The formation of
11692-794: The Vehicle Propulsion Directorate and the Vehicle Structures Directorate. SEN and PSD were merged to form the Sensors and Electron Devices Directorate (SEDD), and ASHPC became the Corporate Information and Computing Center (CICC). By 1997, ARL managed only five technical directorates (WMRD, IST, SEDD, HRED, and SLAD) and two centers (VTC and CICC). In 1998, ARL officially incorporated the Army Research Office (ARO) into its organization. Until this point, ARO had existed separately from
11840-423: The acquisition process for the future. In order to support the Army's modernization priorities, its FY2020 budget allocated $ 30 billion for the top six modernization priorities over the next five years. The $ 30 billion came from $ 8 billion in cost avoidance and $ 22 billion in terminations. The task of organizing the U.S. Army commenced in 1775. In the first one hundred years of its existence,
11988-764: The activities of three existing university centers of excellence: the Army High Performance Computing Research Center at the University of Minnesota , the Information Sciences Center at Clark Atlanta University , and the Institute for Advanced Technology at the University of Texas at Austin . ARL eventually discontinued the FedLab model in 2001 and adopted Collaborative Technology Alliances (CTAs) and Collaborative Research Alliances (CRAs) as successors to
12136-491: The agreement, both the United States and Egypt agreed that there would be a joint military training led by both countries that would usually take place every 2 years, that exercise is known as Exercise Bright Star . The 1980s was mostly a decade of reorganization. The Goldwater-Nichols Act of 1986 created unified combatant commands bringing the army together with the other four military services under unified, geographically organized command structures. The army also played
12284-650: The army began acquiring fixed-wing aircraft . In 1910, during the Mexican Revolution , the army was deployed to U.S. towns near the border to ensure the safety of lives and property. In 1916, Pancho Villa , a major rebel leader, attacked Columbus, New Mexico , prompting a U.S. intervention in Mexico until 7 February 1917. They fought the rebels and the Mexican federal troops until 1918. The United States joined World War I as an "Associated Power" in 1917 on
12432-619: The authority of the president, in the Army National Guard of the United States. Since the adoption of the total force policy, in the aftermath of the Vietnam War, reserve component soldiers have taken a more active role in U.S. military operations. For example, Reserve and Guard units took part in the Gulf War , peacekeeping in Kosovo , Afghanistan, and the 2003 invasion of Iraq . [REDACTED] Headquarters, United States Department of
12580-662: The building, as part of the September 11 attacks . In response to the 11 September attacks and as part of the Global War on Terror , U.S. and NATO forces invaded Afghanistan in October 2001, displacing the Taliban government. The U.S. Army also led the combined U.S. and allied invasion of Iraq in 2003; it served as the primary source for ground forces with its ability to sustain short and long-term deployment operations. In
12728-658: The changes in the organization's acquisition and readiness practices. In January 1978, the U.S. Army discontinued ECOM and formally activated three major subordinate commands under DARCOM: the Communications and Electronics Materiel Readiness Command (CERCOM), the Communications Research and Development Command (CORADCOM), and the Electronics Research and Development Command (ERADCOM). As the sole major subordinate command responsible for
12876-466: The combatant commanders for use as directed by the secretary of defense. By 2013, the army shifted to six geographical commands that align with the six geographical unified combatant commands (CCMD): The army also transformed its base unit from divisions to brigades . Division lineage will be retained, but the divisional headquarters will be able to command any brigade, not just brigades that carry their divisional lineage. The central part of this plan
13024-488: The creation of numerous research facilities by the U.S. Army to ensure that the country remained competitive on the international stage, especially as Cold War tensions reached new heights. The high demand for greater and more sophisticated military capabilities led to a proliferation of Army laboratories that not only advanced competing military interests but also operated in an independent fashion with minimal supervisory control or coordination from U.S. Army headquarters. By
13172-468: The early 1960s, the Army recognized a significant flaw in this approach to pursuing in-house research and development. Competition for government funding led to fierce rivalries between the research facilities that ultimately eroded communication between the Army laboratories. Research installations began to prioritize the survival and longevity of their own operations over the overarching Army goals and engaged in turf disputes to protect their own interests. As
