They all display the Confederation crest in addition to the Cavalry emblem, an armored knight with a red plume in his helm rising from a green triangular field. Each regiment except for the Wild Ones also displays a regimental insignia, usually on the back of the shoulder or the upper leg.
In lieu of their own emblem, the unit uses an oversized version of the Armored Cavalry insignia. They have yet to add the Confederation crest to their 'Mechs, though all other vehicles display it prominently.
