Code, Title 10, Subtitle B, Chapter 301, Section 3001. As the oldest and most senior branch of the U.S. military in order of precedence,[9] the modern U.S. Army
Army
has its roots in the Continental Army, which was formed (14 June 1775) to fight the American Revolutionary War

Army
considers itself descended from the Continental Army, and dates its institutional inception from the origin of that armed force in 1775.[10] As a uniformed military service, the U.S. Army
Army
is part of the Department of the Army, which is one of the three military departments of the Department of Defense. The U.S. Army
Army
is headed by a civilian senior appointed civil servant, the Secretary of the Army
Army
(SECARMY) and by a chief military officer, the Chief of Staff of the Army
Army
(CSA) who is also a member of the Joint Chiefs of Staff. It is the largest military branch, and in the fiscal year 2017, the projected end strength for the Regular Army
Army
(USA) was 476,000 soldiers; the Army National Guard (ARNG) had 343,000 soldiers and the United States
United States
Army Reserve (USAR) had 199,000 soldiers; the combined-component strength of the U.S. Army
Army
was 1,018,000 soldiers.[4] As a branch of the armed forces, the mission of the U.S. Army
Army
is "to fight and win our Nation's wars, by providing prompt, sustained, land dominance, across the full range of military operations and the spectrum of conflict, in support of combatant commanders".[13] The branch participates in conflicts worldwide and is the major ground-based offensive and defensive force of the United States.

The Continental Army
Army
was created on 14 June 1775 by the Second Continental Congress[16] as a unified army for the colonies to fight Great Britain, with George Washington
George Washington
appointed as its commander.[10][17][18][19] The army was initially led by men who had served in the British Army
Army
or colonial militias and who brought much of British military heritage with them. As the Revolutionary War progressed, French aid, resources and military thinking influenced 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 in the South in 1780–1781, sometimes used the Fabian strategy and hit-and-run tactics, hitting where 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
Philadelphia campaign
in 1777. With a decisive victory at Yorktown and the help of the French, the Continental Army
Army
prevailed against the British. After the war, the Continental Army
Army
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, with the exception of 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 realized that it was necessary to field a trained standing army. The Regular Army
Army
was at first very small and after General St. Clair's defeat at the Battle of the Wabash, the Regular Army
Army
was reorganized as the Legion of the United States, which was established in 1791 and renamed the United States

The War of 1812, the second and last war between the United States
United States
and Great Britain, had mixed results. The U.S. Army
Army
did not conquer Canada but it did destroy Native American resistance to expansion in the Old Northwest and it validated its independence by stopping two major British invasions in 1814 and 1815. After taking control of Lake Erie in 1813, the U.S. Army
Army
seized parts of western Upper Canada, burned York and defeated Tecumseh, which caused his Western Confederacy
Western Confederacy
to collapse. Following U.S. victories in the Canadian province of Upper Canada, British troops who had dubbed the U.S. Army
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 a status quo ante bellum. Two weeks after a treaty was signed (but not ratified), Andrew Jackson
Andrew Jackson
defeated the British in the Battle of New Orleans

and Siege of Fort St. Philip, 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
United States
and Great Britain) returned to 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
Florida
where there 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.[20] The U.S. Army

fought and won the Mexican–American War

(1846–1848), which was a defining event for both countries.[21] The U.S. victory resulted in acquisition of territory that eventually became all or parts of the states of California, Nevada, Utah, Colorado, Arizona, Wyoming

and New Mexico. American Civil War[edit] Further information: Union Army

The Battle of Gettysburg, the turning point of the American Civil War

The American Civil War
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
Army
officers, mobilized a large fraction of Southern white manpower. Forces of the United States
United States
(the "Union" or "the North") formed the Union Army, consisting of a small body of regular army units and a large body of volunteer units raised from every state, north and south, except South Carolina.[22] For the first two years Confederate forces did well in set battles but lost control of the border states.[23] The Confederates had the advantage of defending a large territory in an area where disease caused twice as many deaths as combat. The Union pursued 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
Vicksburg Campaign
of 1862–1863, General Ulysses Grant

seized the Mississippi River

and cut off the Southwest. Grant took command of Union forces in 1864 and after a series of battles with very heavy casualties, he had General Robert E. Lee

under siege in Richmond as General William T. Sherman captured Atlanta and marched through Georgia and the Carolinas. The Confederate capital was abandoned in April 1865 and Lee subsequently surrendered his army at Appomattox Court House. All other Confederate armies surrendered within 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.[24] Later 19th century[edit]

