Shield
The sword represents the effective power of the predecessor organization, the 158th Aviation Battalion's aerial weapons and the might of the organic fire support. The quillons (cross guard) composed of wings refer to the basic Aviation mission of the unit. The eagle wings also allude to the predecessor's assignment to the 101st Airborne Division. The speed and shock effect, characteristic of air assault operations, is indicated by the lightning flash. The peaks formed by the indented base refer to the mountainous area of Fort Carson, Colorado, where the former organization was activated. The one sword blade, five-segmented hilt, and cross guard containing eight primary feathers allude to the numerical designation of the unit.
Crest
The circlet of rice stalks, together with the colors yellow and red taken from the Republic of Vietnam National Flag, allude to the predecessor's service in Vietnam. The three arrows refer to the three decorations awarded the 158th Aviation Battalion for service during that period and the quiver, a piece of equipment used to transport war material, is symbolic of basic mission in providing tactical air movement of combat troops and weaponry.
The coat of arms was originally approved for the 158th Aviation Battalion on 12 March 1969. It was amended to add a crest on 13 September 1972. It was redesignated for the 158th Aviation Regiment with the symbolism revised effective 16 September 1987.
