Scarlet and white are the colors used for Engineers. The white crescent on the blue is suggested by the State flag of South Carolina, the home area of the Battalion. It alludes to the Camden Rifle Company organized in 1812 and to service as Infantry prior to the unit's current Engineer combat designation. The blue area also refers to Savannah River, which forms the western boundary of South Carolina and of Edgefield County in which Edgefield, the Battalion's headquarters, is located.
The crest is that of the South Carolina Army National Guard.
The coat of arms was approved on 16 August 1956. It was amended to correct the English translation of the motto on 1 March 1971.
