120-473: The Army Ballistic Missile Agency ( ABMA ) was formed to develop the U.S. Army's first large ballistic missile . The agency was established at Redstone Arsenal on 1 February 1956, and commanded by Major General John B. Medaris with Wernher von Braun as technical director. The Redstone missile was the first major project assigned to ABMA. The Redstone was a direct descendant of the V-2 missile developed by
240-614: A status quo antebellum. Two weeks after a treaty was signed (but not ratified), Andrew Jackson defeated the British in the Battle of New Orleans and siege of Fort St. Philip with an army dominated by militia and volunteers, and became a national hero. U.S. troops and sailors captured HMS Cyane , Levant and Penguin in the final engagements of the war. Per the treaty, both sides (the United States and Great Britain) returned to
360-651: A few months. The war remains the deadliest conflict in U.S. history, resulting in the deaths of 620,000 men on both sides. Based on 1860 census figures, 8% of all white males aged 13 to 43 died in the war, including 6.4% in the North and 18% in the South . Following the Civil War, the U.S. Army had the mission of containing western tribes of Native Americans on the Indian reservations . They set up many forts, and engaged in
480-534: A functional area. However, officers continue to wear the branch insignia of their former branch in most cases, as functional areas do not generally have discrete insignia. Some branches, such as Special Forces , operate similarly to functional areas in that individuals may not join their ranks until having served in another Army branch. Careers in the Army can extend into cross-functional areas for officers, warrant officers, enlisted, and civilian personnel. Before 1933,
600-590: A further expansion of the Jupiter-C intended for future space launches. It was a Juno I that launched the U.S.'s first satellite, Explorer 1 , on 1 February 1958 ( GMT ). ABMA's work on the Jupiter progressed throughout the U.S. Navy's brief involvement, especially work on the INS. The goal had originally been to match Redstone's accuracy at the Jupiter's much extended range, but as development continued it became clear
720-491: A limited war that did not include the use of strategic weapons on each other's cities. In that case, "if wars were to be kept limited, such weapons would have to be capable of hitting only tactical targets". This approach saw support of a number of influential theorists, notably Henry Kissinger , and was seized on as a uniquely Army mission. Although the Air Force had started their own IRBM to compete with Jupiter, development

Both the Regular Army and the Army Reserve are organized under Title 10 of the United States Code , while the National Guard is organized under Title 32 . While the Army National Guard is organized, trained, and equipped as a component of the U.S. Army, when it
960-487: A new Army Command (ACOM) in 2018. The Army Futures Command (AFC), is a peer of FORSCOM, TRADOC, and AMC, the other ACOMs. AFC's mission is modernization reform: to design hardware, as well as to work within the acquisition process which defines materiel for AMC. TRADOC's mission is to define the architecture and organization of the Army, and to train and supply soldiers to FORSCOM. AFC's cross-functional teams (CFTs) are Futures Command's vehicle for sustainable reform of
1080-480: A predominantly combat support role. The army converted to an all-volunteer force with greater emphasis on training to specific performance standards driven by the reforms of General William E. DePuy , the first commander of United States Army Training and Doctrine Command . Following the Camp David Accords that was signed by Egypt, Israel that was brokered by president Jimmy Carter in 1978, as part of
1200-618: A role in the invasions of Grenada in 1983 ( Operation Urgent Fury ) and Panama in 1989 ( Operation Just Cause ). By 1989 Germany was nearing reunification and the Cold War was coming to a close. Army leadership reacted by starting to plan for a reduction in strength. By November 1989 Pentagon briefers were laying out plans to reduce army end strength by 23%, from 750,000 to 580,000. A number of incentives such as early retirement were used. In 1990, Iraq invaded its smaller neighbor, Kuwait , and U.S. land forces quickly deployed to assure
1320-738: A strategy of seizing the coastline, blockading the ports, and taking control of the river systems. By 1863, the Confederacy was being strangled. Its eastern armies fought well, but the western armies were defeated one after another until the Union forces captured New Orleans in 1862 along with the Tennessee River. In the Vicksburg Campaign of 1862–1863, General Ulysses Grant seized the Mississippi River and cut off
SECTION 10
#17327733228101440-452: A strong need for one IRBM, let alone two. Through 1957 the situation between the Air Force and ABMA was almost nonfunctional, with ABMA requests for updates on the project going unanswered for months. The Air Force did, however, reduce the production rate from two missiles per month to one. They then began a review process with the thinly disguised goal of canceling Jupiter. When the Army was stripped of their long-range surface-to-surface role,