13320-431: The eighth element placed in LABCOM, retained its original functions of managing grants and contracts with individual scientists, academia, and nonprofit entities to promote basic research relevant to the U.S. Army. Despite the significant changes made to the structure of the command, none of the dispersed research facilities were physically relocated for the formation of LABCOM. Although centralized oversight addressed some of
13468-631: The end of FY2017. From 2016 to 2017, the Army retired hundreds of OH-58 Kiowa Warrior observation helicopters, while retaining its Apache gunships. 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
13616-439: 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
13764-580: 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
13912-587: 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
14060-570: The former Ordnance Corps facilities became known as AMC laboratories and reported directly to AMC headquarters, the former Signal Corps facilities reported to a major subordinate command in AMC called the Electronics Command (ECOM). Although AMC had hoped that this arrangement would encourage research sharing and foster cooperation, the lack of progress on this issue prompted the U.S. Army to change its approach. In December 1973, Secretary of
14208-420: 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,
14356-685: 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
14504-471: 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
14652-574: The identity of the centralized laboratory began to take shape. Although the proposed centralized laboratory was originally referred to as the Combat Materiel Research Laboratory in the LAB-21 Study, the name was ultimately changed to the Army Research Laboratory. In addition, the Army decided to have a civilian director occupy the top management position with a general officer as deputy, as opposed to
14800-575: The laboratory's final extended campus location. On July 1, 2018, the Army formally established the U.S. Army Futures Command (AFC) as the Army's fourth major command alongside the U.S. Army Materiel Command , the U.S. Army Training and Doctrine Command , and the U.S. Army Forces Command . The reorganization came in response to criticisms from Secretary of the Army Mark Esper regarding the slow speed of Army technology development, testing, and fielding. The formation of AFC served to consolidate
14948-592: The laboratory's intramural research and manages DEVCOM ARL's flagship research efforts. ARO executes the laboratory's extramural research programs in scientific disciplines tied to the laboratory's research competencies. ARO administers funding for Army-relevant research conducted at universities and businesses across the United States. Located at Research Triangle Park in North Carolina, ARO engages in partnerships with members of academia and industry to promote high-risk yet high-payoff research in an effort to address
15096-475: The lack of unity among the laboratories. General Richard H. Thompson , the new Commanding General of AMC, proposed an initiative to consolidate and centralize the management of all the AMC laboratories under a single major subordinate command. This concept of a Laboratory Command was quickly adopted by the Army despite receiving unfavorable reviews that cited the likelihood of increased bureaucratic layering and overhead expenses. In July 1985, AMC officially activated
15244-771: 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,
15392-501: The management of installations, as well as maintenance and parts distribution. It was established on 8 May 1962 and was activated on 1 August of that year as a major field command of the U.S. Army. Lieutenant General Frank S. Besson, Jr. , who directed the implementation of the Department of Army study that recommended creation of a "materiel development and logistics command", served as its first commander. AMC operates depots; arsenals; ammunition plants; and other facilities, and maintains
15540-416: The management problems that the Army sought to resolve, the geographic separation between the laboratories considerably hindered LABCOM's research synergy. To the Army's dismay, competition among the laboratories and duplicated research persisted. The idea behind a centralized Army laboratory for basic research emerged in response to U.S. military downsizing following the end of the Cold War. In December 1988,
15688-399: The money, time, and manpower to help the U.S. Army catch up to the rapid pace at which commercial wireless devices were evolving, much less incorporate the newest advancements into military applications. The Army determined that the solution was to join ARL's in-house capabilities with those of commercial businesses and university laboratories. This decision led to the transformation of ARL into
15836-486: The newest regional site in Aberdeen Proving Ground, Maryland, has technical focus areas in high-performance computing, autonomous systems, human-agent teaming, cybersecurity, materials and manufacturing, power and energy, extreme materials, and quantum systems. A University Affiliated Research Center (UARC) is a university-led collaboration among universities, industry, and Army laboratories that serve to strengthen and maintain technological capabilities that are important to
