Crossbows from rear ranks (shooting through front units)

I zoomed in on unit of my crossbows standing on a bridge and darned... I started to miss MTWI. In the older version of the game, only the front row of a crossbow unit would shoot (second, while the front would be reloading). In MTW2 - it's RTW all over again. My bridge crossbow unit was 15 ranks deep and ALL the ranks were shooting not even in a arch (as they do in a silly fashion when placed on walls) but in a straight line right through the front ranks... I will post a screenie later. Looks funny (and no friendly fire casualties...).

thats weird, my x-bows usually shoot in an arc is theres something in front of them O.o;
oh and no volley fire it seems =P. they just randomly shoot.
