Fully agree with OP!
Some kind of morale is a must to be added, else the game will fail to deliver Civil War feel.
Making coulrs bearer ability of "healing" and "boosting" morale for friendly soldiers will give this class realistic role. "Boosting" morale by following officers' commands and by staying close to teammates, while losing morale facing enemy alone - this will prevent "ramboing" in proper way.
Thanks OP for one of the best posts here!
