Gold and red are symbolic of the traditional colors of the garments worn in battle by the ancient Hawaiian warrior chiefs. The shark tooth weapon recalls the Hawaiian infantry warrior engaged in close combat, the twenty-nine teeth refer to the 29th Infantry Brigade Combat Team. The lightning flash tips of the spears represent the signal and intelligence missions of the Battalion and denote speedy response. The woven embattled chief, patterned in the manner of traditional Hawaiian woven lauhala matting, signifies the engineering and special mission skills of the Special Troops Battalion. Respectively, scarlet and gold represent courage and excellence.
The crest is that of the Hawaii Army National Guard.
The coat of arms was originally approved for the Special Troops Battalion, 29th Infantry Brigade Combat Team on 17 March 2008. It was redesignated effective 1 September 2014, for the 227th Engineer Battalion with the symbolism revised.
