The Distinctive Unit Insignia (also called "unit crest") of the 123rd Armor Regiment, Kentucky Armor National Guard was originally approved for the 149th Infantry Regiment on 27 October 1925. It was amended less than a year later to correct the blazon (heraldic term referring to the formal description of an emblem or design), and in January 1956 it was redesignated for the 241st Tank Battalion. It was redesignated for the 123rd Armor Regiment on 23 September 1960 and was subsequently amended to change the symbolism on 2 October 1969.
Blue is used for the shield portion of the insignia to reflect the unit’s heritage that began with the organization in 1846 of the 2nd Kentucky Volunteer Infantry Regiment. Civil War service is signified by the white saltire from the flag of the Confederacy (but with the red portion now blue), and service in the Mexican War at the Battle of Buena Vista is denoted by the cactus and snake taken from the Mexican flag. Ermine in the chief (upper one third of the shield) represents World War service in Europe and is from the coats of arms of Nantes and Brittany. The unit motto, ESTO PERTUA, is a Latin phrase meaning “May It Live Forever.”