1560-449: A subscale version of the Jupiter reentry vehicle. The bare Jupiter-C flew for the first time on 20 September 1956, flying further and faster than any previous rocket. The complete system with a dummy reentry vehicle flew twice in 1957, the first on 15 May and the second on 8 August 1957. The second of these tests also used a new three-stage upper that had been designed for the Juno I rocket,
1680-471: A variety of V-2 -derived designs at the nearby White Sands Proving Ground . Around the same time, North American Aviation (NAA) won the contract to build a long-range cruise missile that became the SM-64 Navaho . This used ramjet power and needed to be boosted up to operational speed by a rocket. Their Propulsion Division was given two V-2 engines to work with to meet this requirement, along with
1800-634: A warhead weight of 3,100 kg (6,800 lb), range was reduced to only 282 km (175 mi). Design work was complete in 1952 and on 8 April 1952 it became known as the SSM-G-14 Redstone (Surface-to-Surface Missile, G for ground). The first ABMA-built prototype flew in August 1953, the first production-line model from Chrysler in July 1956, and the Redstone entered service in 1958. While
1920-664: A wealth of research papers from the original V-2 engine team. The NAA team discovered that a major upgrade to the V-2's original Model 39 engine was planned through the use of a new fuel injector design, but the Germans were not able to cure lingering combustion problems. Attacking this task, NAA successfully solved the problems and began using this new injector. This became the XLR-41 Phase III engine, which provided 330,000 N (74,000 lb f ) of thrust, one third greater than
2040-450: A wide variety of complaints between the two forces, on 18 November 1956, he published a memo that limited the Army to weapons with a range of 320 km (200 mi) or less, and those dedicated to air defense to half that. Jupiter's 2,400 km (1,500 mi) range was well over this limit, but instead of forcing them to cancel the project, Wilson had the ABMA team continue development and

As specified before the 2013 end-strength re-definitions, the three major types of brigade combat teams are: In addition, there are combat support and service support modular brigades. Combat support brigades include aviation (CAB) brigades, which will come in heavy and light varieties, fires (artillery) brigades (now transforms to division artillery) and expeditionary military intelligence brigades . Combat service support brigades include sustainment brigades and come in several varieties and serve

On 21 December 1965, the Trinity Site , selected in November 1944 for the Trinity nuclear test conducted on 16 July 1945 , was designated a National Historic Landmark district, and added to the National Register of Historic Places on 15 October 1966. The White Sands Test Center , headquartered at
2880-820: The American Revolutionary War (1775–1783). After the Revolutionary War, the Congress of the Confederation created the United States Army on 3 June 1784 to replace the disbanded Continental Army. The United States Army considers itself a continuation of the Continental Army, and thus considers its institutional inception to be the origin of that armed force in 1775. The U.S. Army is a uniformed service of
3000-656: The Army Ballistic Missile Agency , or ABMA. Taking the XLR-41, renamed as the NA-75-110 in U.S. Army use, they wrapped it in the largest airframe it could lift, increasing fuel load and extending the range. The result was essentially a larger version of the V-2. As tensions of the Cold War mounted, the Army changed the requirement to be able to carry smallest nuclear warheads in the inventory – with
3120-949: The Army Strategy 2018 articulated an eight-point addendum to the Army Vision for 2028. While the Army Mission remains constant, the Army Strategy builds upon the Army's Brigade Modernization by adding focus to corps and division -level echelons. The Army Futures Command oversees reforms geared toward conventional warfare . The Army's current reorganization plan is due to be completed by 2028. The Army's five core competencies are prompt and sustained land combat, combined arms operations (to include combined arms maneuver and wide–area security, armored and mechanized operations and airborne and air assault operations ), special operations forces , to set and sustain
3240-537: The Battle of 73 Easting were tank battles of historical significance. After Operation Desert Storm, the army did not see major combat operations for the remainder of the 1990s but did participate in a number of peacekeeping activities. In 1990 the Department of Defense issued guidance for "rebalancing" after a review of the Total Force Policy, but in 2004, USAF Air War College scholars concluded

During the Cold War, U.S. troops and their allies fought communist forces in Korea and Vietnam . The Korean War began in June 1950, when the Soviets walked out of a UN Security Council meeting, removing their possible veto. Under a United Nations umbrella, hundreds of thousands of U.S. troops fought to prevent
3480-585: The PGM-11 Redstone program continued, NAA was receiving a continual stream of orders from the U.S. Air Force to extend the range and payload of their Navaho design. This required a much larger missile, and a much larger booster to launch it. As a result, NAA was continually introducing new versions of their engines. By the mid-1950s, NAA had a version known as the XLR-43 running at 530,000 N (120,000 lb f ) thrust, while further reducing weight at

