The Regular Army of the United States succeeded the Continental Army as the country's permanent, professional land-based military force. In modern times, the professional core of the United States Army continues to be called the Regular Army (often abbreviated as "RA"). From the time of the American Revolution until after the Spanish–American War , state militias and volunteer regiments organized by the states (but thereafter controlled by federal authorities and federal generals in time of war) supported the smaller Regular Army of the United States. These volunteer regiments came to be called United States Volunteers (USV) in contrast to the Regular United States Army (USA). During the American Civil War , about 97 percent of the Union Army was United States Volunteers.
112-897: United States Army Forces in the Middle East (USAFIME) was a unified United States Army command during World War II established in August, 1942 by order of General George C. Marshall , the Chief of Staff of the United States Army , to oversee the Egypt-Libya campaign . The small USAFIME was headquartered in Cairo —which simplified liaison with its much larger British counterpart, Middle East Command . USAFIME had command over all United States Army forces in North Africa and

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
336-465: A colonel of volunteers, and a brevet brigadier general. After the Civil War ended in 1865, the term Regular Army was used to denote an officer's permanent rank only when a brevet commission had also been received. Such was the case with George Custer who was a brevet major general of volunteers and a brevet Regular Army brigadier general while holding the permanent rank of lieutenant colonel in

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
672-483: 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,

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
1120-402: A permanent rank (called "full rank") in the Regular Army, a full rank in the volunteers, and brevet ranks in both as a result of battlefield promotion, meritorious service or congressional action. The officers typically would only refer to themselves by the highest rank they held. An example is Union Army officer James Henry Carleton who was a "full" captain, a brevet major in the regular army,
1232-629: A permanent rank in the Regular Army and a temporary rank in the Army of the United States . Promotions within the Army of the United States were also very rapid and some officers were known to hold the permanent Regular Army rank of captain while serving as a colonel in the Army of the United States. The Army of the United States rank could also be revoked (sometimes known as "loss of theater rank") meaning that an officer would revert to Regular Army rank and, in effect, be demoted. Enlisted personnel did not hold dual ranks; rather, they were soldiers either in

After Vietnam, most Reserve Officers' Training Corps (ROTC) and Officer Candidate School (OCS) graduates, and those receiving direct commissions were commissioned as RA, US Army Reserve (USAR), or into the Army National Guard of the United States (ARNG). USAR officers could be assessed into the basic USAR component; that is, officers who served one weekend

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
1680-738: A strategy of seizing the coastline, blockading the ports, and taking control of the river systems. By 1863, the Confederacy was being strangled.

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

There was also a powerful motivation for the American government to uphold the United States' national honor in the face of what many Americans considered to be British insults (such as the Chesapeake-Leopard Affair in 1807). In January 1812, with the threat of war with Britain looming larger, Congress authorized

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
2576-894: The Mediterranean Theatre of War were USAAF squadrons. As plans for Operation Torch began to take shape it became clear that the Americans would not contribute ground troops to the Western Desert Campaign. This was reflected in Maxwell's replacement by Andrews. One of Andrew's first acts was to establish the Ninth Air Force to replace the United States Army Middle East Air Force (USAMEAF). The non-air force administrative functions of USAFIME were taken over by

That is, all non-permanent ranks (including theater rank, temporary rank, battlefield promotions, etc.) are handled through USAR commissions. Those officers without RA commissions do not have
8288-685: 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
8400-471: 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

During the American Civil War , the Union Army consisted of a very small contingent of pre-war U.S. Army or "Regular Army" personnel combined with vast numbers of soldiers in state volunteer regiments raised and equipped by the States before being "federalized" and led by general officers appointed by the president of
8960-449: 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
9072-608: 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,
9184-432: The new regiments honored their foundations: In 1808, Congress agreed to the expansion of the Regular Army. This led to the establishment of the 5th, 6th and 7th Regular infantry regiments, and a Regiment of Riflemen .

Although raised as Regulars, the nine new infantry regiments created during
9632-599: The professional military while, as in the Union Army, the Confederacy mustered massive numbers of state volunteers into the "Provisional Army of the Confederate States" or the "PACS".

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
10192-456: 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
10304-533: 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.

11536-677: The war and disbanded at its end. In 1821 Congress felt safe enough to cut expenses by disbanding the Rifle Regiment and the 8th Infantry and reducing the size of companies to fifty-one enlisted men, the smallest ever.

As the Revolutionary War progressed, French aid, resources, and military thinking helped shape
11984-523: Was especially difficult, this approach also enabled the Americans to prevail without having had to establish a large or permanent army. As the war waned, General Washington sent his plans for a standing army and organized militia to Congress.

12096-498: Was no winter. The second strategy was to form alliances with other Indian tribes, but that too was useless because the Seminoles had destroyed all the other Indians when they entered Florida in the late eighteenth century. The U.S. Army fought and won the Mexican–American War (1846–1848), which was a defining event for both countries.

Initially, the only US combat forces that were allocated to
12432-476: Was to be apportioned to the states according to their populations. While the initial number of battalions approached the authorized strength, by 1 January 1787 the Continental infantry was only able to maintain enough regiments for fifty battalions. During the Revolutionary War, battalions and regiments were essentially the same. By October 19, 1781, when a British army under General Cornwallis surrendered to
