U.S. Army Combat Arms Regimental System - Units That Participated in CARS

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. (See Appendix A for listing.)
• 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 2d, 3d, 6th, 11th, and 14th Armored Cavalry Regiments. (See Appendix A for listing.)
• There were 82 Regular Army artillery regiments in the Combat Arms Regimental System - 58 field artillery regiments and 24 air defense artillery regiments. (See Appendix A for listing.)
• 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, 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.
