This volume gathers in compact form the official historical records of field artillery units in the United States Army in order to perpetuate and publicize their traditions, honors, and heraldic entitlements. It includes the lineages and honors of Regular Army and Army Reserve field artillery commands, brigades, and groups, and corps and division artillery that have been active since 1965. It also includes the fifty-eight elements of each regiment that have been active since the inception of the Combat Arms Regimental System in 1957. This two-part second edition updates the lineages, honors, and heraldic items of the Regular Army's field artillery regiments and further expands them to include organizations above the regimental level, as well as Army National Guard units. All are current through September 1, 2003. This is the companion book of The Organizational History of Field Artillery, 1775-2003.
