Mary Lee Stubbs (Chief of the Organizational History Branch of the O.S. Office of the Chief of Military History) and Stanley Russell Connor (Deputy Chief of the U.S. Organizational History Branch, OCMH) wrote the 1968 Armor-Cavalry Part I: Regular Army and Army Reserve, part of the Army Lineage Series, which was "designed to foster the esprit de corps of United States Army units."

This book traces the lineage & honors of the currently active 55 Army National Guard Armor & Cavalry regiments. The lineage of a unit is its military history. It includes the organization of a unit, its entry into Federal service, & any reorganizations, redesignations or conversions the unit may have undergone. The honors of a unit consist of wartime campaigns & unit decoration streamers. Lineages for National Guard units are published at the regimental level as are the lineage & honors of the regiments included in this book. If a regiment is authorized a distinctive unit insignia it is shown to the left of its regimental designation.