Later that same month, the initial report of the Killian Committee was published. Among its many recommendations was the statement that the U.S. should build an IRBM as soon as possible. They based their argument on the fact that an IRBM could strike any point in Europe from any point in Europe. It

During the 1960s, the Department of Defense continued to scrutinize the reserve forces and to question the number of divisions and brigades as well as the redundancy of maintaining two reserve components, the Army National Guard and the Army Reserve . In 1967, Secretary of Defense Robert McNamara decided that 15 combat divisions in
4200-489: The hydrogen peroxide system of the XLR-41 that powered the turbopumps and replaced it with a turbine that ran on the rocket fuel itself, simplifying the overall design. Von Braun's team initially considered making a version of the Redstone using the LR89 and adding a second stage, stretching the range to 1,900 km (1,200 mi). But ongoing work on the LR89 suggested that the engine could be further improved, and in 1954,
4320-611: The ABMA could have put a satellite into orbit at that time, had the U.S. government allowed ABMA to do so. A year later, the Soviets launched Sputnik 1 . When the Vanguard rocket failed, a Redstone-based Jupiter-C with an added fourth stage and thus designated as Juno I rocket, launched America's first satellite, Explorer 1 , on 1 February 1958 ( GMT ). Redstone was later used as a launch vehicle in Project Mercury . Redstone
4440-408: The ABMA team could improve on that considerably. This led to a period in which "The Army would lay down a particular accuracy, and wait for our arguments whether it was possible. We had to promise a lot, but were fortunate". This process ultimately delivered a design intended to provide 0.8 km (0.50 mi) accuracy at the full range, a radius one fourth that of the best INS designs being used by
4560-628: The ABMA's large booster program, headed by Wernher von Braun . Von Braun's Group was referred to as the "Working Group on Vehicular Program". In March 1958, ABMA was placed under the new U.S. Army Ordnance Missile Command (AOMC) along with Redstone Arsenal, the Jet Propulsion Laboratory , White Sands Proving Ground , and the Army Rocket and Guided Missile Agency (ARGMA). General Medaris was placed in command of AOMC and BG John A. Barclay took command of ABMA. On 1 July 1960,
4680-547: The AOMC space-related missions and most of its employees, facilities, and equipment were transferred to NASA , forming the George C. Marshall Space Flight Center (MSFC). Wernher von Braun was named MSFC director. BG Richard M. Hurst took command of ABMA from May 1960 until December 1961 when both ABMA and ARGMA were abolished and the remnants were folded directly into AOMC. In 1962, AOMC (the part that hadn't been transferred to NASA)
4800-461: The Air Force to ultimately deploy it. This was precisely the plan that Schriever had rejected the year before. The Army were apoplectic , and let the press know it. This ultimately led to the court-martial of Colonel John C. Nickerson Jr. , after he leaked information about various Army projects, including the then-secret Pershing missile . The Air Force were no happier, as they had little real interest in anything other than Atlas, and didn't see
4920-400: The Air Force took over those with greater range. The new design's 2,400 km (1,500 mi) range placed it within the umbrella of the Air Force, so the Army offered to design and build the missile for operation by the Air Force. In spite of addressing the calls for an Air Force M/IRBM, and that taking it over would keep the Army out of the long-range missile game, General Schriever dismissed

5040-515: The Air Force. The system was so accurate that a number of observers expressed their skepticism about the Army's goals, with the Weapons Systems Evaluation Group (WSEG) suggesting they were hopelessly optimistic. The Army's desire for accuracy was a side-effect of their mission concept for nuclear weapons. They saw the weapons as part of a large-scale battle in Europe, in which both sides would use nuclear weapons during

The U.S. Army is made up of three components: the active component, the Regular Army; and two reserve components, the Army National Guard and the Army Reserve. Both reserve components are primarily composed of part-time soldiers who train once
5280-472: The Army National Guard members were considered state militia until they were mobilized into the U.S. Army, typically at the onset of war. Since the 1933 amendment to the National Defense Act of 1916 , all Army National Guard soldiers have held dual status. They serve as National Guardsmen under the authority of the governor of their state or territory and as reserve members of the U.S. Army under
5400-411: The Army National Guard were unnecessary and cut the number to eight divisions (one mechanized infantry, two armored, and five infantry), but increased the number of brigades from seven to 18 (one airborne, one armored, two mechanized infantry and 14 infantry). The loss of the divisions did not sit well with the states. Their objections included the inadequate maneuver element mix for those that remained and
