The Air Defense Artillery is responsible for defending geopolitical assets and providing maneuver forces with the freedom to move on the battlefield by deterring the enemy and destroying aerial threats, missile attacks, and surveillance platforms.<ref name="auto9">{{cite web | url=https://sill-www.army.mil/ocada/ada.html | title=OCADA &#124; Fort Sill &#124; Oklahoma &#124; Fires Center of Excellence }}</ref> Weapons employed by Air Defense Artillery include the [[FIM-92 Stinger]] [[man-portable air-defense system]], [[AN/TWQ-1 Avenger]], for [[short range air defense]], and the [[counter rocket, artillery, and mortar]] 20mm gun system. The [[Iron Dome]] provides air defense against rockets, artillery, mortars, missiles, and unmanned aerial vehicles, while the [[MIM-104 Patriot]] is capable of defeating a wide range of threats including aircraft, helicopters, UAVs, ballistic and cruise missiles, and Weapons of Mass Destruction.<ref name="auto9"/>

The [[Terminal High Altitude Area Defense]] protects strategic critical assets by conducting long-range endo-and-exo-atmospheric engagements of ballistic missiles using the world's largest air-transportable X-band radar. The [[Ground-Based Midcourse Defense]] is an [[anti-ballistic missile]] system operated by [[Army Space and Missile Defense Command]] to defend the United States homeland against an intercontinental ballistic missile attack.<ref name="auto9"/> Major Air Defense Artillery units include the [[32nd Army Air and Missile Defense Command]] and Army Space and Missile Defense Command's [[100th Missile Defense Brigade]].<ref>{{cite web | url=https://www.army.mil/32ndAAMDC | title=32nd Army Air and Missile Defense Command }}</ref><ref>{{cite web | url=https://www.smdc.army.mil/ORGANIZATION/100thMDB/ | title=100th Missile Defense Brigade }}</ref>

Air Defense Artillery has an extremely close relationship with the Air Force through its Air and Missile Defense Commands and the Space Force through Army Space and Missile Defense Command, given their shared missile defense and space roles. In 1962, Air Defense Artillery achieved the first intercept of a ballistic missile with a nuclear-tipped [[Nike Zeus]] and operated the Nike Zeus as an [[anti-satellite weapon]] after completing a successful intercept in 1963.<ref>{{cite web|url=https://www.smdc.army.mil/Portals/38/Documents/Publications/History/SMDC%20History%20Booklet_508_Final.pdf|title=A Chronological Review of 60 Years|website=smdc.army.mil}}</ref><ref>{{Cite web|url=https://www.ausa.org/articles/realign-air-defense-structure|title=Realign Air Defense Structure|date=23 June 2021|website=AUSA}}</ref>

[[File:Cav troopers conduct maneuver operations 140713-A-HD608-014.jpg|thumb|Formation of [[UH-60 Blackhawk]]s with the [[1st Cavalry Division (United States)|1st Cavalry Division]]]]

Army Aviation, distinct from the U.S. Air Force and its predecessors, began as part of the field artillery in 1942. Small spotter planes were used to spot for artillery and naval bombardment, as well as to perform observation. These few aircraft formed the core of Army Aviation once the U.S. Air Force gained independence. In 1983, the Army created the Aviation Branch, for the first time since the Air Force's independence consolidating aviation under a single organization.<ref>{{cite web | url=https://www.armyaviationmuseum.org/discover/ | title=Discover | date=27 October 2016 }}</ref>

The mission of Army Aviation is to find, fix and destroy any enemy through fire and maneuver and to provide combat support and combat service support in coordinated operations as an integral member of the combined arms team.<ref>{{cite web | url=https://www.army.mil/aviation/modern/ | title=Modern Aviation - United States Army Aviation }}</ref> Major aircraft include the [[AH-64 Apache]], which serves as the Army's attack helicopter, the [[UH-60 Black Hawk]], and the [[CH-47 Chinook]] for troop and cargo transport. Army Aviation also flies the [[MQ-1C Gray Eagle]] drone.<ref>{{cite web | url=https://asc.army.mil/web/portfolio-item/aviation_gray-eagle-uas/ | title=MQ-1C Gray Eagle Unmanned Aircraft System (UAS) - USAASC }}</ref>

A specialized unit within Army Aviation, the [[160th Special Operations Aviation Regiment (Airborne)]] serves as a special operations unit and operates modified variants of the MH-60 Black Hawk, MH-47 Chinook, and the [[MH-6 Little Bird]].<ref>{{cite web | url=https://www.soc.mil/USASOAC/160th.html | title=160th SOAR (A) Page }}</ref>

====Army commands====
The U.S. Army is organized into four major Army Commands, nine [[Army Service Component Command]]s, which serve as the Army component and [[Joint Force Land Component Commander|joint force land component commander]]s for the [[unified combatant command]]s, and thirteen direct reporting units.<ref>{{Cite web|url=https://www.army.mil/organization/|title=Organization &#124; The United States Army|website=Organization &#124; The United States Army}}</ref>
