Better known as a unit crest and commonly referred to as a DUI, the Distinctive Unit Insignia of the 206th Support Battalion, also known as the 206th Corps Support Battalion, was approved on 13 November 1967 while the organization was still designated as the 106th Maintenance Battalion. The Battalion’s previous designation as the 106th Ordnance Battalion is recognized with the crimson and yellow, the colors of the Ordnance branch, used in the design.
A rose in the center is a reference to the organization’s home state of New York (it is the state flower), while the star superimposed on it is a symbol of guidance being constantly maintained by illumination; it is also a reference to the unit motto, “Stellar.” Together, the rose and the star simulate a wheel and invoke the concepts of mobility and supply; the wings on the sides of the insignia are an allusion to air transport.

Distinctive Unit Insignias are 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.
More guidance on wear of the DUI is found in DA Pamphlet 670-1, Section 21-22, "Distinctive unit insignia" and 21–3(d) and (e), "Beret" and "Garrison Cap," respectively.
The 206th Support Battalion is a unit in the New York Army National Guard that is no longer active. It is unclear whether the unit was inactivated, deactivated, disbanded, redesignated, or reflagged, but it does appear to have been inactivated temporarily between 1994 and the start of the Global War on Terrorism.
