 1947; it traces its origin to the formation of the
Aeronautical Division, U.S.
Signal Corps in 1907 and was part of the Army before becoming an independent service.