5520-409: The Army approached Rocketdyne to provide a similar design with a thrust of 600,000 N (130,000 lb f ). Over this period the weight of nuclear warheads was rapidly falling, and by combining this engine with a warhead of 910 kg (2,010 lb) they could build a single-stage missile able to reach 2,800 km (1,700 mi) while being significantly less complicated and easier to handle in
5640-473: The Army some sort of strategic role in the short term. The Air Force vision of war was significantly different from the Army's, consisting of a massive attack on the Soviet Union in the event of any sort of major military action, the so-called "Sunday punch". The possibility of a major war that did not escalate to the point where strategic weapons were used was a serious concern to Air Force planners. If
5760-570: The British were weakest to wear down their forces. Washington led victories against the British at Trenton and Princeton , but lost a series of battles in the New York and New Jersey campaign in 1776 and the Philadelphia campaign in 1777. With a decisive victory at Yorktown and the help of the French, the Continental Army prevailed against the British. After the war, the Continental Army
5880-461: The Canadian province of Upper Canada, British troops who had dubbed the U.S. Army "Regulars, by God!", were able to capture and burn Washington , which was defended by militia, in 1814. The regular army, however, proved they were professional and capable of defeating the British army during the invasions of Plattsburgh and Baltimore , prompting British agreement on the previously rejected terms of
6000-593: The Joint Coordinating Committee on Ballistic Missiles concluded that there were enough differences between the two concepts that an entirely new design should be built for the role. The Army, meanwhile, did not give up on their design. In September 1955, von Braun briefed the U.S. Secretary of Defense and the Armed Services Policy Council on long range missiles, pointing out that a 2,400 km (1,500 mi) missile
6120-523: The Jupiter missile was underway, design of the reentry vehicle was progressing rapidly. In order to gain test data on the design before the missile would be ready to launch it, ABMA designed the Jupiter-C , short for "Jupiter Composite Test Vehicle". This was not really a Jupiter at all, but a Redstone with an 2.4 m (7 ft 10 in) stretch to hold more fuel, topped with two upper stages consisting of clusters of small solid fuel rockets, topped by

#17327733228106240-584: The Missile Division retained the Navaho itself. With this breakup of duties, both Rocketdyne and Autonetics were soon asked to provide solutions for other projects. In particular, the Air Force asked Rocketdyne to provide an engine for their SM-65 Atlas which they did by adapting the XLR-43 to run on JP-4 instead of alcohol , becoming the LR89 . In addition to the switch to JP-4, the engine did away with
6360-407: The Model 39, and was lighter and smaller than the German design. The outbreak of the Korean War in June 1950 led to calls for the rapid deployment of new missiles, and the U.S. Army responded by developing a requirement for a ballistic missile with 800 km (500 mi) range while carrying a 230 kg (510 lb) warhead that could be operational as rapidly as possible. The fastest solution
6480-545: The National Guard, while all states maintain regulations for state militias . State militias are both "organized", meaning that they are armed forces usually part of the state defense forces, or "unorganized" simply meaning that all able-bodied males may be eligible to be called into military service. The U.S. Army is also divided into several branches and functional areas . Branches include officers, warrant officers, and enlisted Soldiers while functional areas consist of officers who are reclassified from their former branch into

The Army of the United States was re-established for the Korean War and Vietnam War and was demobilized upon the suspension of the draft . Currently, the Army is divided into the Regular Army , the Army Reserve, and the Army National Guard . Some states further maintain state defense forces , as a type of reserve to
6720-458: The Revolutionary War progressed, French aid, resources, and military thinking helped shape the new army. A number of European soldiers came on their own to help, such as Friedrich Wilhelm von Steuben , who taught Prussian Army tactics and organizational skills. The Army fought numerous pitched battles, and sometimes used Fabian strategy and hit-and-run tactics in the South in 1780 and 1781; under Major General Nathanael Greene , it hit where

The 2015 expenditure for Army research, development and acquisition changed from $ 32 billion projected in 2012 for FY15 to $ 21 billion for FY15 expected in 2014. By 2017, a task force was formed to address Army modernization, which triggered shifts of units: CCDC , and ARCIC , from within Army Materiel Command (AMC), and Army Training and Doctrine Command (TRADOC), respectively, to
8640-439: The end to the practice of rotating divisional commands among the states that supported them. Under the proposal, the remaining division commanders were to reside in the state of the division base. However, no reduction in total Army National Guard strength was to take place, which convinced the governors to accept the plan. The states reorganized their forces accordingly between 1 December 1967 and 1 May 1968. The Total Force Policy
