Master gunners are survivors of countless battles and have earned expertise that makes them some of the most valued artillerists in all Cygnar. Versed in all artillery skills, from barrage firing patterns to the use of defilades, they are experts in the complex commands used to coordinate a battery of field guns. Where other armies make use of artillery as support, the master gunners orchestrate their batteries into precision instruments of war. Trencher Master Gunner comes in a blister. A player may field two Trencher Master Gunners for each warcaster in a Cygnar army.
