muskets work MUCH better if put in skirmish mode, this is becose each man picks his own target instead of fireing in volleys, increasing rate of fire at the whole unit doesnt hav to be prepared before people can begin fireing, also, it results in a continuous rate of fire without having to reform for each shot, saveing time, and against musketters in line formation they will be trying to reform continuously due to their continuous rate of casualties, decreasing their rate of fire
