United States Army Combat Arms Regimental System

United States Army Combat Arms Regimental System. The Combat Arms Regimental System was a major reorganization of the United States Army's combat arms branches implemented in 1957. It was designed to replace the old regimental structure, which had been rendered obsolete by the Pentomic division reorganization, with a flexible system that preserved historical lineages. CARS created parent regiments under which multiple active battalions could serve, allowing for the perpetuation of honors and traditions while providing a framework for modern force management.

History and background

The system emerged in the mid-1950s as a direct response to the Pentomic reorganization championed by General Maxwell D. Taylor. This new divisional structure, intended to optimize forces for potential nuclear warfare, eliminated traditional regiments as tactical units, replacing them with battle groups. Army leaders, including those at the United States Army Center of Military History, were concerned that this would sever the vital historical ties and esprit de corps associated with famous regiments from conflicts like the American Civil War, World War I, and World War II. The development of CARS was heavily influenced by the regimental traditions of the British Army and sought to balance modern tactical needs with the preservation of institutional heritage. Its creation was formally authorized by the United States Department of the Army.

Structure and organization

Under CARS, a regiment was a formal organization comprising only its headquarters element, with no command and control function over its subordinate units. The regiment's history, lineage, honors, and distinctive insignia were vested in this headquarters, which was typically inactive. The system's core components were the numbered battalions, which were the active tactical units. Multiple battalions, often serving in different brigades, divisions, or geographical locations like West Germany or South Korea, could carry the designation and lineage of a single parent regiment. For example, the 3rd U.S. Infantry Regiment (The Old Guard) had battalions serving in distinct roles. This structure was applied to the Infantry, Armor, Field Artillery, and Air Defense Artillery Branch of the United States Army.

Regiments under CARS

CARS initially designated 75 historic regiments from the Regular Army, Army National Guard, and Army Reserve as parent organizations. Notable examples included the 1st Infantry Regiment (United States), the 2nd Cavalry Regiment, the 7th Cavalry Regiment, and the 101st Field Artillery Regiment. The system also encompassed famous units with deep histories, such as the 369th Infantry Regiment (United States), the 3rd Armored Cavalry Regiment, and the 82nd Airborne Division's 504th Infantry Regiment. Regiments with storied records from the Mexican–American War, the Spanish–American War, and the Korean War were preserved under this umbrella, maintaining their connections to battle honors from places like Gettysburg, Normandy, and Pork Chop Hill.

Implementation and evolution

The system was fully implemented across the active force and the Army National Guard by 1959. Throughout the 1960s and 1970s, CARS provided a stable framework for unit designation during the Vietnam War, where numerous CARS battalions, such as those from the 23rd Infantry Regiment and the 11th Armored Cavalry Regiment, saw extensive combat. The structure proved adaptable, allowing for the activation and inactivation of battalions as needed for global deployments from Fort Bragg to Panama. However, the 1970s saw a shift in tactical doctrine, and the 1981 adoption of the Army Organization Act and the new Division 86 structure began the process of replacing CARS with a more integrated system.

Impact and legacy

The Combat Arms Regimental System successfully preserved the historical identities of the United States Army during a period of significant tactical upheaval. It maintained a crucial link between contemporary soldiers and the legacy of units that fought at Antietam, the Meuse-Argonne Offensive, and the Battle of the Bulge. CARS directly influenced its successor, the United States Army Regimental System, implemented in 1981, which expanded the regimental concept to all branches. The lineage and honors preserved under CARS continue to be meticulously documented by the United States Army Institute of Heraldry and the United States Army Center of Military History, ensuring the traditions of famed regiments remain a cornerstone of Army culture.
