Coats of arms of U.S. Army Aviation regiments are heraldic emblems associated with aviation regiments in the US Army. By Army regulation, all regiments of the US Army organized under a table of organization and equipment are authorized a coat of arms to be displayed on the organization's standard, called the "colors." This coat of arms also forms the basis for the unit's distinctive unit insignia (DUI), the emblem worn by all members of the unit on their service uniforms.
