Well In John, is Gming you will have to speak to him about that chris. And no, if the leader falters in combat or is suspect of heresy it is a commissars duty to execute. As I read the rules, I think I can only really execute Comrades, which gives the party buffs ect, but I guess there is nothing to stop me executing a player, if I was really roleplaying the crap outa my character( or I felt like being an arse) But If your Read the Book Iron Guard by Mark Clapham ( which features the Mordian Iron Guard) , there is a scene in there where the Regimental commissar executes the ranking sergeant and inspires the men to victory of a skirmish. Nothing damages moral like a officer who does not know what they are doing or is running, I think in the rule book of Only war there is anther example.
