I dunno about that. I seem to be able to click the ram itself just fine to target it. It's impossible to tell whether the archers target the 6 or so men that are lugging it around or are targeting the actual ram, but certainly they are not firing at the center of the entire unit attached to the ram, as their usual practice would be if they just targeted the unit as a whole. In my example above about burning a ram while it was at the gate, whole flights of arrows were landing directly on and around the exact spot the ram was on.

BTW I'm not sure right now what exactly you mean by targeting the "men lugging it around" though I've interpreted that as the entire associated unit, since you describe only strays hitting the actual ram. With that in mind, I hope my explanation and understanding is sufficient.

It's possible what you're seeing is separate arrow-targeting issues. If you're firing grouped archers or have your archers set to fire at will, they will often not target what you actually click on. Grouped archers seem to love to each select the closest enemy unit to them as a target instead of whatever I indicate, and archers on fire at will seem to be prone to similar target selection, just on a per-unit level (i.e. even if you only have one selected they can decide to shoot a different target than you indicate). At least, that's been my experience, so if I intend to designate targets (almost always) then my archers receive orders one unit at a time, and never have their fire-at-will mode on. It's also possible (nay, I vote it likely) that those targeting routines do not include siege equipment as potential targets, in which case even if you order them to attack the ram as a group or with fire-at-will on, you'll probably never even get them to accidentally shoot it as the closest target.

I hope that solves it for you.
