Shield
Ultramarine blue is traditionally associated with Aviation units. The alerion (a heraldic eagle without beak or talon) is symbolic of flight and further suggests the fixed wing variety of aircraft. The star, a symbol of achievement, also represents rotary-winged aircraft. The nebuly partition line is suggestive of clouds and sky.
Crest
The lightning bolts issuing from a cloud refers to the mission and capabilities of the 1st Aviation Battalion in combat service. Yellow and scarlet, the colors of the Republic of Vietnam flag, refer to the 1st Aviation Battalion's service in 11 campaigns there. Two awards of the Meritorious Unit Commendation are represented by the scarlet lightning bolts at center, and the two yellow bolts connote awards if the Republic of Vietnam Cross of Gallantry with Palm and Civil Action Honor Medal, First Class.
The coat of arms was originally approved for the 1st Aviation Battalion on 17 Feb 1964. It was rescinded on 8 July 1976. On 1 Sep 1981 the coat of arms was reinstated and amended to change the color of the shield and to add a crest. The coat of arms was redesignated to the 1st Aviation with the symbolism revised on 16 Nov 1987.
