Teal blue and white are the colors formerly used for Aviation battalions. The diagonal stripes allude to the shoulder sleeve insignia of the 3d Infantry Division, to which the unit is assigned. The wings represent the mission of the unit and their position above the stripes represents the aviator flying above the supported organizations. The style of wings is similar to the wings associated with Army aviation.
The distinctive unit insignia was originally approved for the 3d Aviation Battalion on 29 August 1963. It was amended to correct the symbolism on 6 September 1963. It was rescinded on 8 July 1976. It was reinstated for the 3d Aviation Battalion and amended to revise the symbolism on 10 April 1978. The insignia was redesignated for the 3d Aviation Regiment with the description revised on 1 July 1987.