8760-458: The existing Juno series, using various combinations of parts from Army and Air Force missiles to meet a wide variety of performance goals. During a visit by Advanced Research Projects Agency (ARPA), the various plans were presented, notably the Juno V concept which ABMA saw as a solution for launching the spy satellites the Air Force was designing. The Air Force was, unsurprisingly, planning to use its own launcher for this, an expanded version of
8880-468: The field than a two-stage model. This engine was continually upgraded, ultimately reaching 670,000 N (150,000 lb f ). This last model, known to the Army as the NAA-150-200, became much better known by its Rocketdyne model number, S-3. In January 1955, the Air Force's Scientific Advisory Group (SAG) urged the Air Force to develop a medium-range ballistic missile (MRBM). They felt that it
9000-577: The first range commander, Colonel Harold Turner (1945–1947), in 1980. A recreational shooting range just inside the "El Paso gate" on the south is outside of the Post Area. The 1972 DoD Centers for Countermeasures (CCM) evaluates precision guided munitions and other devices in electronic counter- and counter-countermeasures environments. Other operations on WSMR land include the Launch Abort Flight Test Complex for
9120-580: The following years, the mission changed from conflict between regular militaries to counterinsurgency , resulting in the deaths of more than 4,000 U.S. service members (as of March 2008) and injuries to thousands more. 23,813 insurgents were killed in Iraq between 2003 and 2011. Until 2009, the army's chief modernization plan, its most ambitious since World War II, was the Future Combat Systems program. In 2009, many systems were canceled, and
9240-587: The forces that landed in French North Africa and took Tunisia and then moved on to Sicily and later fought in Italy . In the June 1944 landings in northern France and in the subsequent liberation of Europe and defeat of Nazi Germany , millions of U.S. Army troops played a central role. In 1947, the number of soldiers in the US Army had decreased from eight million in 1945 to 684,000 soldiers and
9360-420: The full range of military operations and the spectrum of conflict, in support of combatant commanders ". The branch participates in conflicts worldwide and is the major ground-based offensive and defensive force of the United States of America. The United States Army serves as the land-based branch of the U.S. Armed Forces . Section 7062 of Title 10, U.S. Code defines the purpose of the army as: In 2018,
9480-685: The geographical status quo. Both navies kept the warships they had seized during the conflict. The army's major campaign against the Indians was fought in Florida against Seminoles . It took long wars (1818–1858) to finally defeat the Seminoles and move them to Oklahoma. The usual strategy in Indian wars was to seize control of the Indians' winter food supply, but that was no use in Florida where there
9600-471: The guidance would reverse the Total Force Policy which is an "essential ingredient to the successful application of military force". On 11 September 2001, 53 Army civilians (47 employees and six contractors) and 22 soldiers were among the 125 victims killed in the Pentagon in a terrorist attack when American Airlines Flight 77 commandeered by five Al-Qaeda hijackers slammed into the western side of
9720-575: The idea outright: It would be naive to think that the Army would develop a weapon and then turn it over to the Air Force for operation. Therefore, I strongly recommend that our relationship with Redstone [Arsenal] remain on an exchange of information basis. As the calls for an IRBM continued, Schriever finally acquiesced and suggested that an IRBM could be created out of a down-scaled Atlas, thereby avoiding any duplication of effort. Contract tenders for such designs were sent out in May 1955. However, by July 1955,
9840-771: The last of the American Indian Wars . U.S. Army troops also occupied several Southern states during the Reconstruction Era to protect freedmen . The key battles of the Spanish–American War of 1898 were fought by the Navy. Using mostly new volunteers , the U.S. forces defeated Spain in land campaigns in Cuba and played the central role in the Philippine–American War . Starting in 1910,
9960-434: The middle of 1956, both forces were engaged in tit-for-tat attacks in the press, with the Air Force calling the Army "unfit to guard the nation" on the front page of The New York Times and sending out press releases about how bad their SAM-A-25 Nike Hercules missile was compared to the Air Force's IM-99 Bomarc . Tired of the internecine fighting, Secretary of Defense Wilson decided to end it once and for all. Examining
10080-545: The protection of Saudi Arabia . In January 1991 Operation Desert Storm commenced, a U.S.-led coalition which deployed over 500,000 troops, the bulk of them from U.S. Army formations, to drive out Iraqi forces . The campaign ended in total victory, as Western coalition forces routed the Iraqi Army . Some of the largest tank battles in history were fought during the Gulf war. The Battle of Medina Ridge , Battle of Norfolk and
