20th Engineering Battalion
Lineage/DateLine
"Build and Fight"





The Army did not begin a formal program for determining lineage and honors until the 1920s. Before that time, considerable confusion existed within the Army about the accepted procedures and methods for determining the prior history of units and their entitlement to battle honors. With the demobilization of the Army following World War I, many distinguished units were lost from the rolls. To avert such problems in the future, the Historical Section of the Army War College assumed responsibility for maintaining historical information about Army units: thus lineage work began.

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 15th Brigade Support Battalion, an overall look at the major reorganizational elements of the Battalion Lineage presents a picture of an organization that was accustomed to fighting and brought strength from change.
