The design of the 130th Maneuver Enhancement Brigade’s Distinctive Unit Insignia, also called a unit crest, was originally approved on 29 October 1929 when the Brigade was designated the 105th Engineers. It was under this designation that the unit fought in World War I as part of the 30th Division, and the unit crest’s symbology was inspired by those actions.
Three fleurs-de-lis on the red field are taken from the coat of arms of St. Quentin and stand for the three overlapping actions in which the unit participated: the Somme Offensive (8 August 1918 until the Armistice), Ypres-Lys (19 August until Armistice), and Flanders 1918. The shattered bend represents the 105th Engineers Regiment’s role as combat troops in helping break the Hindenburg line at the Battle of St. Quentin Canal in late September 1918, inspiring the unit motto “Ever Dependable” (but this was not added to the insignia for some fifty years).
