It's somewhat reflected in this game... only one rank fires at a time, then they change places (They haven't learned the kneel and have the next rank fire over your head trick yet I guess)
I'm fairly certain that this technique was perfected by Napoleon, so it's no wonder that the arquebusiers don't employ it. This would be tantamount to me being upset because my armies don't use a blitzkrieg strategy well enough.
