The 158th Aviation Regiment Distinctive Unit Insignia was originally approved for the 158th Aviation Battalion on 6 June 1969 and was redesignated for the 158th Aviation Regiment on 16 September 1987. A winged sword superimposed over a lightning flash is the most prominent imagery in the insignia, with the sword symbolizing the firepower of the 158th Aviation Battalion’s aerial weaponry and the wings—which form an elaborate quillon, or cross guard for the grip of the sword—denoting the Aviation mission of the organization and alluding to its former assignment to the 101st Airborne Division.
A lightning flash signifies the speed and “shock and awe” inherent in air-assault operations. The trio of mountain peaks is an allusion to the mountains surrounding Fort Carson, site of the organization of the 158th Aviation Battalion. The unit’s numerical designation is symbolized by a single sword (1), five hilt segments (5), and eight primary feathers on the two wings. “Challenge” is the unit motto.
Also known as a unit crest or DUI, a Distinctive Unit Insignia is worn by all Soldiers (except General Officers) in units that have been authorized to be issued the device. It is worn centered on the shoulder loops of the Army Green Service Uniform (AGSU) and the blue Army Service Uniform (ASU, Enlisted only) with the base of the insignia toward the outside shoulder seam. DUIs are not worn on the Dress variations of either uniform, however.