With the armistice in November 1918, the army once again decreased its forces. In 1939, estimates of the Army's strength range between 174,000 and 200,000 soldiers, smaller than that of Portugal's, which ranked it 17th or 19th in the world in size. General George C. Marshall

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, the Netherlands

began in 1950, when the Soviets walked out of a U.N. Security Council meeting, removing their possible veto. Under a United Nations

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 1953. 1960–1970[edit] The Vietnam War
Vietnam War
is often regarded as a low point for the U.S. Army
Army
due to the use of drafted personnel, 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
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 the guerrilla hit and run tactics of the communist Viet Cong and the North Vietnamese Army. On a tactical level, U.S. soldiers (and the U.S. military as a whole) did not lose a sizable battle.[29]

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
Army
National Guard and the Army
Army
Reserve.[30] In 1967, Secretary of Defense Robert McNamara
Robert McNamara
decided that 15 combat divisions in the Army
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 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
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. 1970–1990[edit]

in the aftermath of the Vietnam War

and involves treating the three components of the army – the Regular Army, the Army

National Guard and the Army

Reserve as a single force.[31] Believing that no U.S. President should be able to take the United States
United States
(and more specifically the U.S. Army) to war without the support of the U.S. people, General Abrams intertwined the structure of the three components of the army in such a way as to make extended operations impossible, without the involvement of both the Army National Guard and the Army
Army
Reserve.[32] The 1980s was mostly a decade of reorganization. The army converted to an all-volunteer force with greater emphasis on training and technology. The Goldwater-Nichols Act
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 a role in the invasions of Grenada

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.[33] A number of incentives such as early retirement were used. 1990s[edit]

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
Battle of Norfolk
and the Battle of 73 Easting were tank battles of historical significance.[34][35][36] 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,[37] but in 2004, Air War College
Air War College
scholars concluded the guidance would reverse the Total Force Policy which is an "essential ingredient to the successful application of military force."[38] 21st century[edit]

in 2003. It served as the primary source for ground forces with its ability to sustain short and long-term deployment operations. In 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.[41][42] 23,813 insurgents[43] were killed in Iraq
Iraq
between 2003–2011. Until 2009, the army's chief modernization plan, its most ambitious since World War II,[44] was the FCS program. In 2009, many systems were canceled and the remaining were swept into the BCT modernization program.[45] In response to Budget sequestration in 2013, the army is planned to shrink to a size not seen since the World War II buildup.[46] From 2016 to 2017, the army retired hundreds of OH-58 Kiowa Warrior observation helicopters without an adequate successor.[47] The 2015 expenditure for Army
Army
research, development and acquisition changed from $32 billion projected in 2012 for FY15 to $21 billion for FY15 expected in 2014.[48] By 2017, the Brigade Modernization project was completed and its headquarters, the Brigade Modernization Command, was renamed the Joint Modernization Command, or JMC, to reflect its evolving mission at TRADOC.[49] (TRADOC is the Army

