So I've heard this many times before, and even played it this way for a while. A unit in combat cannot attack a unit that assaults it next turn. If this is true it is a great tactic for my Tyranids again, but alas as I see it, it is crap. If you disagree and think you can explain it to me, please read through and tell me where I'm wrong.
I'm pulling from page 41 of the BRB and of the newest BRB FAQ.
For starters, the first sentence under Defenders React says "If a unit that is already locked in combat from a previous turn is assaulted by a new enemy unit, it can react as normal." so from right now I'm confused as to where people are coming up with this ruling. Maybe they are reading the bullet points.
- Models that were engaged with just one of the enemy units at the beginning of the (round of) combat (before any model attacked) must attack that unit.
- Models that were engaged with more than one enemy unit at the beginning of the (round of) combat (before any model attacked) may split their attacks freely between those units. Declare how they are splitting their attacks immediately before rolling to hit.
- Models that at the beginning of the (round of) combat (before any model attacked) were engaged with more than one enemy unit, but were in base contact with just one of the enemy units, must attack that unit.
To me it seems it comes down to when "before any model attacked" and "round of combat" are defined. How do you guys read it? I'm fine playing it either way, but I read it RAW one way. While playing it either way is fine, it is one of those things you need to know before you start the game, and sometimes it is funny asking that before the game. "So are you a Dem or Rep? Do you follow multi-assault prevention?"
