Lord Carson's Cavaliers
The Cavaliers paint their vehicles dark green with white-stripes.
Per FM:Capellan Confederation, page 90.
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.
The unit's insignia is a coat of arms over two crossed lances.
