Structure of the United States Army
Encyclopedia
The Structure of the United States Army
is complex, and able to be seen in several different ways: active/reserve, operational/administrative, and headquarters/field.
This page aims to portray the current central structure of the US Army, perhaps in the future the former central structure (including Army Ground Forces
, Army Service Forces
, and Army Air Forces) and both present and historical combat formations (armies, corps, and brigades).
and the Army Reserve
. Both reserve components are primarily composed of part-time soldiers who train once a month, known as Battle Assembly
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
. 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, individual units are under the command of individual state's governors. However, units of the National Guard
can be federalized by presidential order and against the governor's wishes.
During the First World War, the "National Army" was organized to fight the conflict. 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.
In 1941, the "Army of the United States
" was founded to fight the Second World War. 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, 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 United States National Guard
. Prior to 1903 members of the National Guard were considered state soldiers unless federalized by the President. Since the Militia Act of 1903
all National Guard soldiers have held dual status: as National Guardsmen under the authority of the governor of their state and as a reserve of the U.S. Army under the authority of the President.
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. Reserve and Guard units took part in the Gulf War
, peacekeeping in Kosovo
, and the 2003 invasion
of Iraq
.
Although the present-day Army exists as an all volunteer force, augmented by Reserve and National Guard forces, measures exist for emergency expansion in the event of a catastrophic occurrence, such as a large scale attack against the U.S. or the outbreak of a major global war
.
The final stage of Army mobilization, known as "activation of the unorganized militia" would effectively place all able bodied males in the service of the U.S. Army. The last time an approximation of this occurred was during the American Civil War
when the Confederate States of America
activated the "Home Guard" in 1865, drafting all males, regardless of age or health, into the Confederate Army.
The U.S. Army is led by a civilian Secretary of the Army
, who reports to the Secretary of Defense
, and serves as civilian oversight for the U.S. Army Chief of Staff. The U.S. Army Chief of Staff is a member of the Joint Chiefs of Staff
, a body composed of the service chiefs from each service who advise the President
and Secretary of Defense on military matters under the guidance of the Chairman and Vice Chairman of the Joint Chiefs of Staff.
Each command will eventually have a numbered army as operational command, except in the case of U.S. Army Pacific, which will not maintain one but will have a numbered army for U.S. Army forces in the Republic of Korea.
indicates, the US Army has had over 70 divisions in its twentieth century history. As an overview page, listing them all would distort the page. The compromise is to go "one back" and list the divisions as of peak strength during the Cold War, after the Reagan expansion had resulted in a force of 18 active and ten ARNG divisions.

The last time a multiple-corps army took the field was Third Army directing VII and XVIII Corps during Operation Desert Storm.

Armies have also effectively operated as military districtMilitary districtMilitary districts are formations of a state's armed forces which are responsible for a certain area of territory.

. Since the Brigade Unit of Action program was initiated, maneuver brigades have transformed into brigade combat teams, generally consisting of two maneuver battalions, a cavalry squadron, a fires battalion, a special troops battalion (with engineers, signals, and military intelligence), and a support battalion. Stryker Brigade Combat Teams have a somewhat larger structure. 3,000–5,000 soldiers. - Regiment: The Army, for the most part is no longer organized by Regiments. Rather, Battalions and Squadrons maintain Regimental Affiliations in that they are called (for example), 1st Battalion, 8th Infantry (Regiment is implied) and is written 1–8 Inf. In this case, there is no Regimental Commander and the Battalion is organized as part of a Brigade for combat. The exceptions are those units, such as Armored Cavalry Regiments which remain organized, and fight, as a Regiment and have a Regimental Commander. The written designation is easy to distinguish and commonly misused. A "/" separates levels of command. 1st Squadron, 3rd Armored Cavalry Regiment is written 1/3 ACR whereas the 1st Battalion, 6th Field Artillery (again, Regiment is implied) is written 1–6 FA.
