A Gold color metal and enamel device 1 1/4 inches (3.18 cm) in height consisting of a shield blazoned: Per chevron Gules and Gray, a chevron rompu embattled to chief Argent between in chief the cipher "NG" and a lion rampant Or, and in base a bomb flamant of the last charged with the numeral seven Sable; surmounting a blue circular garter inscribed "PRO PATRIA ET GLORIA" in Gold, buckled Gold and folded at the top and surmounted by a Gold flintlock hammer.
Red is a color traditionally associated with Artillery, the original allocation of the units in the organization in 1806. The bursting bomb, the earliest insignia, represents that assignment. The old uniform was cadet gray; the monogram "N.G." was worn on it. For over fifty years the 107th Infantry Regiment was the only organization bearing the distinctive title of "National Guard." The rampant lion commemorates service in Picard, France, during World War I. The embattled and broken chevron is emblematic of the breaking of the Hindenburg Line, in which the 107th Infantry Regiment participated. The motto translates to "For Country and Glory."
The distinctive unit insignia was originally approved for the 107th Infantry Regiment on 26 February 1924. It was amended to correct the description on 28 March 1925. It was redesignated for the 207th Coast Artillery Regiment on 24 October 1940. The insignia was redesignated for the 107th Infantry Regiment on 30 March 1951. It was redesignated for the 107th Support Group with the description and symbolism revised effective 1 September 1993.