10200-458: The question arose as to what to do with the ABMA team. The large team built up for the Redstone and Jupiter efforts would not be needed for the short range missiles fitting the Wilson range limits, but breaking up the team was something no one wanted. The team soon began working on non-military rockets, which did not fall under the Wilson range requirements. This led to a series of designs extending
10320-698: The remaining were swept into the BCT modernization program . By 2017, the Brigade Modernization project was completed and its headquarters, the Brigade Modernization Command, was renamed the Joint Modernization Command, or JMC. In response to Budget sequestration in 2013 , Army plans were to shrink to 1940 levels, although actual Active-Army end-strengths were projected to fall to some 450,000 troops by
10440-490: The same time. Much of this was due to the introduction of the tubular wall combustion chamber, which was much lighter than the cast-steel designs of the V-2, while also offering much better cooling which allowed the combustion rate, and thus thrust, to be increased. While the Navajo program dragged on, NAA split the team into three groups, Rocketdyne handled engines, Autonetics developed inertial navigation systems (INS) and
10560-605: The service chiefs from each of the four military services belonging to the Department of Defense who advise the president of the United States , the secretary of defense and the National Security Council on operational military matters, under the guidance of the chairman and vice chairman of the Joint Chiefs of Staff . In 1986, the Goldwater–Nichols Act mandated that operational control of
10680-489: The service of the army. By the twentieth century, the U.S. Army had mobilized the U.S. Volunteers on four occasions during each of the major wars of the nineteenth century. During World War I, the " National Army " was organized to fight the conflict, replacing the concept of U.S. Volunteers. It was demobilized at the end of World War I and was replaced by the Regular Army, the Organized Reserve Corps, and
10800-456: The services follows a chain of command from the president to the secretary of defense directly to the unified combatant commanders , who have control of all armed forces units in their geographic or function area of responsibility, thus the secretaries of the military departments (and their respective service chiefs underneath them) only have the responsibility to organize, train and equip their service components. The army provides trained forces to
10920-477: The side of Britain , France , Russia , Italy and the other Allies . U.S. troops were sent to the Western Front and were involved in the last offensives that ended the war. With the armistice in November 1918, the army once again decreased its forces. In 1939, estimates of the Army's strength ranged between 174,000 and 200,000 soldiers, smaller than that of Portugal 's, which ranked it 17th or 19th in
11040-457: The southern part of the range in a west-northeast direction and is subject to periodic road closures during test firings at the range. U.S. Highway 380 runs east-west along the northern edge of WSMR between San Antonio and Carrizozo , and is also subject to periodic closures during test firings. New Mexico State Road 525 provides access from U.S. Highway 380 to the north end of WSMR near Stallion Army Airfield . El Paso International Airport
11160-476: The standard support role in an army. The U.S. Army's conventional combat capability currently consists of 11 active divisions and 1 deployable division headquarters (7th Infantry Division) as well as several independent maneuver units. White Sands Missile Range White Sands Missile Range ( WSMR ) is a United States Army military testing area and firing range located in the US state of New Mexico . The range
11280-443: The state militias. In the 1920s and 1930s, the "career" soldiers were known as the " Regular Army " with the "Enlisted Reserve Corps" and "Officer Reserve Corps" augmented to fill vacancies when needed. In 1941, the " Army of the United States " was founded to fight World War II. The Regular Army, Army of the United States, the National Guard, and Officer/Enlisted Reserve Corps (ORC and ERC) existed simultaneously. After World War II,
11400-545: The states of California , Nevada , Utah , Colorado , Arizona , Wyoming and New Mexico . The American Civil War was the costliest war for the U.S. in terms of casualties. After most slave states , located in the southern U.S., formed the Confederate States , the Confederate States Army , led by former U.S. Army officers, mobilized a large fraction of Southern white manpower. Forces of
11520-472: The statutory authority to conduct all the affairs of the army under the authority, direction, and control of the secretary of defense . The chief of staff of the Army , who is the highest-ranked military officer in the army, serves as the principal military adviser and executive agent for the secretary of the Army, i.e., its service chief; and as a member of the Joint Chiefs of Staff , a body composed of
11640-543: The takeover of South Korea by North Korea and later to invade the northern nation. After repeated advances and retreats by both sides and the Chinese People's Volunteer Army 's entry into the war, the Korean Armistice Agreement returned the peninsula to the status quo in July 1953. The Vietnam War is often regarded as a low point for the U.S. Army due to the use of drafted personnel ,
