Except for its shape, the 4th Infantry Division's Unit Crest
, or Distinctive Unit Insignia, is based almost entirely on the design of its CSIB (Combat Service Identification Badge)
. It features a single leaf of an ivy plant, which is a symbol of fidelity and stick-to-itiveness. These themes are mirrored in the unit motto, "Steadfast and Loyal," emblazoned on the scroll encircling the bottom hemisphere of the insignia.