15984-407: The operation of the laboratories. Based on their guidance, implementation of the laboratory consolidation plan was delayed to January 1992. The Federal Advisory Commission also communicated that, in order to address the laboratories’ deep-rooted competition problem, the centralized laboratory should be free from financial pressure and should not have to compete for research funds. As planning continued,
16132-496: The original plan of having a major general serve as a military commander alongside a civilian technical director. In accordance with the requirements established by BRAC 91, the Army discontinued LABCOM and provisionally established the U.S. Army Research Laboratory on July 23, 1992. The seven LABCOM laboratories were subsequently consolidated to form ARL's 10 technical directorates: the Electronics and Power Sources Directorate;
16280-513: The other former LABCOM elements. As a part of this change, ARO's director became the ARL deputy director for basic research. Following Lyons’ retirement in September 1998, Robert Whalin, the former director of the U.S. Army Corps of Engineers Waterways Experiment Station , was assigned as ARL's second director in December 1998. Shortly thereafter, the Corporate Information and Computing Center
16428-484: The process behind how the Army developed technology for its troops. Believing that AMC did not deliver its products to the desired recipients quickly enough, Kern directed the unification of all of AMC's laboratories and RDECs under one command in order to foster synergy. In October 2002, he created the U.S. Army Research, Development and Engineering Command (RDECOM) to consolidate these research facilities under one command structure. The Army officially established RDECOM as
16576-478: The projected end strength for the Regular Army (USA) was 480,893 soldiers; the Army National Guard (ARNG) had 336,129 soldiers and the U.S. Army Reserve (USAR) had 188,703 soldiers; the combined-component strength of the U.S. Army was 1,005,725 soldiers. As a branch of the armed forces, the mission of the U.S. Army is "to fight and win our Nation's wars, by providing prompt, sustained land dominance, across
16724-545: 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
16872-557: The purposes of developing partnerships and fostering interest in Army-relevant research. The first regional site, ARL West, was established in Playa Vista, California , on April 13, 2016. Its placement at the University of Southern California ’s Institute for Creative Technologies reflected the laboratory's goals to collaborate with organizations located in and around the Los Angeles region. The second regional site, ARL South,
17020-491: The reconfiguration of ARL as an open laboratory in order to increase the number of staff exchanges. These changes, which made ARL resemble NIST, were endorsed by AMC Commander General Jimmy D. Ross in December 1993. Around the same time, the Under Secretary of Defense chartered a task force on defense laboratory management, which recommended a change in approach to ARL's operations in 1994. This recommendation came as
17168-698: 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
17316-563: The research facilities contributed to a lack of responsiveness in addressing the Army's modern, mission-oriented needs. The advisory committee recommended separating the development of communications and automatic data processing from the development of electronic warfare capabilities. Following the guidance given by AMARC, AMC redesignated itself as the Material Development and Readiness Command (DARCOM) in January 1976 to reflect
17464-605: 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
17612-489: 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
17760-456: 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
17908-533: 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
18056-424: 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. United States Army Materiel Command The U.S. Army Materiel Command ( AMC ) is the primary provider of materiel to the United States Army . The Command's mission includes
18204-443: 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,
18352-545: 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
18500-412: 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
18648-543: 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 ,
18796-948: The termination of the FedLabs model in 2001, DEVCOM ARL continued to collaborate with private industry and academia through Collaborative Technology Alliances (CTAs) and Collaborative Research Alliances (CRAs). CTAs represent partnerships that focus on the rapid transition of new innovations and technologies found in academia to the U.S. manufacturing base through cooperation with private industry. CRAs represent partnerships that seek to further develop innovative science and technology in academia that pertains to Army interests. The laboratory also engaged in International Technology Alliances (ITAs) that facilitate collaborations for research and development with foreign government entities alongside academia and private industry. Located at White Sands Missile Range in New Mexico,
18944-603: 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
19092-718: 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
