The Military of the United States, officially known as the United States Armed Forces, is structured into five branches consisting of the:
Approximately 1,426,713 personnel are currently on active duty in the military with an additional 1,259,000 personnel in the seven reserve components (53,000 of whom are in the Army and Air National Guard).[6] As it is currently a volunteer military, there is no conscription. Women are not allowed to serve in some combat assignments, but they are allowed to serve in most non-combat specialties. Due to the realities of war some of these non-combat positions see combat regularly. [7] Much of U.S. military capability is involved in logistics and transportation, which enable rapid buildup of forces as needed. The Air Force maintains a large fleet of C-5 Galaxy, C-17 Globemaster, and C-130 Hercules transportation aircraft with an equally large fleet of aerial refuelling tankers. The Marine Corps maintains Marine Expeditionary Units at sea with the Navy's Atlantic and Pacific Fleets. The Navy's fleet of 11 active aircraft carriers, combined with a military doctrine of power projection, enables a flexible response to potential threats. For these reasons, the United States military is universally considered the most powerful in the world. The United States Army is not as expeditionary as the Marine Corps, but Army Chief of Staff General Peter Schoomaker has announced a reorganization of the Army's active-duty units into 48 brigade groups with an emphasis on power projection. There will be three classes of brigade group: light, medium, and heavy, with a different mix of armored and infantry units. In Army reorganization, however, battalions will still be affiliated with traditional regiments, and brigades will still be affiliated with traditional divisions. Reorganized brigades began operation in Iraq in the third quarter of 2005.
Organization
Under the President is the United States Secretary of Defense, a Cabinet Secretary responsible for the Department of Defense. Both the President and Secretary of Defense are advised by the Joint Chiefs of Staff composed of the service chiefs and led by the Chairman of the Joint Chiefs of Staff and the Vice Chairman of the Joint Chiefs of Staff. The Goldwater-Nichols Department of Defense Reorganization Act of 1986 (PL 99-433) reworked the command structure of the United States military, introducing the most sweeping changes to the United States Department of Defense since it was established in the National Security Act of 1947. The Goldwater-Nichols Reorganization Act was signed into law by President Ronald Reagan on October 1, 1986. The Goldwater-Nichols Act streamlined the military chain of command, which now runs from the President through the Secretary of Defense directly to unified combat commanders, bypassing the Joint Chiefs of Staff, who were assigned to an advisory role. Each service is responsible for organizing, training and equipping military units for the commanders of the various Unified Commands.

Unified Combatant CommandsThere are 10 Unified Combatant Commands: 6 geographic and 4 functional.
Until 2007, five geographical commands were given responsibilities for United States military operations in various areas of the world as shown on the following map.

As of mid- 2006, nearly 150,000 U.S. troops are currently deployed in the Middle East.[citation needed] Most of these forces are currently engaged in Operation Enduring Freedom in Afghanistan, and Operation Iraqi Freedom in Iraq. Within the United StatesIncluding U.S. territories and ships afloat within territorial waters A total of 1,112,684 personnel are on active duty within the United States including:
Types of PersonnelJunior EnlistedAfter enlistment, new Army recruits undergo Basic Combat Training (BCT), followed by schooling, referred to as Advanced Individual Training (AIT), in their primary Military Occupational Specialty (MOS) at any of the numerous MOS training facilities around the world. Other branches may use different terminology; for example, Air Force Basic Military Training graduates attend Technical Training, colloquially called "Tech School," and upon completion are awarded an Air Force Specialty Code (AFSC) at the apprentice (3) skill level. Initially, recruits without higher education or college degrees will hold the paygrade of E-1, and will be elevated to E-2 usually after the completion of Basic Combat Training and with a minimum of six months Time-In-Service (TIS). Different services have different incentive programs for enlistees, such as higher initial ranks for college credit and referring friends who go on to enlist as well. With parent/guardian permission, applicants can enlist at the age of 17 and participate in the Delayed Entry Program (DEP). In this program, the applicant is given the opportunity to participate in locally sponsored military-related activities, which can range from sports to competitions (each recruiting station DEP program will vary), led by recruiters or other military liaisons. Participation in this programs is an example of the different opportunities the recruits have to elevate in rank before their departure to Basic Combat Training. There are several different authorized paygrade advancement requirements in each junior enlisted rank category (E-1 to E-4), which differ by service. Enlistees in the Army can attain the initial paygrade of E-4 (Specialist) with a full four-year degree, but the highest initial entry paygrade is usually E-3. Promotion