The Benelli M4 is a semi-automatic shotgun produced by Italian firearm manufacturer Benelli Armi SpA , and the fourth and last model of the Benelli Super 90 line of semi-automatic shotguns. The M4 uses a proprietary action design called the "auto-regulating gas-operated" (ARGO) system, which was created specifically for the weapon. Designed in 1998, the M4 was adopted by the armed forces of Italy, the United States, and United Kingdom, among others, and has been used in a variety of conflicts.

In response to the request, Benelli Armi SpA of Urbino , Italy designed and built the Benelli M4 Super 90 Combat Shotgun. On August 4, 1998, five samples of

184-614: 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

276-651: 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

368-534: 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,

460-726: 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 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

552-487: 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

644-480: 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

736-618: 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

828-738: 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

920-460: A visual indication of where the gun is aimed, laser sights add an extra factor of intimidation. Studies of law enforcement indicate that suspects faced with laser sights are significantly more likely to surrender, even if they themselves are armed. IR (infrared) lasers can be used with night vision devices, as the bulk of a head-mounted night vision device makes aiming with iron sights or a conventional optic difficult. These lasers cannot be seen by

1012-600: Is also a member of the Joint Chiefs of Staff . It is the largest military branch, and in the fiscal year 2022, 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,

1104-545: Is collapsible on the M4 Model (designated 11707) and on the M1014. Collapsing the buttstock shortens the weapon by almost 8 in (200 mm), allowing easier storage and transportation; furthermore, it permits better maneuverability around tight corners and over obstacles. The M4 is also available with both pistol grip and semi-grip fixed stocks, with these also being available for the M1014. The Picatinny rail built into

1196-448: 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 the theater for the joint force, and to integrate national, multinational, and joint power on land. The Continental Army

1288-533: 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. The U.S. Army is led by a civilian secretary of the Army , who has

1380-421: Is sold in three configurations: M4 Entry with a 14 in (360 mm) barrel; M4 with an 18.5 in (470 mm) barrel; and M1014, which is an M4 with the "M1014" nomenclature on it for military usage only. M4 shotguns sold through Benelli Tactical are available with the collapsible buttstock. Benelli Tactical and Beretta LE have maintained the belief that the collapsible stock , while no longer illegal in

1472-670: 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 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

1564-420: Is that the beam widens over distance, meaning that instead of projecting a small dot, a much larger circle may be produced. Visibility of laser sights deteriorates in bright light. Green lasers are more effective in bright conditions, however they are more complex to produce so are often larger and more expensive than red lasers. Laser sights cannot be used for hunting flying game in the daylight, as neither

1656-537: 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

1748-912: The Continental Army , which was formed on 14 June 1775 to fight against the British for independence during 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

1840-707: The Netherlands and the United Kingdom , until the 1990s in anticipation of a possible Soviet attack. 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

1932-439: The U.S. Military , its allies, and law enforcement. The use of laser sights is associated with increased accuracy in general, increasing the probability of hitting the target especially in low light conditions. The projected dot speeds up target acquisition, decreasing the time required for the shooter to aim and fire, as well as decreasing the time necessary for follow-up shots. Laser sights also aid in point shooting , where

2024-720: The chamber to function opposite a rotating bolt , thereby eliminating the need for the complex mechanisms found on other gas-actuated automatics. The ARGO incorporates only four parts: two symmetrical fore-end shrouds containing two small steel pistons that push directly against the bolt . Additionally, the weapon is self-regulating for use with shotshells of varying lengths and power levels . It can fire 2.75 in (70 mm) and 3 in (76 mm) shells of differing propellant loads without any operator adjustments and in any combination. Low-power rounds, such as less-lethal baton rounds , must be cycled manually. The sights are military-style ghost ring and are adjustable in

2116-562: The guerrilla hit and run tactics of the communist Viet Cong and the People's Army Of Vietnam (NVA) . 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

2208-697: The point of impact at a chosen distance. Devices may include one or both types of laser, with some models also incorporating a rangefinder, flashlight , or IR illuminator. Laser sights may be attached to the existing sighting mechanism, the trigger guard , via a rail system , or can be integrated into replacement components such as the guide rod or grip plates. Some variants are also incorporated into other attachments such as foregrips . Laser sights are primarily used by military and law enforcement, although have some civilian use for hunting and self defense. They are also found on some less-lethal weapons, such as Taser electroshock weapons . The laser sight

2300-421: The 14.5" barreled model only since this model is considered to be a Short Barreled Shotgun or SBS. Standard magazine capacity of the civilian version is 5+1, although it is possible to fit 6+1 and two shot extension tubes are sold by Benelli as well as some other companies. Also available are 9 + 1 extension tubes, which popular in 3-gun competitions. Some LE models have become available to private individuals on

2392-460: The Army (HQDA): See Structure of the United States Army for a detailed treatment of the history , components , administrative and operational structure and the branches and functional areas of the Army. 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

2484-472: 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

2576-411: 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

2668-624: 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 was quickly given land certificates and disbanded in a reflection of the republican distrust of standing armies. State militias became

2760-461: 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

2852-502: The Colt M16, Remington 870, H&K MP5, and Ruger Mini-14. Laser sights were popularized outside of military and law enforcement when Laser Products fitted The Terminator's iconic weapon, a .45 Longslide pistol , with a custom He-Ne laser. Today, most modern laser sights are solid-state lasers , as opposed to the original gas design. Modern weapon-mounted lasers and combat lights produced by SureFire continue to be widely used by