19240-465: The transition of existing LABCOM research and development activities into a new environment. Despite the relocation of Army personnel from different research facilities across the country, ARL's first year of operation witnessed the continuation of ongoing LABCOM research without significant setbacks. Lines of effort conducted by ARL that year included the Warrior's Edge virtual reality simulation program,
19388-1148: 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 ,
19536-558: The two major subordinate commands to create the Communications-Electronics Command (CECOM). Not long after DARCOM carried out its reorganization, however, the Army launched another review that scrutinized its structure, indicating that the changes failed to resolve the existing issues. DARCOM later changed its name back to AMC in August 1984. In 1984, the U.S. Army initiated a different strategy to address
19684-452: 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
19832-433: The vulnerability of Army weapons and electronic communication systems to hostile electronic warfare as well as coordinating missile electronic countermeasure efforts for the U.S. Army. 39°01′47″N 76°57′53″W / 39.0296°N 76.9647°W / 39.0296; -76.9647 United States Army The United States Army ( USA ) is the land service branch of the United States Armed Forces . It
19980-417: 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
20128-427: Was a research facility under the U.S. Army Materiel Command that specialized in metallurgy and materials science and engineering for ordnance and other military purposes. Located in Watertown, Massachusetts , MTL was originally known as the Watertown Arsenal Laboratories and represented one of many laboratory buildings erected at Watertown Arsenal. WAL was renamed the Army Materials Research Agency (AMRA) in 1962 and then
20276-439: 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
20424-527: Was also appended in front of the names of the eight research facilities assigned to the new major subordinate command: CCDC Armaments Center , CCDC Aviation & Missile Center , CCDC Army Research Laboratory, CCDC Chemical Biological Center , CCDC C5ISR , CCDC Data & Analysis Center, CCDC Ground Vehicle Systems Center , and CCDC Soldier Center . In 2020, CCDC changed its abbreviation to DEVCOM, resulting in CCDC ARL becoming DEVCOM ARL. In 2022, DEVCOM ARL discontinued its technical directorates and adopted
20572-426: Was also transitioned into the Survivability/Lethality Analysis Directorate (SLAD). In 1996, ARL underwent further restructuring in response to calls by the U.S. Army to decrease the number of directorates. The laboratory formed the Weapons and Materials Research Directorate (WMRD) by combining the Weapons Technology Directorate and the Materials Directorate. It also created the Vehicle Technology Center (VTC) by combining
20720-662: 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
20868-404: Was established in Austin, Texas , on November 16, 2016. Its placement at the University of Texas at Austin ’s J.J. Pickle Research Center reflected the laboratory's goals to partner with organizations in Texas as well as surrounding areas in New Mexico , Louisiana , and Oklahoma . The third regional site, ARL Central, was established in Chicago, Illinois , on November 10, 2017. Its placement at
21016-412: Was established in 1992 to unify the activities of the seven corporate laboratories of the U.S. Army Laboratory Command (LABCOM) as well as consolidate other Army research elements to form a centralized laboratory. The seven corporate laboratories that merged were the Atmospheric Sciences Laboratory (ASL), the Ballistic Research Laboratory (BRL), the Electronics Technology and Devices Laboratory (ETDL),
21164-410: Was established, the term “laboratories” became reserved exclusively for the research facilities under LABCOM. The research facilities that did not transfer to LABCOM became known as Research, Development, and Engineering Centers (RDECs). This naming distinction highlighted a major shift in the roles that both groups adopted. As part of the change, the laboratories took charge of AMC's basic research, while
21312-606: Was most notably known for its work on the proximity fuze . The Human Engineering Laboratory was a research facility under the U.S. Army Materiel Command that specialized in human performance research, human factors engineering , robotics, and human-in-the-loop technology. Located at Aberdeen Proving Ground, HEL acted as the Army's lead laboratory for human factors and ergonomics research from 1951 to 1992. Researchers at HEL investigated methods to maximize combat effectiveness, improve weapons and equipment designs, and reduce operation costs and errors. The Materials Technology Laboratory
21460-436: 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
21608-528: 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
21756-439: 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
21904-404: Was renamed to the Corporate Information and Computing Directorate, and the Vehicle Technology Center was renamed to the Vehicle Technology Directorate. In May 2000, ARL combined the Information Science and Technology Directorate and the Corporate Information and Computing Directorate to form the Computational and Information Sciences Directorate (CISD). With this change, ARL administered, in total,
