Like the Distinctive Unit Insignias of other Armored Divisions, the 3rd Armored DUI features its Special Designation—"Spearhead"—on a rectangular base with an equilateral triangle placed upon it. Mobility, firepower, and speed are represented by the images of a tank tread, the barrel of a cannon, and a bolt of lightning. The tri-color design is employed to represent the three types of forces—cavalry (yellow), infantry (blue), and artillery (red)—that make up an armored division.
Also like other armored divisions but unlike all other types of units that have been assigned a Shoulder Sleeve Insignia / Combat Service ID Badge, its Distinctive Unit Insignia is essentially identical to its SSI, with the only significant difference being the display of a motto or Special Designation on the unit crest.
The 3rd Armored Division Distinctive Unit Insignia was approved on 3 June 1983.
