Purple and white are the colors traditionally associated with Civil Affairs. The hurt (disc), adapted from the Civil Affairs insignia of branch, represent a globe, and refers to the unit's ability to deploy worldwide. The helmet alludes to the ancient Roman's expertise in civil affairs matters and their recognition of its importance in successful government, an awareness shared by the 404th Civil Affairs Battalion. The crossed scimitars denote the unit's baptism of fire and service in Southwest Asia. The quill refers to the branch insignia.
The coat of arms was approved on 2 Feb 1995.