2944-696: The M4 were delivered to Aberdeen Proving Ground , Maryland , and after intense testing, the M4 won the competition. In early 1999, ARDEC awarded the M1014 Joint Service Combat Shotgun contract to Heckler & Koch , U.S. subsidiary for importation of the Benelli M4 Combat Shotgun. The first 20,000 units were delivered to the United States Marine Corps in 1999. During testing, the prototype

3036-545: 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

3128-585: The ORC and ERC were combined into the United States Army Reserve . 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

3220-635: 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

3312-663: 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

3404-540: The 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 . For the first two years, Confederate forces did well in set battles but lost control of the border states. 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

3496-405: The United States 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 was augmented by the much larger United States Volunteers which were raised independently by various state governments. States also maintained full-time militias which could also be called into

3588-404: The United States, is still only to be made available to law enforcement and government agencies, and thus does not sell them to private individuals; however, Benelli Tactical sells the stock piece for retrofitting the pistol grip stock, which can be shipped from Italy without restrictions. Suggested retail price of the civilian version is around $ 1,899. An NFA stamp is required to purchase or own

3680-423: 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,

3772-491: 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

3864-650: 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

3956-619: 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

4048-404: The beam nor dot are visible. A further risk to aircraft is also an issue, as even civilian grade lasers are capable of hitting a plane from 2 miles away. Laser sights rely on batteries to work. As such, they require regular maintenance and may fail during use. Non-water resistant models also risk electrical damage through water ingress. As with all firearms attachments, laser sights add mass to

4140-662: 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

4232-466: 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

4324-415: The degree of improvement is highly dependent on correct set up of the system. Where a laser beam travels in a straight line, the path of a bullet gradually deviates after it leaves the barrel due to external forces such as gravity, wind, and even the rotation of the earth . This is a significant issue for long distance shooting; shorter range weapons such as handguns are less affected. Another related issue

4416-413: The device to aim at the target, laser sights project a beam onto the target, providing a visual reference point. Although lasers in the visible part of the spectrum are most common, invisible infrared (IR) lasers may be used in conjunction with a night vision device . As they are offset from the barrel, laser sights need to be zeroed in , much like a conventional sight, so that the beam intercepts

4508-631: 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

4600-439: 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

4692-435: The field using only the rim of a shell. The MIL-STD-1913 Picatinny rail on top of the receiver allows use of both conventional optical sights and night-vision devices , while retaining use of the original iron sights. The modular basis of the shotgun means many of its features can be reconfigured as needed. It allows a user to quickly exchange the various assembly groups ( barrel , buttstock , forend , etc.) without

4784-463: The firearm. This is particularly significant for handguns, as many holsters aren't designed to accommodate them. Lasers can easily cause damage to the eyes. Visible lasers are unlikely to cause permanent damage due to the blink reflex, however IR lasers do not trigger this and thus pose a significant risk. The use of laser sights poses a risk in tactical scenarios as they may reveal the user's location, although this can be mitigated by only turning on

4876-580: 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

4968-587: 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

5060-685: 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

5152-471: 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

5244-760: 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, 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

5336-476: The laser when needed. An additional consideration for military and law enforcement is whether the enemy has night vision capabilities; if so, IR lasers will be visible to them. Laser sights are somewhat more difficult to zero than conventional sighting systems. IR lasers in particular can take in excess of an hour to properly zero, depending on the methods used. Laser boresights differ from laser sights in that they are not intended, or capable, of being used at

5428-771: 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,

5520-406: The mission of the U.S. 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 ". 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

5612-522: The naked eye and are only visible when utilizing night vision devices. Some IR laser units, like the AN/PEQ-2 , utilize two separate lasers: a narrow "aiming" laser and a more diffuse "illuminator". The aiming laser is used to estimate point of impact, while the illuminator is used to better visualize targets and the environment through the night vision device. However, even with laser sights, shot groupings are still inferior to those achieved in daytime, and

5704-449: 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 British were weakest to wear down their forces. Washington led victories against

5796-608: 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 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,

5888-413: The origin of that armed force in 1775. The U.S. Army is a uniformed service of the United States and 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 is headed by a civilian senior appointed civil servant, the secretary of the Army (SECARMY), and by a chief military officer , the chief of staff of the Army (CSA) who

5980-436: 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

6072-412: 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

6164-418: The same time as the firearm; instead, they are intended to aid in zeroing the firearm. A boresight is a laser in the shape of a cartridge . The user chambers a boresight of the appropriate calibre which projects a laser beam directly down the barrel, providing a visual indicator of the point of impact at a given range. The user then adjusts the sights until they align with the dot. Boresighting suffers from

6256-429: The same weakness as laser sights in that while the beam is straight, the path of the bullet curves; as such it is not a substitute for traditional zeroing, rather they serve to speed up the process. Restrictions on laser sights vary by jurisdiction. Another consideration is the legality of the laser itself: the power output of military and law enforcement issue devices often exceeds that permitted for civilian use. In

6348-402: The secondary market. United States Army The United States Army ( USA ) is the land service branch of the United States Armed Forces . It is one of the eight U.S. uniformed services , and is designated as the Army of the United States in the U.S. Constitution . The Army is the oldest branch of the U.S. military and the most senior in order of precedence. It has its roots in
