Symbolism
Scarlet and yellow are colors traditionally associated with Artillery units as well as the cannon barrel. The wings are indicative of the mobility, speed and devastating accuracy of the modern artillery.

Background
The shoulder sleeve insignia was originally approved for the 18th Field Artillery Brigade on 29 May 1979. It was amended to include the airborne tab, add metric measurements and revise the description on 21 October 1992. It was again amended to change the color of the airborne tab on 5 February 2003. The insignia was redesignated for the 18th Fires Brigade and amended to delete the airborne tab on 22 March 2007. (TIOH Drawing Number A-1-639)