through the junior enlisted ranks is generally noncompetitive, with promotions occurring upon attaining a specified number of years of service, a specified level of technical proficiency and maintenance of good conduct. Noncommissioned OfficerWith very few exceptions, the only direct path to the non-commissioned officer ranks in the United States military are through the lower enlisted ranks. Unlike promotion through the lower enlisted tier, promotion through the NCO ranks are generally competitive. NCO ranks begin at E-4 (E-5 in the Air Force and, with some exceptions, the Army) and are generally attained at between three and six years of service. Junior noncommissioned officers (pay grades E-4, E-5 and E-6) function as front line supervisors, squad leaders, and technical experts, training the junior enlisted in their duties and guiding their career advancement. Senior Noncommissioned OfficerWhile by law considered part of the non-commissioned officer corps, senior noncommissioned officers referred to as Chief Petty Officers in the Navy and Coast Guard perform duties more focused on leadership rather than technical expertise. Promotion to the SNCO ranks (E-7 through E-9) is highly competitive. Manning at the pay grades of E-8 and E-9 are limited by Federal law to 2% and 1% of a service's enlisted force respectively. SNCOs function as leaders of small units and staff functions. Some SNCOs manage programs at headquarters level, and a select few wield responsibility at the highest levels of the military structure. All SNCOs are expected to mentor junior commissioned officers as well as the enlisted in their duty sections. The typical enlistee can expect to attain SNCO rank at between 13 and 18 years of service. Each of the five services employs a single senior enlisted advisor at departmental level. This individual is the highest ranking enlisted member within his (no females have yet been so appointed) respective service and functions as the chief advisor to the service secretary, service chief of staff, and Congress on matters concerning the enlisted force. These individuals carry responsibilities and protocol requirements equivalent to general and flag officers. They are:
OfficerThere are five common ways for one to receive a commission as an officer in one of the branches of the U.S. military (although other routes are possible).
Officers receive a commission assigning them to the Officer Corps from the President (with the consent of the Senate). Through their careers, officers usually will receive further training at one or a number of the many U.S. military staff colleges. Company grade officers (pay grades O-1 through O-3) function as leaders of smaller units or sections of a unit, typically with an experienced SNCO assistant and mentor. Field grade officers (pay grades O-4 through O-6) lead significantly larger and more complex operations, with gradually more competitive promotion requirements. General officers, or flag officers, serve at the highest levels and oversee major portions of the military mission, from base command on up. Warrant OfficerAdditionally, all services except for the U.S. Air Force have an active Warrant Officer corps. Above the rank of Warrant Officer One, these officers are also commissioned officers, but usually serve in a more technical and specialized role within units. More recently though they can also serve in more traditional leadership roles associated with the more recognizable officer corps. With one notable exception, these officers ordinarily have already been in the military often serving in senior NCO positions in the field in which they later serve as a Warrant Officer as a technical expert. The exception to the NCO rule is the case of helicopter and fixed wing pilots in the U.S. Army; although most Army pilots have indeed served some enlisted time, it is also possible to enlist, complete basic training, go directly to the Warrant Officer Candidate school at Fort Rucker, Alabama, and then on to flight school. The Air Force ceased to grant warrant officer commissions in 1959 when the grades of E-8 and E-9 were created. Most non-flying duties performed by warrant officers in other services are instead performed by senior NCOs in the Air Force. History[11]Prior to and during the founding of the United States, military forces were supplied by untrained militia commanded by the states. When the Continental Congress first ordered a Continental Army to be formed, it was to be made up of militia from the states. That army, under the command of General George Washington, won the Revolutionary War, but afterwards was disbanded. However, it soon became obvious that a standing army and navy were required. The United States Navy began when Congress ordered several frigates in 1794, and a standing army was created, however it was still only minimal and it relied mostly on contributions from state militia in times of war. Between the founding of the nation and the Civil War, American military forces fought and won against Barbary Coast pirates; fought the War of 1812 against the British, which ended in the status quo; and won several southwestern territories from the Mexicans in the Mexican-American War. In 1861, with the beginning of the Civil War, many military forces, including the nation's best generals, became part of the Confederate military, and both armies fought a long, bloody struggle which consumed 600,000 lives and ended in Union (U.S.) victory in 1865. In the period between the Civil War and the 