Hi! You´re probably right about the nomenclature deviation, I´m afraid. Although, about the "scale", I played this mission a couple of times with my group as a skirmish, and the small amount of models in units ended up turning the mission too "deadly" (groups of 1 to 3 guys just standing in open terrain waiting to roll at the end of the turn... easy prey for anyone with ranged attacks) so it seemed more a fight to the last one standing and the objectives lost relevance. I submitted it as non-skirmish so that wouldn´t happen so often.
Thanks for reading and commenting, anyway. Cheers!
