Shield
Ultramarine blue is traditionally associated with Aviation units. The gyronny background simulates the movement of rotating blades of a helicopter and refers to the mission of the 159th Aviation in its airlift capability. The contrasting colors further symbolize the continuous (day and night) operations during visual weather conditions. The red bend and gold dragon refer to the service of the 159th Aviation Battalion in Vietnam.
Crest
The spearhead pointing skyward, together with the wings, symbolize Army Aviation's mission. The wings also represent the organization's mobile capabilities. The colors red, yellow and green reflect the unit's campaign participation credits and decorations in Vietnam. The palms are derived from the palm on the Republic of Vietnam Cross of Gallantry; they also recall the tropical terrain of Southeast Asia.
The coat of arms was originally approved for 159th Aviation Battalion on 22 November 1968. It was redesignated effective 16 November 1987, for the 159th Aviation Regiment with the symbolism revised. The insignia was amended to include a crest and revise the symbolism on 19 October 1989.
