As with other reserve divisions, the Victoria Commonality Rangers use the Confederation crest as their only insignia aside from a regimental emblem. Their version of the crest is backed by a steel-colored field.
The unit's regimental crest is a triskelion comprised of weapons set against a beige triangular field. The blades pointing to the upper corners are the Han dao and a Greek kopis, representing the Confederation and the Magistracy, respectively.
