When a DUI is authorized, all personnel assigned to the organization wear the insignia, except general officers, the Sergeant Major of the Army and the Senior Enlisted Advisor to the Chairman. General officers wear their regimental distinctive insignia (RDI) on the black pullover sweater. The Sergeant Major of the Army and Senior Enlisted Advisor to the Chairman (if a soldier) wear, respectively, the SMA and SEAC collar insignia in lieu of the DUI on their pullover sweaters and berets, but their epaulets are bare.
