In the Rogue Trader on p. 247 it indicates:
Shooting into Melee Combat Ballistic Skill Tests made to hit a target engaged in melee combat are Hard (–20). If one or more Characters engaged in the melee is Stunned, Helpless, or Unaware, this penalty is ignored.
Full stop. That is the extent of what it says. Full auto and Semi auto fire give a
+10 bonus, respectively. Nowhere that I can find is there any indication what the rule is if you miss.
To illustrate, if you've two melee fighters tangling with a sorceror in melee, and a someone with a fully automatic weapon fires into the crowd, with full auto, they have a
+0 chance to hit. And if they miss (or even if they hit but not with every bullet they fired) none of the other melee fighters are hit. This seems non-sensical.
Offhand, I'd expect:
- Increasing difficulty to hit your target based on the number of melee fighters, starting with
-20for two fighters and going up from there.
- Some sort of rule for handling stray bullets. Given the themes of 40k, I'd expect them to be gruesomely awful for your friends locked in melee combat.
But I can't find anything along these lines. Does Warhammer 40k provide any to handle this situation? (It would seem odd to not, given that they have clearly conceived that the situation exists.)
