Shield
The original units of the regiment were artillery and 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." This designation was adopted by the United States Government for general use in 1869. 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.
Crest
The crest is that of the New York Army National Guard.
The coat of arms was originally approved for the 107th Infantry Regiment on 2 August 1923. It was amended to correct the blazon of the shield 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. The coat of arms was cancelled on 3 June 1993, when the distinctive unit insignia was redesignated for the 107th Support Group; as the Group was not eligible to inherit the coat of arms.
