Ok, so after having a look around. the rules-as-written are woefully lacking in the shooting department.
lets say ive got a hoard of empire handgunners. i wack a skirmish line of 5 archers in front of them like so.
now if i want to shoot unit x, as far as i can tell. i need to draw line of sight to a model in that unit. the unit gains hard cover if 51% of it is obscured from the shooting model. as far as i can see in this situation, every signle one of my models at eye level are going to be able to draw un-obscured line of sight to at least 6 individual members of that unit. like so
does granting hard cover apply on a per-model basis, or on a per-unit basis. i understand how hard cover would be granted by a hill that only showed like, the top half of some cavalry. or is there still a rule in 8th that i cant find that grants hard cover -just- for me shooting through my own units?
