Today the Force Structure and Unit History Branch continues the work begun by the Historical Section of the Army War College. The branch maintains historical information on active and inactive units in all components - Regular Army, Army Reserve, and Army National Guard, and prepares official Lineage and Honors Certificates. On the basis of research in primary and secondary material, the certificates outline the major organizational changes undergone by the unit and provide a list of the official battle honors (campaign credit and decorations) that the unit has earned. The information contained on the certificates is reformatted for publication in the Army Lineage Series
While it would take a book to recount the rich history brought about by the
changes of each unit in the 8th Cavalry Regiment, an overall look at the major
reorganizational elements of the Regimental Lineage presents a picture of an
organization that was accustomed to fighting and brought strength from
change.
