1st Armored Brigade Combat Team (1st ABCT) is an armored brigade combat team of the United States Army assigned to the 1st Infantry Division stationed at Fort Riley, Kansas. The brigade traces its lineage through armored and infantry formations that served in major conflicts including World War II, the Korean War, the Vietnam War, and operations in Iraq and Afghanistan. As a combined arms formation it integrates M1 Abrams, M2 Bradley, artillery, engineering, and sustainment elements for expeditionary armored operations.

History

Formed from predecessor units of the 1st Infantry Division and elements of the 2nd Armored Division after reorganizations in the late 20th century, the brigade draws heritage from campaigns such as the Normandy Campaign, the Battle of the Bulge, the Anzio landings, and the Rhine crossing. During the Cold War its antecedents were involved in NATO deployments to West Germany alongside formations like the V Corps and units of the British Army of the Rhine. In the post-Cold War era the brigade's lineage includes service in Operations Desert Shield and Desert Storm, rotations for Operation Iraqi Freedom, deployments under Multi-National Force – Iraq, and contributions to Operation Enduring Freedom in Afghanistan.

Organization and Structure

The brigade is organized as an armored brigade combat team under the Brigade Combat Team modular design, typically comprising combined arms battalions, a cavalry reconnaissance squadron, a field artillery battalion, an engineer battalion, and a brigade support battalion. Key subordinate elements often reference battalions formerly assigned to the 1st Infantry Division and paired with maneuver elements similar to those in the 3rd Armored Division and the 4th Infantry Division during modular transformations. Command relationships include operational alignment with U.S. Army Forces Command and training support from U.S. Army Combined Arms Center institutions at Fort Leavenworth.

Equipment and Vehicles

The brigade fields main battle tanks such as the M1 Abrams series, infantry fighting vehicles like the M2 Bradley, combined with armored reconnaissance vehicles such as the M3 Bradley and supported by tracked engineer vehicles like the M1150 Assault Breacher Vehicle. Artillery support has included the M109 Paladin self-propelled howitzer and fire control from systems influenced by the Advanced Field Artillery Tactical Data System. Sustainment platforms include the M1070 Heavy Equipment Transporter and logistics vehicles from Tactical Wheeled Vehicle families, while airspace coordination leverages assets akin to MQ-1 Predator and RQ-7 Shadow for reconnaissance during recent operations.

Training and Exercises

The brigade conducts collective training at institutions and ranges including the National Training Center at Fort Irwin, the Joint Readiness Training Center at Fort Polk, and multinational exercises such as Exercise Saber Strike and Operation Atlantic Resolve. Training cycles integrate doctrine from the U.S. Army Training and Doctrine Command and employ live-fire exercises, combined arms maneuver rotations, and interoperability drills with partner forces from NATO members including United Kingdom, Germany, Poland, and Lithuania. Pre-deployment preparations often involve certification events under U.S. Central Command and validation against standards set by U.S. Army Forces Command.

Deployments and Operations

The brigade or its antecedent battalions have been deployed in major operations including Operation Desert Storm, Operation Iraqi Freedom, and Operation Enduring Freedom. During Iraq War rotations units conducted counterinsurgency, stability operations, and partnered training with Iraqi Security Forces and Provincial Reconstruction Teams tied to Multi-National Corps – Iraq. In Afghanistan elements supported provincial stability, route security, and advise-and-assist missions alongside units from ISAF and NATO Resolute Support Mission. The brigade has also participated in deterrence and reassurance missions in Europe under Operation Atlantic Resolve and in large-scale combat training against peer and near-peer adversaries.

Honors and Insignia

Lineage and honors trace to decorations and campaign streamers awarded for service in campaigns such as Normandy, Northern France, Rhineland, Ardennes-Alsace, and later decorations for service in Iraq and Afghanistan. Unit citations linked to the brigade's history include awards similar to the Presidential Unit Citation, Valorous Unit Award, and campaign medals associated with European Theater of Operations (World War II). The brigade's shoulder sleeve insignia, distinctive unit insignia, and unit heraldry reflect ties to the 1st Infantry Division and armored traditions symbolized in heraldic elements adopted by the U.S. Army Institute of Heraldry.
