Shield
Gold (Yellow) recalls the Cavalry lineage of the unit. Gold is also emblematic of excellence and high achievement. The two horizontal black bars allude to wrought iron, inherent with Armor and the unit's numerical designation "2nd." The Spartan sword or Xiphos represents the unit's courage, vigilance and preparedness to stand and fight at a moment's notice. The blue of the hilt is for loyalty. The Spartan shield or Hoplon signifies the unit's ability to receive and organize multiple attachments for combat and remain constantly ready to support global military operations. Red symbolizes valor, sacrifice and is the color of the Spartan warrior's cape. The Spartan Army was one of the toughest on record and served as the standard for valor. The lightning flashes highlight the organization's inherent ability to support tactical missions with Intelligence, Signal and Military Police capabilities. The contrast of black and gold underscores the night and day, around the clock mission of the Special Troops Battalion.
Crest
The wings represent the wings of Mercury to highlight communications and signal and Daedalus, who soared above the threats unseen. Daedalus was a celebrated mythical craftsman who devised wings that made it possible for him to fly to his freedom. The five spears represent the organic abilities to command, control, communicate, provide intelligence and strike over the horizon at anytime. The silver Pegasus in flight signifies each soldier's ability to overcome any challenge and "Persevere Through Strength and Courage" in peace and war. All of the above also highlight the Special Troops Battalion's being awarded campaign credit for Iraq.
The coat of arms was approved on 4 October 2005. It was amended to add a crest on 1 February 2008.