The task of organizing the U.S. Army
Army
commenced in 1775.[52] In the first one hundred years of its existence, the United States
United States
Army
Army
was maintained as a small peacetime force to man permanent forts and perform other non-wartime duties such as engineering and construction works. During times of war, the U.S. Army
Army
was augmented by the much larger United States
United States
Volunteers which were raised independently by various state governments. States also maintained full-time militias which could also be called into the service of the army. By the twentieth century, the U.S. Army
Army
had mobilized the U.S. Volunteers on four separate 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.[53] It was demobilized at the end of World War I, and was replaced by the Regular Army, the Organized Reserve Corps and 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.[54] In 1941, the " Army
Army
of the United States" was founded to fight World War II. The Regular Army, Army
Army
of the United States, the National Guard and Officer/Enlisted Reserve Corps (ORC and ERC) existed simultaneously. After World War II, the ORC and ERC were combined into the United States
United States
Army
Army
Reserve. The Army
Army
of the United States
United States
was re-established for the Korean War
Korean War
and Vietnam War
Vietnam War
and was demobilized upon the suspension of the draft.[54] Currently, the Army
Army
is divided into the Regular Army, the Army
Army
Reserve and the Army
Army
National Guard.[53] Some states further maintain state defense forces, as a type of reserve to the National Guard, while all states maintain regulations for state militias.[55] 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 unorganized militia has never been activated in the history of the United States, and by law this would only be done in the event of an extreme national emergency, such as a mainland invasion of the United States.[56] The U.S. Army
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 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
Special
Forces, operate similarly to functional areas in that individuals may not join their ranks until having served in another Army
Army
branch.

Before 1903, members of the National Guard were considered state soldiers unless federalized (i.e., activated) by the President. Since the Militia
Militia
Act of 1903, all National Guard soldiers have held dual status: as National Guardsmen under the authority of the governor of their state or territory and when activated as a reserve of the U.S. Army
Army
under the authority of the President. Since the adoption of the total force policy, in the aftermath of the Vietnam
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. Army

The U.S. Army
Army
is made up of three components: the active component, the Regular Army; and two reserve components, the Army
Army
National Guard and the Army
Army
Reserve. Both reserve components are primarily composed of part-time soldiers who train once a month – known as battle assemblies or unit training assemblies (UTAs) – and conduct two to three weeks of annual training each year. Both the Regular Army
Army
and the Army
Army
Reserve are organized under Title 10 of the United States Code, while the National Guard is organized under Title 32. While the Army
Army
National Guard is organized, trained and equipped as a component of the U.S. Army, when it is not in federal service it is under the command of individual state and territorial governors. However, the District of Columbia National Guard reports to the U.S. President, not the district's mayor, even when not federalized. Any or all of the National Guard can be federalized by presidential order and against the governor's wishes.[79] The U.S. Army
Army
is led by a civilian Secretary of the Army, who has the statutory authority to conduct all the affairs of the army under the authority, direction and control of the Secretary of Defense.[80] 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 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.[81][82] In 1986, the Goldwater–Nichols Act
Goldwater–Nichols Act
mandated that operational control of 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 the combatant commanders for use as directed by the Secretary of Defense.[83]

By 2013, the army shifted to six geographical commands that align with the six geographical unified combatant commands (COCOM):

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 is that each brigade will be modular, i.e., all brigades of the same type will be exactly the same and thus any brigade can be commanded by any division. As specified before the 2013 end-strength re-definitions, the three major types of ground combat brigades are:

Armored brigades, with strength of 4,743 troops as of 2014. Stryker
Stryker
brigades, with strength of 4,500 troops as of 2014. Infantry brigades, with strength of 4,413 troops as of 2014.

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 battlefield surveillance brigades. Combat service support
Combat service support
brigades include sustainment brigades and come in several varieties and serve the standard support role in an army. Combat maneuver organizations[edit]

The U.S. Army

currently consists of 10 active divisions and one deployable division headquarters (7th Infantry Division) as well as several independent units. The force is in the process of contracting after several years of growth. In June 2013, the Army
Army
announced plans to downsize to 32 active combat brigade teams by 2015 to match a reduction in active duty strength to 490,000 soldiers. Army
Army
Chief of Staff Raymond Odierno projected that the Army

was to shrink to "450,000 in the active component, 335,000 in the National Guard and 195,000 in U.S. Army

