A gold color metal and enamel device 1 1/8 inches (2.86cm) in height consisting of a gold disc encircled by a red scroll folded back upon itself in base and inscribed 'WE TRAIN TO" on the left and "MAINTAIN" on the right in gold letters, overall a black bomb emitting gold flames to top and two lightning bolts, one on either side, arcing to base, all superimposed by a gold right hand gauntlet grasping an upright gold sword with a white blade.
Crimson (red) and yellow (gold) are the colors associated with the Ordnance Branch. The flaming bomb suggests the unit's mission. The two lightning bolts represent the unit's World War II combat action: the campaign streamer for Air Offensive, Japan and the Meritorious Unit Commendation for the Pacific Theater. The red color of the lightning bolts also refers to the Meritorious Unit Commendation and the Rising Sun on the Japanese flag. The gauntlet grasping the sword symbolizes the unit's readiness and its determination to accomplish its military mission.
The distinctive unit insignia was authorized on 13 Nov 1986.
