The key denotes the security of the unit's military supplies for distribution to supported organizations. The hammer signifies the maintenance of all the Brigade's vehicles required for sustainment of the missions. The dancett suggests the mountainous terrain of the Franklin Mountains, outside Fort Bliss, Texas, the birthplace of the Brigade Support Battalion. The star indicates the command and control for the original support branches which form the unit: transportation, quartermaster and ordnance.