Reserve" by 2018.[84] However, this plan was scrapped by the new administration and now the Army
Army
plans to grow by 16,000 soldiers to a total of 476,000 by October 2017. The National Guard and the Army

United States
Military Academy, Reserve Officers' Training Corps and Officer Candidate School. Regardless of which road an officer takes, the insignia are the same. Certain professions including physicians, pharmacists, nurses, lawyers and chaplains are commissioned directly into the army and are designated by insignia unique to their staff community. Most army commissioned officers are promoted based on an "up or out" system. The Defense Officer Personnel Management Act
Defense Officer Personnel Management Act
of 1980 establishes rules for timing of promotions and limits the number of officers that can serve at any given time. Army
Army
regulations call for addressing all personnel with the rank of general as "General (last name)" regardless of the number of stars. Likewise, both colonels and lieutenant colonels are addressed as "Colonel (last name)" and first and second lieutenants as "Lieutenant (last name)".[94]

They are initially appointed as warrant officers (in the rank of WO1) by the Secretary of the Army, but receive their commission upon promotion to chief warrant officer two (CW2). By regulation, warrant officers are addressed as "Mr. (last name)" or "Ms. (last name)" by senior officers and as "sir" or "ma'am" by all enlisted personnel.[94] However, many personnel address warrant officers as "Chief (last name)" within their units regardless of rank.

Training in the U.S. Army
Army
is generally divided into two categories – individual and collective. Basic training
Basic training
consists of 10 weeks for most recruits followed by Advanced Individualized Training (AIT) where they receive training for their military occupational specialties (MOS). Some individuals MOSs range anywhere from 14–20 weeks of One Station Unit Training (OSUT), which combines Basic Training and AIT. The length of AIT school varies by the MOS The length of time spent in AIT depends on the MOS of the soldier and some highly technical MOS training may require many months (e.g., foreign language translators). Depending on the needs of the army, Basic Combat Training for combat arms soldiers is conducted at a number of locations, but two of the longest-running are the Armor School and the Infantry School, both at Fort Benning, Georgia. Following their basic and advanced training at the individual-level, soldiers may choose to continue their training and apply for an "additional skill identifier" (ASI). The ASI allows the army to take a wide-ranging MOS and focus it into a more specific MOS. For example, a combat medic, whose duties are to provide pre-hospital emergency treatment, may receive ASI training to become a cardiovascular specialist, a dialysis specialist or even a licensed practical nurse. For commissioned officers, training includes pre-commissioning training, known as Basic Officer Leader Course A, either at USMA or via ROTC, or by completing OCS. After commissioning, officers undergo branch specific training at the Basic Officer Leaders Course B, (formerly called Officer Basic Course), which varies in time and location according their future assignments. Officers will continue to attend standardized training at different stages of their career.

Collective training at the unit level takes place at the unit's assigned station, but the most intensive training at higher echelons is conducted at the three combat training centers (CTC); the National Training Center (NTC) at Fort Irwin, California, the Joint Readiness Training Center (JRTC) at Fort Polk, Louisiana

program.[101] Soldiers are also equipped with various hand grenades, such as the M67 fragmentation grenade and M18 smoke grenade. Many units are supplemented with a variety of specialized weapons, including the M249 SAW (Squad Automatic Weapon), to provide suppressive fire at the squad level.[102] Indirect fire is provided by the M320 grenade launcher. The M1014 Joint Service Combat Shotgun or the Mossberg 590 Shotgun are used for door breaching and close-quarters combat. The M14EBR is used by designated marksmen. Snipers use the M107 Long Range Sniper Rifle, the M2010 Enhanced Sniper Rifle and the M110 Semi-Automatic Sniper Rifle.

Crew served weapons

The army employs various crew-served weapons to provide heavy firepower at ranges exceeding that of individual weapons. The M240 is the U.S. Army's standard Medium Machine Gun.[103] The M2 heavy machine gun is generally used as a vehicle-mounted machine gun. In the same way, the 40 mm MK 19 grenade machine gun is mainly used by motorized units.[104] The U.S. Army
Army
uses three types of mortar for indirect fire support when heavier artillery may not be appropriate or available. The smallest of these is the 60 mm M224, normally assigned at the infantry company level.[105] At the next higher echelon, infantry battalions are typically supported by a section of 81 mm M252 mortars.[106] The largest mortar in the army's inventory is the 120 mm M120/M121, usually employed by mechanized units.[107] Fire support for light infantry units is provided by towed howitzers, including the 105 mm M119A1[108] and the 155 mm M777 (which will replace the M198).[109] The U.S. Army
Army
utilizes a variety of direct-fire rockets and missiles to provide infantry with an Anti-Armor Capability. The AT4
AT4
is an unguided projectile that can destroy armor and bunkers at ranges up to 500 meters. The FIM-92 Stinger

doctrine puts a premium on mechanized warfare. It fields the highest vehicle-to-soldier ratio in the world as of 2009.[110] The army's most common vehicle is the High Mobility Multipurpose Wheeled Vehicle (HMMWV), commonly called the Humvee, which is capable of serving as a cargo/troop carrier, weapons platform and ambulance, among many other roles.[111] While they operate a wide variety of combat support vehicles, one of the most common types centers on the family of HEMTT
HEMTT
vehicles. The M1A2 Abrams is the army's main battle tank,[112] while the M2A3 Bradley is the standard infantry fighting vehicle.[113] Other vehicles include the Stryker,[114] the M113 armored personnel carrier[115] and multiple types of Mine Resistant Ambush Protected (MRAP) vehicles. The U.S. Army's principal artillery weapons are the M109A6 Paladin self-propelled howitzer[116] and the M270 Multiple Launch Rocket System (MLRS),[117] both mounted on tracked platforms and assigned to heavy mechanized units. While the United States

Combat Uniform (ACU) currently features a digital Universal Camouflage Pattern (UCP) and is designed for use in woodland, desert and urban environments. However, soldiers operating in Afghanistan and trainees in Basic Combat Training (as of 2017),[124] are being issued a fire-resistant ACU with the "MultiCam" pattern, officially known as Operation Enduring Freedom Camouflage Pattern or "OCP".[125]

The standard garrison service uniform is the Army
Army
Service Uniform, which functions as both a garrison uniform (when worn with a white shirt and necktie) and a dress uniform (when worn with a white shirt and either a necktie for parades or a bow tie for after six p.m. or black tie events). Berets[edit] The U.S. Army's black beret is no longer worn with the new ACU for garrison duty, having been permanently replaced with the patrol cap. After years of complaints that it was not suited well for most work conditions, Army
Army
Chief of Staff General Martin Dempsey eliminated it for wear with the ACU in June 2011. Soldiers still wear berets who are currently in a unit in jump status, whether the wearer is parachute-qualified or not (maroon beret). Members of the 75th Ranger Regiment and the Airborne and Ranger Training Brigade
Brigade
(tan beret) and Special
Special
Forces (rifle green beret) may wear it with the Army
Army
Service Uniform for non-ceremonial functions. Unit commanders may still direct the wear of patrol caps in these units in training environments or motor pools. Tents[edit] The Army
Army
has relied heavily on tents to provide the various facilities needed while on deployment. The most common tent uses for the military are as temporary barracks (sleeping quarters), DFAC buildings (dining facilities), forward operating bases (FOBs), after action review (AAR), tactical operations center (TOC), morale, welfare and recreation (MWR) facilities, as well as security checkpoints. Furthermore, most of these tents are set up and operated through the support of Natick Soldier
Soldier
Systems Center. The U.S. Army
Army
is beginning to use a more modern tent called the deployable rapid assembly shelter or DRASH. In 2008, DRASH became part of the Army's Standard Integrated Command Post System.[126] 3D printing[edit] In November 2012, the U.S. Army
Army
developed a tactical 3D printing capability to allow it to rapidly manufacture critical components on the battlefield.[127] See also[edit]
