The '''Combat Arms Regimental System''' ('''CARS'''), was the method of assigning unit designations to [[Military unit|units]] of some of the [[combat arms]] branches of the
[[United States Army]], including [[Infantry]], [[Special Forces (United States Army)|Special Forces]], [[Field Artillery]], and [[Armor Branch|Armor]], from 1957 to 1981. [[Air Defense Artillery Branch (United States)|Air Defense Artillery]] was added in 1968.

CARS was superseded by the [[U.S. Army Regimental System]] (USARS) in 1981, although the term "Regiment" was never appended to the official name or designation of CARS regiments, and was not added to USARS regiments until 2005.

==History==
Before the adoption of CARS, there was no satisfactory means of maintaining the active life of the combat arms organizations. Whenever the nation entered periods of military retrenchment, units were invariably broken up, reorganized, consolidated, or disbanded. During periods of mobilization, large numbers of new units were created. Changes in weapons and techniques of warfare produced new types of units to replace the old ones. As a result, soldiers frequently served in organizations with little or no history, while units with long combat records remained inactive.

In the late 1950s requirements for maneuverable and flexible major tactical organizations demanded highly mobile divisions with greatly increased firepower. For this purpose the regiment was deemed too large and unwieldy and had to be broken up into smaller organizations. (Most artillery and [[tank|armored]] regiments had already been broken up for flexibility and maneuverability during World War II.)

When the U.S. Army [[Division (military)|division]] was reorganized under the [[Pentomic]] structure in 1957, the traditional [[regiment]]al organization was eliminated, raising questions as to what the new units were to be called, how they were to be numbered, and what their relationship to former organizations was to be.

On 24 January 1957 the [[United States Secretary of the Army|Secretary of the Army]] approved the CARS concept, as devised by the Deputy Chief of Staff for Personnel, which was designed to provide a flexible regimental structure that would permit perpetuation of unit history and tradition in the new tactical organization of divisions, without restricting the organizational trends of the future.

==Units that participated in CARS==
* There were 61 Regular Army infantry regiments and 18 Army Reserve infantry regiments, plus the 1st Special Forces, in the Combat Arms Regimental System. 
* There were 30 Regular Army armor/cavalry regiments in the Combat Arms Regimental System. The only Regular Army combat units not organized under CARS were the [[2nd Armored Cavalry Regiment|2nd]], [[3rd Armored Cavalry Regiment|3rd]], [[6th Armored Cavalry Regiment|6th]], [[11th Armored Cavalry Regiment|11th]], and [[14th Armored Cavalry Regiment]]s. 
* There were 82 Regular Army artillery regiments in the Combat Arms Regimental System – 58 field artillery regiments and 24 air defense artillery regiments.
* Except for the 18 Army Reserve infantry regiments, those regiments organized under CARS had elements in both the Regular Army and the Army Reserve. In the Army National Guard, each state has its own regiments. The number of CARS regiments varied as troop allotments change. The 1st Special Forces has elements in all three components – [[Regular Army (United States)|Regular Army]], [[United States Army Reserve|Army Reserve]] and [[Army National Guard]].

The criteria for the majority of the regiments selected were two factors: age (one point for each year since original organization) and honors (two points for each campaign and American decoration). Those regiments with the most points were selected for inclusion in the system.

==CARS implementation phases==

* Phase I: Reorganization of Regular Army regiments (1957)
* Phase II: Reorganization of Army Reserve regiments (1959)
* Phase III: Reorganization of Army National Guard regiments (1959)
* Phase IV: Mobilization planning (1957–present)
* Phase V: Organization of regimental headquarters (subsequently suspended indefinitely)

==Organization==

Each [[company (military unit)|company]], [[battery (military unit)|battery]] or [[troop]] in the [[regiment]] (as originally organized) was reorganized as the headquarters and headquarters element of a new [[Battlegroup (army)|battle group]], [[battalion]], or [[Squadron (army)|squadron]] in the new regiment. The new battle group, battalion, or squadron's organic elements (lettered elements, such as "Company A") were constituted and activated as new units. Each of the old companies, batteries, or troops of the former regiment also had the capability of becoming a separate company, battery, or troop in the new regiment. The regimental headquarters was transferred to [[Department of the Army]] control. (For detailed charts of typical regiments reorganized under CARS, see below '''Illustrations of organization under CARS''')

The lowest numbered or lettered active element of the regiment normally has custody of the regimental properties. If, however, the lowest numbered or lettered active element is unable to care for the properties, they may be transferred to the next lowest numbered or lettered active element. If a numbered or lettered element of the regiment is activated lower than the one having custody of the regimental properties, the properties will not necessarily be transferred.

==Difference between a brigade and a regiment==

In a regiment not organized under CARS, there is a fixed number of organic elements organized into battalions or squadrons. For example, the infantry regiment of [[World War II]] contained twelve companies A through M (minus J – not used) divided into three battalions (of four companies each), plus supporting elements such as the service company.

A [[brigade]], on the other hand, is a flexible organization; it has no permanent elements. A brigade may have several different kinds of units assigned to it, such as: three light infantry battalions '''or''' two mechanized infantry and an armor battalion '''or''' one light, one mechanized and one armor battalion; plus support units. The usual number of maneuver battalions was three; however, this was a guideline not a rule (ex: the 173rd Airborne Brigade in Vietnam had four airborne infantry battalions).

In tactical structure, therefore, it is very similar to the [[Regimental Combat Team]] of World War II and [[Korean War]]. Its maneuver (infantry and armor) elements were not required to be from the same regiment. Since they were flexible, except for the [[headquarters and headquarters company]], no two brigades need be alike, whereas all regiments were fixed with organic elements provided for under basic tables of organization and equipment.

==Battle honors==
Each battalion or squadron of a CARS regiment has a replica of the [[regimental colors]] with the number of the battalion or squadron in the upper fly. The streamers attached to the colors were those for the regiment, as determined when the regiment was reorganized under CARS, plus those subsequently earned by the battalion or squadron.

Those campaigns and decorations actually earned by the battalion or squadron were shown on the streamers by earned honor devices. Regimental honors were listed on the battalion or squadron Lineage and Honors Certificates, with the earned honors being marked by asterisks.

Separate batteries, troops, and companies of CARS regiments display only those honors they actually earned, not the regimental ones. Campaign participation credit for these guidon-bearing units are displayed by silver bands and decorations streamers. (See ARs 672-5-1, 840-10 and 870-5 for further details.) Personnel wear the distinctive insignia for their regiment and the shoulder sleeve insignia of their division or other tactical organization to which they were assigned. (See AR 670-5 for further details.) The Adjutant General controls the designations of elements to be activated and coordinates his selections with the Center of Military History.
