MottoSUPPORTING THE FIRES.
ShieldBuff is the primary color for Support units. The rayonne, phoenix and arch of three arrows points in base refers to the link between the Battalion and the 171st Field Artillery with the three arrow points taken from the coat of arms of the 171st and indicates that the Battalion is carrying on the history of the 171st Field Artillery. The blue of the phoenix is taken from the background of the Oklahoma State flag. The two olive branches, seven eagle feathers and calumet refer to the unit's numerical designation and are also taken from the State flag and symbolize the unit's tie to the State.
CrestThe crest is that of the Oklahoma Army National Guard.
The coat of arms was approved on 30 September 2010.
