If, at Initiative step 5, a unit takes so many casualties in close combat that its Initiative step 3 pile-in move cannot bring any models into base contact, does that unit get to swing at Initiative step 3? Does the combat immediately end?
This situation has happened a few times playing a bike army, so I wanted to make sure I'm playing all this correctly. I got tryhard and made this specific example with a lot of questions:
A Dark Angel Warlord and his Librarian buddy charge a unit of two Adeptus Mechanicus gravbots with a Tech-Priest. They barely make the charge, such that the Warlord is the only model in base contact. All other models are in a line two inches apart. There are no casualties from Overwatch or Hammer of Wrath.
At Initiative step 5, the Warlord swings and kills the single gravbot model he's touching. At Initiative step 3, the remaining gravbot makes a 3" Pile In move, but still no models are in base contact. The Tech-Priest and Librarian have Unwieldy axes and so do not Pile In until Initiative step 1.
What happens now? Does the gravbot get to swing after Piling In? Probably not.
Does the combat continue to Initiative step 1? I'm not sure. Even if it did, neither the Tech-Priest nor the Librarian can close the gap.
So does this combat end after Initiative step 3? Or after Initiative step 1?
Do they next determine who has won the combat?
If the Adeptus Mechanicus don't Fall Back, do both units then make an End of Combat Pile In move?
If they get this far, it's hard to imagine that wouldn't bring them back in base contact, but mass casualties could cause this. If this last Pile In doesn't work, it looks like both units Consolidate.
Rules References:
Page 48 states "At the start of each Initiative step, any model whose Initiative is equal to the value of the current Initiative step, that isn't already in base contact with an enemy model, must make a Pile-In move." That's three inches.
Page 48 also says "If both players' Pile In moves combined would be insufficient to bring any combatants back together (that's more than 6" - very unlikely!), the assault comes to an end. All remaining Initiative steps are lost -- work out the assault result ..."
"A model is engaged if:
* It is in base contact with one or more enemy models.
* It is within [unit coherency] of a friendly model in base contact with one or more enemy models in the same combat."
Page 52 says "all of the models in the target unit may be [...] casualties during an Initiative step, including those that are not engaged."
Any more relevant rules?