11760-603: The theater for the joint force, and to integrate national, multinational, and joint power on land. The Continental Army was created on 14 June 1775 by the Second Continental Congress as a unified army for the colonies to fight Great Britain , with George Washington appointed as its commander. The army was initially led by men who had served in the British Army or colonial militias and who brought much of British military heritage with them. As
11880-669: The total number of active divisions had dropped from 89 to 12. The leaders of the Army saw this demobilization as a success. In the Pacific War , U.S. Army soldiers participated alongside the United States Marine Corps in capturing the Pacific Islands from Japanese control. Following the Axis surrenders in May (Germany) and August (Japan) of 1945, army troops were deployed to Japan and Germany to occupy
12000-1097: The two defeated nations. Two years after World War II, the Army Air Forces separated from the army to become the United States Air Force in September 1947. In 1948, the army was desegregated by order 9981 of President Harry S. Truman . The end of World War II set the stage for the East–West confrontation known as the Cold War . With the outbreak of the Korean War , concerns over the defense of Western Europe rose. Two corps, V and VII , were reactivated under Seventh United States Army in 1950 and U.S. strength in Europe rose from one division to four. Hundreds of thousands of U.S. troops remained stationed in West Germany, with others in Belgium ,
12120-620: The unpopularity of the war with the U.S. public and frustrating restrictions placed on the military by U.S. political leaders. While U.S. forces had been stationed in South Vietnam since 1959, in intelligence and advising/training roles, they were not deployed in large numbers until 1965, after the Gulf of Tonkin Incident . U.S. forces effectively established and maintained control of the "traditional" battlefield, but they struggled to counter
12240-493: The upcoming Titan II . ARPA then provided ABMA with initial funding to keep the Juno V project moving, and assigned it von Braun's preferred name of " Saturn ", meaning "the one after Jupiter". Meanwhile, President Eisenhower was interested in handing the job of space exploration to a civilian body, which would avoid any potential issues over the militarization of space. This was formed as NASA in late 1958. Some months later ABMA
12360-600: The von Braun team in Germany during World War II . After the Naval Research Laboratory 's Project Vanguard was chosen by the DoD Committee on Special Capabilities , over the ABMA's proposal to use a modified Redstone ballistic missile as a satellite launch vehicle, ABMA was ordered to stop work on launchers for satellites and focus, instead, on military missiles. Von Braun continued work on
12480-583: The world in size. General George C. Marshall became Army chief of staff in September 1939 and set about expanding and modernizing the Army in preparation for war. The United States joined World War II in December 1941 after the Japanese attack on Pearl Harbor . Some 11 million Americans were to serve in various Army operations. On the European front , U.S. Army troops formed a significant portion of
12600-632: Was lackadaisical . They had the much more impressive Atlas to worry about, and even that saw relatively little interest in a force dominated by Strategic Air Command 's bomber-centric strategic vision. Curtis LeMay , leader of SAC, was generally uninterested in Atlas, considering it useful only as a way to blast holes in the Soviet defensive systems to let his bombers through. But as the Jupiter program began to progress they became increasingly concerned that it would enter service before Atlas, potentially handing
12720-426: Was a logical extension of the Redstone. He proposed a six-year development program costing US$ 240 million (equivalent to $ 2.73 billion in 2023) with a total production of 50 prototype missiles. To test various parts of the Jupiter equipment, ABMA began launching Jupiter hardware on previously planned Redstone development missions. These were known under the name Jupiter-A. Among the systems tested by Jupiter-A were
12840-583: Was adopted by Chief of Staff of the Army General Creighton Abrams in the aftermath of the Vietnam War and involved treating the three components of the army – the Regular Army , the Army National Guard and the Army Reserve as a single force. General Abrams' intertwining of the three components of the army effectively made extended operations impossible without the involvement of both the Army National Guard and Army Reserve in
12960-587: Was also deployed by the U.S. Army as the PGM-11, the first missile to carry a nuclear warhead. Studies began in 1956 for a replacement for the Redstone missile. Initially called the Redstone-S (S for solid), the name was changed to MGM-31 Pershing and a contract was awarded to The Martin Company , beginning a program that lasted 34 years. In early 1958, NACA 's " Stever Committee " included consultation from
