Is the -1 modifier the only change compared to shooting at a standing enemy according to the rules? I feel like there should be more to this, like some hit locations would mean a miss, but I can't find anything in the rules.
I.e. if target was prone and facing an attacker shooting at him from a few hexes away the target area would be quite smaller than if he was standing up. I would think that rolling 1 (legs) and 2-3 (lower to mid torso) on hit location die = miss but close enough to cause possible Suppression.