1890s, the military was allowed to languish, although units of the U.S. Army did fight Native Americans as settlers moved into the center of the United States. By the end of the century, though, America was rapidly becoming a new superpower. The military fought the Spanish-American War and the Philippine-American War, along with several Latin American interventions, and Teddy Roosevelt sent the Great White Fleet around the world in a display of American power. In addition, the Militia Act of 1903 established the National Guard. The United States entered World War I in 1917 and played a minor role in the Allied victory. It languished in the interwar period, but as tensions mounted leading up to World War II, the force was put back into shape. U.S. Army troops were a large component of the forces that took North Africa, Italy, and landed in France at D-Day, and U.S. Navy, Marine, and Army troops were heavily involved in Pacific campaign against Japan and its allies. The end of World War II was the start of the Cold War, a large but ultimately non-violent struggle between the United States and its NATO Allies and the Soviet Union and its Warsaw Pact allies. Thousands of U.S. troops were deployed to Europe in anticipation of a struggle that never came. However, U.S. troops did participate in proxy wars in Korea and Vietnam. The Korean War, with North Korea and China against South Korea, the U.S., and other UN troops, ultimately returned to the status quo. The Vietnam War between North Vietnam and South Vietnam and the U.S., was ultimately a failure, resulting in U.S. pullout and unification of the country under communism. In the 1980s, the U.S. military fought Operation Just Cause in Panama and Operation Urgent Fury in Grenada. In addition, the Goldwater-Nichols Act completely reorganized the military. By 1989, it was clear the Soviet Union was on the verge of collapse and it looked like the U.S. military would be left with no one to fight. However, when Iraq invaded Kuwait in 1991, the United States entered the Persian Gulf War. The military forces of the U.S. and other nations easily defeated the Iraqi Army with minimal losses, proving the combat readiness of the new all-volunteer military. After this brief war and the breakup of the Soviet Union, the U.S. military had relatively little to do throughout the remainder of the 1990s, barring interventions in Yugoslavia and Kosovo. After the September 11th terrorist attacks in 2001, U.S. military forces were an integral part of the War on Terror. U.S. and NATO forces invaded Afghanistan in 2001, and in 2003 the U.S. and several other countries invaded Iraq. While the initial invasion was successful, the occupation quickly bogged down after the defeat of the conventional Iraqi forces, with daily violence and terrorist attacks. However, some milestones have been reached, such as the capture and execution of Saddam Hussein and democratic elections. ExpendituresImage:Military expenditure percent of GDP.PNG Military spending as a percentage of GDP The military expenditure of the United States Department of Defense for fiscal year 2006 is:
The United States military budget is larger than the military budgets of the next twenty largest spenders combined, and six times larger than China's, which places second. The United States and its closest allies are responsible for approximately two-thirds of global military spending (of which, in turn, the U.S. is responsible for the vast majority). Military spending accounts for 19% of the United States' federal budget, and approximately half of its federal discretionary spending, which comprises all of the U.S. government's money not accounted for by pre-existing obligations.[2] [13] However, in terms of per capita spending, the U.S. ranks third behind Israel and Singapore[14]. It is also number 26 in terms of military spending per dollar GDP. [15] According to the Stockholm International Peace Research Institute, in 2003 the United States spent approximately 47% of the world's total military spending of US $956,000,000,000. In 2007 the United States spent over 50% of the world's total military expenditure, or more than all other nations combine.[citation needed] As a percentage of its GDP, the United States spends 3.7% on military, ranking it 26th in the world. This is higher by percent than France's 2.6%, and lower than Saudia Arabia's 10%[16]. This is historically fairly low for the United States. [17] Also, since it is an all-volunteer force and since most jobs within it require high degrees of technical skill and personnel retention, the United States armed forces have dramatically higher personnel costs, both military and civilian, compared to the militaries of countries which use conscription, many of which have far more troops than the United States. Six countries have more troops than the United States, five of them through conscription. Pay and benefits to U.S. servicemembers are significantly higher than to equal ranking military members of most other nations. Military BuildupTo meet the growing demands in the Middle East and around the world, Secretary of Defense Robert Gates proposed to the President to increase the overall size of the military by approximately 92,000 troops over the course of five years. Specifically, the proposal calls for an Army troop cap of 547,000 active duty soldiers and a troop cap of 202,000 active duty Marines. The total active duty force of the United States after the buildup will be about 1,479,000.[18] Notes and sources