13080-876: Was at first very small and after General St. Clair's defeat at the Battle of the Wabash, where more than 800 soldiers were killed, the Regular Army was reorganized as the Legion of the United States , established in 1791 and renamed the United States Army in 1796. In 1798, during the Quasi-War with France, the U.S. Congress established a three-year " Provisional Army " of 10,000 men, consisting of twelve regiments of infantry and six troops of light dragoons . In March 1799, Congress created an "Eventual Army" of 30,000 men, including three regiments of cavalry . Both "armies" existed only on paper, but equipment for 3,000 men and horses
13200-438: Was believed that this type of weapon would be highly desirable to the Soviets and thus since they were very likely to develop such a system, the U.S. should build one first. In March 1955, the Army approached the Air Force about their MRBM design. When the Air Force had split from the Army in 1947, the two forces had a tacit agreement that the Army would be responsible for designs flying less than 1,600 km (990 mi), while
13320-501: Was even official. The Air Force states the first was on 14 March 1956. Likewise the Air Force does not claim the last three Redstone flights, RS-46, CC-43 and CC-48, to be part of the Jupiter-A program, while ABMA lists them. In total, ABMA lists 25 launches as part of the Jupiter-A series, every Redstone launched between September 1955 and 11 June 1958. The Air Force lists only the 20 in the middle of this period. While development of
13440-544: Was far less technically risky than the SM-65 Atlas ICBM the Air Force was developing, and would enter service earlier. General Bernard Schriever , leader of the U.S. Air Force's Western Development Division in charge of Atlas development, was opposed to the concept, feeling that it would divert resources from the Atlas efforts. In February 1955, the United Kingdom expressed an interest in obtaining an intermediate-range ballistic missile (IRBM) that could strike
13560-679: Was handed over to NASA to become the Marshall Space Flight Center . When the next president, John F. Kennedy , announced the goal of landing on the Moon on 25 May 1961, two competing designs were considered for the booster, Marshall's Saturn V and the NASA Nova . The subsequent selection of the smaller Saturn was a factor in the success of the Apollo project . United States Army The United States Army ( USA )
13680-498: Was no winter. The second strategy was to form alliances with other Indian tribes, but that too was useless because the Seminoles had destroyed all the other Indians when they entered Florida in the late eighteenth century. The U.S. Army fought and won the Mexican–American War (1846–1848), which was a defining event for both countries. The U.S. victory resulted in acquisition of territory that eventually became all or parts of
13800-674: Was originally established in 1941 as the Alamogordo Bombing and Gunnery Range , where the Trinity test site lay at the northern end of the Range, in Socorro County near the towns of Carrizozo and San Antonio . It then became the White Sands Proving Ground on 9 July 1945. White Sands National Park founded in the 1930s is located within the range. As the largest military installation in
13920-590: Was procured and stored. The War of 1812 , the second and last war between the United States and Great Britain, had mixed results. The U.S. Army did not conquer Canada but it did destroy Native American resistance to expansion in the Old Northwest and stopped two major British invasions in 1814 and 1815. After taking control of Lake Erie in 1813, the U.S. Army seized parts of western Upper Canada, burned York and defeated Tecumseh , which caused his Western Confederacy to collapse. Following U.S. victories in
14040-495: Was purely strategic. They may also have been motivated by the WSEG's comments that if the Jupiter team's accuracy claims were true, "they would indicate that Jupiter is the most promising weapon for development". As the Air Force's arguments against Jupiter grew more vocal, the argument came to encompass several other ongoing projects that the two forces had in common, including surface-to-air missiles and anti-ballistic missiles . By
14160-505: Was quickly given land certificates and disbanded in a reflection of the republican distrust of standing armies. State militias became the new nation's sole ground army, except a regiment to guard the Western Frontier and one battery of artillery guarding West Point 's arsenal. However, because of continuing conflict with Native Americans , it was soon considered necessary to field a trained standing army. The Regular Army
14280-469: Was restructured into the new U.S. Army Missile Command (MICOM). In the aftermath of World War II , a number of German rocket scientists and engineers were moved to the United States as part of Operation Paperclip . Rocketry was at that time considered to be a sort of long-range artillery, and naturally fell to the Army to explore. The group was settled at Fort Bliss , Texas – where they aided General Electric 's Project Hermes efforts to build and test
14400-801: Was to provide the German team with anything they needed to achieve this goal by adapting the V-2 design. The team, under the leadership of Wernher von Braun , began work on the problem at Fort Bliss. In 1951, they moved to the Redstone Arsenal in Huntsville, Alabama , home to the Army's Ordnance commands. Initially known as the Ordnance Guided Missile Center, then the Guided Missile Development Division (GMDD), in 1956 they finally became
