Army Lineage Series

"The Army Lineage Series is one of the oldest series of volumes published by the Center of Military History. Over time, the scope and concept of the series have evolved considerably, but the purpose has remained the same: to provide a compact, readily available source of information on unit organizational history. All lineage volumes have included illustrations and descriptions of unit insignia designed and manufactured by The Institute of Heraldry. Many volumes have included narrative essays of varying lengths discussing the evolution of the branch. Some branches/echelons have been covered in multiple volumes with the narrative published separately from the lineages. Most have also contained unit bibliographies. Because of the specialized terminology used on the certificates, most volumes also include a glossary." Source:
