That is EXACTLY what I'm saying. WarKirby's reply was because I said I didn't want polearm line because polearms wouldn't do them much if they weren't disciplined. Something promotions represent, not unit-lines, represent.
Also I'm not sure courage is the right word since this isn't about a guy choosing to stand and fight a foe that has a very real chance of killing him (such as a dragon). I'm talking about, for example, a squad of pikemen who's response to having a cavalry unit crash into them causing a lot of casualties before pulling out for another charge, isn't to run but to reform and brace for impact. Then when they have received another charge, cavalry have pulled out again and they have lost a lot soldiers, they reform and brace for impact again. Receiving another charge and continuing that way until the cavalry have lost so many soldiers in a war attrition, that when they charge again they can't pull out and are instead surrounded and killed to the last man by the pikemen. IIRC a squad of Swiss pikemen pulled that exact feat of in a battle whose name I can't remember.
